Is Internet Phone (VoIP) Worth the Switch?

You've seen the advertisements. You probably know at least one person who has tried it, but is Voice Over Internet Protocol (VoIP), a.k.a. Internet phone or digital phone, for you? Let's face it. Your traditional phone service works pretty well, so why switch? The answer is savings.

Let's start with the basic monthly plan. The average monthly residential Internet phone plan is approximately $25/month. Business plans are roughly double the residential rate. Usually included within this price are loads of free features like voice mail, call waiting, three way calling, caller id, and call forwarding. Traditional phone service ranges from approximately $15/month to $60/month depending upon add-ons, long distance, taxes, and surcharges. Internet phone service may be for you if you are on the higher end of this scale. Moreover, many cable companies offer Internet phone service as part of a bundled package- Internet, television, and home phone service on one bill. This combination may prove to be very cost effective.

International calls are extremely cheap with Internet phone. Rates can start from around
$.02/min., depending upon the destination country. Also, some calls may even be free. For example, if you subscribe to XYZ Internet phone service, and you call a friend overseas who also subscribes to XYZ, the call should be free. You can even take your Internet phone service with you when you travel. If you have a wi-fi Internet phone, you should have service wherever there is a wi-fi hotspot worldwide. Or if you take your hardware with you (i.e. telephone adapter, router, IP phone), you should be able to use your service wherever there is a broadband Internet connection available. Thus, frequent travelers or people with overseas relatives and friends would greatly benefit from Internet phone service.

Business owners stand to benefit the most from switching to Internet phone service. High long distance volume, systems integration, phone number mobility, and local market presence are the main reasons why. First, businesses have inherently high call volumes, especially domestic and international long distance. VoIP should lower these expenses, lowering monthly overhead. Second, VoIP is highly flexible and meshes well with other business applications. Third, businesses spend thousands of dollars annually on advertising, and those dollars are wasted if a phone number has to be changed. VoIP allows a business to keep the same number regardless of location changes. Closely related is the issue of local market presence. With VoIP, businesses can have a local phone number but be located in a different city, state, or country. The cost to you is just a local phone call. Despite the many benefits of VoIP for businesses, there is one major concern - security. Since voice conversations travel via the Internet, VoIP systems are susceptible to the same perils as your computer (i.e. hackers, viruses, etc.). Small to medium sized business are less of a target than larger businesses. However, all businesses utilizing VoIP should have up-to-date security software and contingency plans in place to minimize the threat.

Despite the many benefits of VoIP, there are a few issues that require consideration. These issues include: voice quality, power outages, emergency services, alarm systems, fax capabilities, digital video recorder (DVR) devices, local number portability (LNP), and broadband Internet requirement. For you, these issues may be just a intermittent irritation, like a dropped phone call or poor signal reception during a cell phone call. For others, these concerns could be insignificant or a deciding factor.

With Internet phone service, voice quality depends heavily upon the quality of your high speed Internet connection. So if your connection is not fast enough, voice quality may be inconsistent. It's always best to test your broadband connection with a VoIP speed test before subscribing.

Presently, unless an alternate back-up power source is readily available, Internet phone service will not work during a power outage because vital pieces of equipment such as routers, analog telephone adapters, and modems require power. Aware of the problem, some companies supply equipment with built-in battery back-ups. Other companies will route calls to an alternate phone number during an outage. Or, you could purchase an Uninterruptable Power Source (UPS) to provide power during an outage. The amount of power supplied by UPS's will vary by model and price. Barring the aforementioned, be ready to use a cell phone during a power outage, or consider keeping a bare minimum landline as a back-up.

In 2005 VoIP companies that interconnected with the public telephone network were required by the Federal Communications Commission (FCC) to provide 911 service and disclose service limitations. When you dial 911, calls are routed through a Public Safety Answering Point (PSAP). E911 (Enhanced 911), which is utilized in many areas, allows the PSAP to automatically discern your location. Due to the dynamic nature of VoIP, your location is more difficult to determine. Many companies have bypassed this obstacle by sending the PSAP the address of the subscriber. However, all PSAP's are not set-up to receive VoIP data. In which case, you would have to provide your location to the call center. As more and more people use Internet phone service, upgrades are being made to provide E911.

Presently, most alarm systems use a landline for monitoring purposes. Your alarm system may work with VoIP, although some equipment adjustments and testing may be required. Since VoIP data travels at higher speeds, these adjustments involve the lowering of these speeds. Similarly, faxes may be sent over a standard VoIP line, with equipment adjustments needed in many cases. To mitigate this problem, many companies offer designated fax lines as an add-on or as part of a business service plan. Additionally, many digital video recorder (DVR) devices require landlines to receive updates. However, some subscribers have reported successful DVR operation with VoIP. For a seamless transition, if you already have a DVR, you may want to check to see if it has a broadband port before subscribing to VoIP service.

When subscribing to Internet phone service, many people prefer to keep the same phone number, and in most cases this is possible through local number portability. LNP is the process by which consumers can transfer their phone numbers when changing telecommunications carriers. This process can take from approximately 10 to 20 business days until completion.

Finally, VoIP requires a high speed broadband Internet connection. For those of you who already use broadband Internet, this is not an issue. However, millions of people still use dial-up or have no Internet access at all. Therefore, this segment of the population must evaluate the cost of upgrading to broadband Internet versus the benefits of Internet phone service.

Is VoIP worth the switch? Individual answers will vary. Using the aforementioned considerations, a side-by-side comparison between your traditional phone service and your potential VoIP provider should prove to be informative at the very least. Savings is the key. If your potential savings outweigh all other factors, by all means, internet phone service should be worth the switch.

New Age Solutions for New Age Business

The problems of today require new age solution. And modern business has to stay up to date with the changes that are constantly taking place. Technological advances have made it necessary for offices everywhere to deliver quickly and efficiently. There is cut-throat rivalry in every line of work. A slight hiccup here and a faltering step there might result in the slipping away of a lucrative contract. Businesses today do not have the luxury of dilly-dallying with their decisions. Everything has to be instant. A minute more could result in losses for the business. That is the way of the world today, and every business organization has to adapt itself to the various needs of the world.

Conference calling has been one of the solutions that more and more businesses are finding to be a great option. Now, conference calls have been around for a while. They are not new entrants to the business world. However, conference calling has become much faster. It has become far more convenient. And it is widely regarded as a great way of starting discussions with people located across the globe. With globalization having spread its influence, one cannot help but recognize the power of a conference call to facilitate business decisions. People who are located miles away from each other can be brought together via the power of technological progress.

Moreover, the look of the age-old conference call has also changed. One no longer has to reserve a con call much before the desired time. Conference call booking these days happens within minutes. Also, a conference call no longer has to be restricted to the audio mode. These days, with the rise of the Internet, and the popularity of web conferencing, most conference calling services are now starting to offer video conferencing facilities. So, conducting a conference call is quite similar to a meeting in the conference room. The personal touch that might have been missing in the audio conference calling facility can be gained via audio-video conferencing.

Conference calling is a great way of creating links with the problem of having clients and colleagues who are situated abroad. Their travel and accommodation expenses might have amassed to a higher amount than that of conducting a conference call. Most conference calling services that you might look up will provide a variety of rates and bargains to suit the needs of various customers. Whether one decides to go with web conferencing or audio conferencing would possibly be affected by the amount of money that is at hand and the requirements of the meeting. The need of the day seems to be customized conference calling.

All About Satellite Radio

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the providers income comes from listeners and not from advertisers. Satellite radio services offer around 70 programs of commercial fee music channels each and you have a great variety of choices, from mainstream rock, hip-hop and dance music to folk music, opera, blues and many more.

Another great thing is the absence of static. You can be driving from the West Coast to the East Coast in the United States of America and you will not get any static at all on the way. The radio signal is digital, which means that you will get crystal-clear sound wherever you go.

Satellite radio tuners receive, along with the actual radio programs, an influx of metadata that consists of information regarding song title, artist, radio program and radio channel. This means that your satellite radio receiver will display all the necessary information about what you are listening to. For instance, if you hear a great song and you want to know which artist sings it, you just look at the receivers display.

All radio programs are uncensored. This is one of the reasons why artists like Howard Stern chose to move their shows on satellite radio. You can also listen to your favorite hip-hop songs without the interruption of those annoying beeping sounds.

Satellite radio programs also offer information about local traffic and weather conditions. The information is very detailed especially for those who live in big cities. If there is a major national calamity and other terrestrial radio stations will not work, you can always count on getting accurate information from satellite radio program. You can also listen to it online on your computer.

If you still are not convinced on why you should pay money for something that you can get for free, think about how much time you have wasted listening to commercials and all kinds of other boring stuff on terrestrial radio programs.

Traditional radio is not free, despite the popular belief. It is time-consuming and irritating because you have to listen to five minutes or more of commercials so that you can finally hear a song you like. The satellite radio subscriptions are very affordable and, for around 13 dollars per month, you get exactly the programs you want, which you can listen to wherever you are, at the best sound quality.

Satellite radio is great for you especially if you travel a lot. If you are traveling across the United States of America, for example, you can listen to the channel or channels you want during your whole trip, without losing signal or getting static. If you have a traditional radio, you will have to keep changing channels every hundred miles, but if you are using satellite radio you do not have to do that because the geographically availability of programs is not a problem. Satellite radio subscribers will soon get the chance to watch video programs as well.

Both Sirius and XM services have announced their intention of introducing in the near future a variety of video satellite channels that will have some of the great advantages that are currently available to satellite radio: commercial free programs, great quality of sound and vast geographical availability.

Bluetooth Enable a Perfect Wireless World

What is Bluetooth?
Bluetooth is an industrial specification for wireless personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, personal computers, printers, GPS receivers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group.

Bluetooth Specification
The Bluetooth specification was developed in 1994 by Jaap Haartsen and Sven Mattisson, who were working for Ericsson Mobile Platforms in Lund, Sweden. The specification is based on frequency-hopping spread spectrum technology.

The specifications were formalized by the Bluetooth Special Interest Group (SIG), organised by Mohd Syarifuddin. The SIG was formally announced on May 20, 1998. Today it has a membership over 7000 companies worldwide. It was established by Ericsson, Sony Ericsson, IBM, Intel, Toshiba, and Nokia, and later joined by many other companies.

Bluetooth Organization
The Bluetooth Special Interest Group (SIG) is a privately held, not-for-profit trade association. The Special Interest Group was founded in September 1998. The Bluetooth SIG itself does not make, manufacture, or sell Bluetooth enabled products. The SIG has more than 9,000 member companies that are leaders in the telecommunications, computing, automotive, music, apparel, industrial automation, and network industries. SIG members drive development of Bluetooth wireless technology, and implement and market the technology in their products. The SIG has a small group of dedicated staff in Hong Kong, Sweden, and the USA.

The Ipod Generations

The original iPod (mp3 mp4 player) introduced on 23 October 2001 marked the first iPod generation, and the latest iPod introduced on 12 October 2005 marked the fifth iPod generation, which was subsequently revised with a revision iPod model on September 2006, often referred to as generation 5.5. Note that the generations are referred with reference to the model name and not with reference to the date of release.

For a better understanding about iPod generations, check the following:

On October 23, 2001, the first generation of iPod was released. The model name was iPod and had the storage capacity of 5 to 10 gb. It used FireWire connection to computers and it had a mechanical scroll wheel.

On July 17, 2002, the second generation of iPod was released. It had the storage capacity of 10, 20 gb. It used FireWire connection to computers and it had a touch-sensitive wheel. The Hold switch was revised. The FireWire port had a cover.

On April 28, 2003, the third generation of iPod was released. It had the storage capacity of 10, 15, 20, 30, 40 gb. It used FireWire connection to computers (USB for syncing only), and it had a central row of touch sensitive buttons. New backlit screen was introduced. Dock connector port was introduced.

On January 6, 2004, the first generation of iPod mini was released. It had the storage capacity of 4 gb. It used FireWire or USB connection to computers, and it introduced the "Click Wheel", which was later adopted by the fourth generation iPod. It was available in 5 colors.

On July 19, 2004, the fourth generation of iPod was released. It had the storage capacity of 20, 30, 40, 60 gb. It used FireWire or USB connection to computers, and buttons were integrated to form "Click Wheel". The monochrome model was replaced in June 2005 by the color display with photo viewer, which was introduced in October 2004.

On January 11, 2005, the first generation of iPod shuffle was released. It had the storage capacity of 512 mb, 1gb. It used USB connection to computers, and it had no screen, no click wheel. It used flash memory instead of hard drive storage.

On February 22, 2005, the second generation of iPod mini was released. It had the storage capacity of 4, 6 gb. It used FireWire or USB connection to computers , and it had longer battery life, and brighter color variants. Gold model discontinued. No AC adapter. The body color matched the click wheel lettering.

On September 7, 2005, the first generation of iPod nano was released. It had the storage capacity of 1, 2, 4 gb. It used USB connection to computers (FireWire for charging only), and it was the successor of iPod mini. Slimmer design, flash memory, color screen and lyrics support.

What Makes The Ipod Sell?

People have intense love affairs with their machines, like some men are known to be enthusiastic about their cars, and some women are known for some household appliances. But the iPod seems to top them all and seems to pull strings at the heart with such consistency that some people, irrespective of age, sex, color, and creed, make the mp3 player device an extension of themselves, an extension of their personalities, and an extension of their lifestyles!

The marvel of the 21st century, the iPod, never had it so good. Psychologists are of the opinion that because primarily an iPod delivers music and the human mind is naturally attuned to music, therefore it is an instant hit. But there are other mp3 player devices around, then what makes this device so unique? Market analysts say that the small size of the iPod, its capacity to store thousands of songs, and its ability to use the computer as an alter ego, has contributed to its tremendous sale.

However, market survey agencies pronounce that the popularity of the iPod is mainly due to the strong identification between songs and emotions. When people hear a particular song, they identify it with some emotion, some event of their lives, and they relive those moments of the past. This makes them feel happy, which in turn justifies the amount of money they have spent on purchasing their iPods.

People have gone on record to say things like when they hear romantic songs they are reminded of their ex-girlfriends or pleasant moments. When they hear songs like Bette Midler`s `Wind Beneath My Wings`, they are reminded of their husbands. Stock exchange brokers and traders identify their job and lives with the Frank Sinatra song, `My Way`. Similarly, Linda Ronstadt`s `When Will I Be Loved`, and Peter Frampton`s `I`m in You`, reminds one of the high school dances. This association with emotions makes the iPod a must-have consumer product.

Some iPod users have something more than an intense affair with their mp3 player music devices. Something more like an obsession. It is an on going love story. Sociologists claim that the iPod makes some individual a good societal being, as their frustrations are released by simply listening to their favorite songs. Dramatists affirm that emotional catharsis is superbly performed by iPods. Some medical experts state that mp3 player devices may even eliminate depression and elevate one`s mood.

As music tends to be very personal, it becomes very emotional. So when you listen to the songs stored in your mp3 player device, you tend to get emotional and take a walk down memory lane. Thus, iPod becomes a small, compact memory bank, which you can carry around with you, wherever you go.

The ability of the iPod to rewind your life backwards and hear it, being enacted in lovable musical melodies is perhaps the greatest selling point of this machine. No wonder then that more than 22 million iPods have been sold in a few years only! No wonder then you see people with their music players down the streets, at Harris Teeter while shopping for Cocoa Puffs, while doing stretch ups at Gold`s Gym, or sipping high quality afternoon tea at the Ritz`s. The iPods have become absolutely indispensable, completely irreplaceable, and simply irresistible!

With the iPods now coming with multimedia capabilities, they have become small, personal cinema houses, compact media players to view home videos, or even to show some commercial multimedia applications. Thus, with passing time, the popularity of the device is increasing as it enters new vistas of commerce, arts, and sciences. The iPod has indeed become multifunctional and multifaceted, and has aptly adapted to the needs of changing times. This adaptability is the prime reason why this music player sells so much!

How To Find The Best Digital Camera

It seems that every month, if not every week, different manufacturers are coming up with the latest digital cameras to entice potential clients. And it's just not working for us!

After spending sizeable amount of time at the mall figuring out which is the best digital camera for us, we finally have enough money to buy for that eye-popping, 7 mega pixel, 10x digital zoom, potable, candy colored, up to 512MB expandable memory of super hi-speed SD memory card and not to mention very portable, (that will be the envy of almost everyone we know). We march to the mall armed with our life savings and lotsa pride in ourselves, when we pass by a new display - an eight mega pixel, up to 1G expandable memory, with built it mic and stereo surround, video playback capable, with 22 scenic modes kind-of-camera. And we sigh because the producer of this amazing gadget claims that this is the best digital camera yet out in the market. And so as we always want to have the best, armed with our life savings and a few credit cards, we buy the "best digital camera." But then again, that doesn't last too long, after two months or so, there's another "best digital camera."

And so it confuses us. What makes a digital camera, the best digital camera?

Well, there are certain factors to consider when looking for the "best digital camera" for us.

MEGAPIXELS. One of the most important features of digital camera to make it into the best digital camera category is its mega pixel property. The higher the mega pixels the better the actual photograph will come out. A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera. This means that as you enlarge the picture, you would get more detail and less blurry colors.

LCD SIZE. The best digital camera will always have a large LCD to help you frame your subject without having to squint to the viewfinder. This is also helpful when reviewing your images, some cameras enable touch up and editing features with its LCD. A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher.

ZOOM. Most digital cameras have both digital and optical zoom. A higher optical zoom is always better than a higher digital zoom. Digital cameras are usually furnished with optical of between 3x to 10x. The better the optical zoom, the higher it climbs up to the best digital camera category.

MEMORY CARD. Always make sure that your memory card is the right one for your digital camera. There are different types of memory card like the xD, SD, Flash card and the likes. And these types of memory cards go with certain types of digital cameras. of course memory storage is also up there in choosing the best digital cameras. Choose the size of memory that you need, if you're a photo junkie, you might need more than 32MB. Memory cards can go up to 1G.

The key point to find the best digital camera is to find one that will best fit you and your lifestyle. Don't just buy the latest or the one that claims they are the best digital cameras out in the market. You wouldn't want to buy a DSLR and use it with your home activities or family outing and have to lug it around?! Or you don't want to buy the latest point and shoot camera when you're serious about being a professional photographer. (Of course, you can use this for starters, but if you're not a novice photographer anymore, you wouldn't want to get this kind of camera.)

Actually, the best digital camera is the one that you will enjoy and use. Not the type that you'll just leave rotting in its box or after a few weeks of usage or so, up there in the attic.

Digital Camera: Its Future

Basically a digital camera is a deice use to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It has a built in computer and records the images it captures in an electronic form. Having and operating one does not even require the use of electricity.

Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just took. Just like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the image that you want to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor device that electronically records the light. Remember the built in computer, it comes in here and breaks this information to digital data resulting to all the features of the digital camera.

Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.

A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger

The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges into photosites. Simply putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole image. Both CCD and CMOS do this task using different methods.

When shopping for the best digital camera, take note of these key features.

Image quality. Check the resolution of the camera. The higher the resolution, the more thou will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.

Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the image sensor and incorporate them to make an image.
Power. Always opt for rechargeable batteries, they can always come in handy, plus you don’t waste as much money on the disposable ones.

Options. So you can brag to your friends how good a photographer or artist you are. Or choose the one that gives options that best cater to your lifestyle, so you won’t ever whine how you never get the right pictures.

Memory. If you’re a photo freak, be sure that you have enough memory in your camera to take all the wacky, freaky, funny and just about any photo you can. Think 512MB if you’re a photo junkie and takes pictures of just about anything.

Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is, you don’t want to go running around the whole state or the country looking for a computer that’s compatible with your digital camera, wont you?!

Physical. If you are going to be bringing it everywhere, choose a handy and portable digital camera. This way, it won’t always feel as heavy and bulky as those cameras that you see professional photographers are always dragging on their neck. Don’t they ever get tired of that?!

These are just the basic things you have to look for in a digital camera when you buy one. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.

International Cell Phone Services

If you are one who does a lot of international traveling, then you will want your clients to be able to reach you from wherever you might be in the world. But what are some of the options you have when it comes to maintaining your current level of cell phone (telefone celular) services worldwide? Do you have to buy a new plan? Do you have to pay outrageous rates? Just what is available?

First of all, the country where you live is very important when it comes to international cell phone (telefone celular) services. Most of the countries have one standard in cellular communications known as Global System for Mobile Communications or GSM. However, the United States did not follow the GSM standard and allowed competing wire carriers to develop their own standards. So, if you are coming from the United States and want to get cell phone coverage in another part of the world with your existing equipment, you probably will not be able to do it.

So let’s get back to our options for international cell phone (telefone celular) service. It is important to understand that the key issues to having effective international cell phone service is that you must have a phone that will handle the frequencies plus a service that is compatible within the country you are communicating from. If you have a phone set that handles GSM service, then your phone will be compatible in at least 212 countries worldwide, as far as hardware is concerned. The only other item you will have to be concerned with is the service plan.

The GSM frequencies operate worldwide typically at 900 MHz but more and more the cell phones (telefone celular) are operating at 1800 MHz. There are some GSM phone services in the United States and Canada but they work at 1900 and 850 MHz and therefore are incompatible with the rest of the world. That is why more and more we are starting to see tri-band phones being sold that are compatible with both international and North American GSM frequencies. The Nokia 3220 is a good example as it will handle both the 1800 and 1900 MHz frequency bands.

But what about the international cell phone (telefone celular) service? If you get one of the tri-band phones you can get a SIM card that can be used in multiple countries. These SIM cards are somewhat like pre-paid phone service. You put the card in your GSM-capable phone and have international roaming coverage from wherever the card is valid.

When choosing an international cell phone SIM card for your GSM phone, there are things you should consider when making a decision on which SIM card to buy. First, what is the initial calling credit (how long before you have to recharge)? Of course you should know the rate structure of both the incoming and outgoing calls. Next you should make sure that your phone and SIM card you are purchasing will be valid for the countries you intend to travel.

Since you are not going to be global roaming with your home cell phone (telefone celular) service, you will want to let everyone there know how they can reach you by your new number. You can also change the greeting on the voice mailbox of your regular home cell phone service telling your callers your new access number while you are out of the country.

While you are using SIM cards that will be exchanged or replaced, make sure that you save everything (phone numbers, memos, notes, etc.) into your cell phone (telefone celular) handset and not the SIM card. If you save any information on your SIM card, then the information will be unavailable whenever you exchange for a new card in another country.

China Mobile Phone Step into the World

When the cell phone first appeared on the Chinese market in the late 1980s it cost 10,000-20,000 yuan, and was the size of a brick. Regarded as the ultimate status symbol, it was called the da ge da, meaning very influential person. At that time, sales of mobile phones were under state control, and stocks were limited. Purchasers were required to place an order and make an 80 percent down payment. How things have changed! Mobiles are now available in multiple choices of size, color and function, on request.

Actuality
China has become the world's largest mobile phone manufacturing base and consumer market. In the first quarter of 2008, the total mobile phone shipment in China reached 134 million units, increasing 34.5% year over year. While the subscriber base of mobile services reached 480 million at the end of the first quarter of 2008, which increased approximately 20 million when compared to the statistic data at the end of last year.

Internationalization
With expanding the industrial scale and quickening the pace of innovation, the entire domestic mobile terminal industry begins to step into the world, seeking new markets, technologies, capital and other resources for more development space. To cater to these demands, the IMIE'2007 has invited overseas buyers from 24 countries and regions, including 7 overseas mobile operators and 17 multinational purchasing delegations. Their purchasing lists include HSDPA/GSM/CDMA mobile handsets, PDAs, smart phones and other mobile devices, as well as components and accessories.

Representative Product
When it comes to affordable iPhone clones, Meizu seems to be leading the pack now that they've unveiled the pricing for their M8 cell phone. The 4GB model with built-in camera will go for 0 while the 8GB version will go for 0. The entry-level model (with no camera) will go for only 5 at 4GB and 5 at 8GB. Compare that to the iPhone's 9/9 price and suddenly Meizu's option doesn't look so bad, though it's still an iPhone clone.

Trade Shows

Watch Satellite TV on PC Instantly Using Software

Watching satellite TV on PC using software is a hassle-free experience for TV viewers. This new way of watching your favorite drama serial or LIVE sports channel on your personal computer has ushered in a brand new media era. More people are ditching their old satellite dish, and tuning into their desktop or laptop to watch TV. Read on to find out more about the benefits to watch satellite TV on PC as opposed to the traditional methods.

1. Associated Costs

Are you used to paying monthly subscriptions of more than $30 to service providers for your access? In some cases, you could be footing a larger bill because of some special add-on channels you have subscribed for. It is definitely much cheaper and cost-effective to watch satellite TV on PC because the only cost is the cost of the internet software. It does not even cost you more than one month's subscription at some satellite TV providers.

2. Ease of Installation

It is easy to watch satellite TV on PC. Simply install the software onto your PC and you can start watching channels from all around the globe in a matter of minutes.

How Satellite TV Dethroned The Cable TV

Gone are the days when cable TV was a simple matter of turning the idiot box on and settling down to a baseball or basketball broadcast. With the advent of technology, Satellite TV has come and occupied a premium place in the hearts of the people. The first satellite television signal was relayed from Europe to the Telstar satellite over North America in 1962.

Satellite TV is dominating the US market with its best quality picture, maximum number of channels for the least amount of money and thus awesome value for the money spent.

Earlier the satellite TV was limited to the towns; but now even the farmers and country dwellers could have the entertainment option through the satellite TV. Even the gigantic satellite dish sizes were changed to sleek models and no more installation headaches. The satellite TV has meta-morphsized a lot. Today's satellite dish is sleek and compact , and satellite TV offers strong competition to cable TV.

In fact, the intense rivalry has forced cable TV providers to add extra services like high definition TV signals and movies on demand in an attempt to compete with satellite TV. Unfortunately, the cost increase led to the constant rate hikes in the subscription for viewers and thus operators lose customers. This led to the growth of satellite TV which offers an alternative to all these frustrations.

Let me explain in brief regarding the satellite TV. Satellite TV is a television delivered by way of communications satellite , as compared to conventional terrestrial television and cable television. Satellite TV gives you a clear and comprehensive picture of your best alternative to typical cable TV. Right now, over 45 million people in US subscribe to Satellite TV. Satellite TV is no longer an obscure or exclusive club for people with big wallets. With most retailers offering free installation, you can start enjoying satellite TV for as low as $19.99 a month!

Satellite TV provides the best picture quality and the most channels for the least amount of money. Thus creating the most awesome value for the money spent over entertainment.

Today, there are three major providers of Satellite television: Dish Network, DirecTV and VOOM. Each one offers a large number of channels and several low-cost options for service. In addition to that, they offer freedom from the binding stresses of your local cable company, and that alone is worth it.

The best deals on satellite TV are available from authorized retailers. While your monthly bill will be the same regardless of where you procure your equipment (the providers dictate the monthly cost either way), these authorized retailers offer you a far better selection of promotions, such as free installation and equipment, discounted HDTV dishes and receivers, and free trials of premium channel, and credit towards your first month bill (refund of activation fees).

Now you can watch more channels than your standard antenna could ever provide. You can receive more than 250 stations from favorites like CNN, MTV, HBO, and ESPN, to more obscure options like the Speed Channel, Discovery Wings, and the Love Stories network, Nickelodeon and HGTV, plus plenty of movies, sports, local channels (in many cities) and even HDTV programming. Subscribers also receive more than 30 commercial-free music stations-from Top 40 to Jazz to Classical and everything in-between.

There is a satellite TV channel to suit every imaginable interest. Whether you are into sports, fashion, travel, music or romance, you will find it all, and much, much more, on satellite TV.

Both Dish Network and Direct TV received the highest possible reputation and ratings in almost every category, including reliability, cost, and customer service. In contrast, the major cable companies' scores were not even close.

According to JD Power and Associates, 133,000 consumers nationwide and discovered that they gave both DIRECTV and DISH Network "outstanding" customer service ratings while only two cable providers were found to perform "above or at" the industry average. J.D. Power and Associates ratings are based on research studies that survey a representative sample of owners, they are indicative of what typical buyers may experience. Truly they are based on the opinions of consumers who have actually used or owned the product or service being rated.

When it comes to satellite TV system providers, Dish network Satellite System is the top rated satellite TV system provider. It is known for its delivering unsurpassed customer satisfaction and excellent product quality, all at cost-effective prices.

DISH Network is a direct broadcast satellite (DBS) service that provides satellite television and audio programming to households and businesses in the United States. By the end of the year 2006, there are over 13 million installations of Dish Network. So one can judge the popularity it enjoys in the hearts of Americans.

How Can You Get Maximum From Your Portable Generator

Your portable generator is your only refuge in the case of a power-cut, when there is a great need to keep thing moving and working. To be used as a temporary source of power for emergency after calamity – like, hurricane or tornado - portable generator is a popular option. In such cases, if there is a need for rescue and retrieval, especially during the night, the portable generator can keep machines and lights going for the purpose.

A matter of concern when it comes to a portable generator is that it can be a health hazard to people, if not used properly, more details are located at Hondageneratorstore website. Hence, it is the responsibility of the users to use portable generators in the right way.

Chiefly, there are four main hazards that portable generators can impose:

i) Release of carbon monoxide from the generator’s exhaust

ii) Fires due to improper refueling

iii) Electrocution or shocks due to wrong connections

iv) Loud noise and vibration.

Carbon monoxide is a toxic gas. Its undetectable nature makes it all the more dangerous, as it can lead to death due to suffocation. It is unlike other gases – being colorless and odorless – that it why it is impossible to sense.

Keep your portable generator in places where there is proper ventilation, so as to avoid poisoning due to carbon monoxide. Closed spaces - like a room, basement, or garage – are a complete ‘rule out’, when it comes to placement of portable generator also check out all safety precautions at hondageneratorstore. So are places like windows, doors, or any kind of openings in the house.

If you run the generator indoors, keep in mind that open windows or doors are no guarantee or safety against carbon monoxide build up. In fact, the harmful effects of carbon monoxide can also enter open doors or windows, even if the generator is run outdoors. If anyone experiences symptoms like giddiness, nausea, headache and fatigue, take the person to an open area where he can get fresh air.

Generators, like car engines, get hot when their engines run for a long time, get more details at hondageneratorstore But unlike car engines, generators remain hot for a long period of time, making it impossible for you to refuel them, while running or immediately after they are shut down. The generator needs to be cooled down for a while. Once the temperature is safely low, refueling can be done. Fire can also occur, even before your intention to start refueling it, particularly if your gasoline containers are placed near or beside the generator.

Generators should be considered as ordinary power sources. Since generators do not have safety devices - like circuit breakers and transformers - they can cause harm, more so in case you happen to get electrocuted. Keep every connection clear and clean, to ensure the safety of everyone around. Avoid unnecessary and unsafe connections, as well as tangling ones.

Keep the generator dry, as under no condition should you let it work in the rain. In case it starts raining, use a canopy to cover the generator. Don’t ever attempt to connect any devices when you are barefooted. And under no circumstances should you connect wet electric devices to the generator.

Board-by-Board Optimization

Just as each board type enjoys its own thermal profile in your surface mount oven, each board type also enjoys its own board-wave parameters in your wave machine

The optimal dwell time for that board was found to be 3.6 seconds, in contrast to 2.8 seconds for the first board. As you can see, the “dwell time profiles” of the two boards are different. This process resulted in dramatically lower defect rates for the second board studied (which had also been previously run at 1.0 seconds), although never quite as low as the new baseline which was attained for the first board. This strongly indicates the presence of sources of defects unrelated to dwell time, for example non-optimal immersion depth or design problems.

Immersion Depth

Changing your immersion depth changes your contact length and dwell time. This makes the direct and accurate measurement of immersion depth critical. Your pump speed produces a wave height (although this can diminish as your solder pot empties of solder), but the actual immersion depth of your boards depends on several factors, including solder pot height, how they sit in the fingers, if your fingers are bent, broken or crooked, the angle of your conveyor and whether or not pallets are used.

Yet controlling your immersion depth - measuring it and keeping it consistent - is only one piece of the puzzle. Another is: At which immersion depth is your board quality optimized? This point is illustrated by figure 4. See that the defect rate of the board represented by the blue bars is optimized over a different range (48 mil, or even 36 to 60 mil) than the board represented by the yellow bars (at 24 to 36 mil). So, different board types benefit most from different immersion depths.
Quantifying Cost Benefits

Prior to this study, yield loss was tracked on a monthly basis as a measure of the cost of production failures. Production volume for the board studied was 11,000 per month.

1.) With the implementation of optimal dwell time procedures using the described device, yield loss went from 3.0% (330 boards) to 1.6% (176 boards) in the first month of daily use.

2.) This meant a reduction in yield loss of 154 boards per month. For a 30 day month, this means 5.13 boards per day.

3.) At 0 for the cost of each board, cost reduction based on improved yield loss alone was ,200 per month, which annualizes to 4,400.

4.) That means that the return on investment on the device used in the study was less than five days.

Conclusion: A seemingly small daily improvement in wave solder quality meant fast, very large, measurable monthly and annual cost savings. These figures do not even account for the valuable savings from benefits like reduced rework and field failures, less downtime and increased throughput, each of which in its own right can be more valuable than the rapid savings on yield loss.
