Using VOIP Instead Of Cell Phone by Ryan Arsendatama

VOIP offers so many benefits, primary of which is tremendous savings in the monthly phone bills. But the question that many ask is will people end up using VOIP instead of cell phones? While nobody can deny that cell phones are indeed extremely useful as is proved by the near total market penetration of the cell phone industry, yet VOIP mobiles can indeed cut telephone costs immensely.

Many people get portability with their VOIP service as they may fix their adaptor in anyplace that has a broadband access and make calls. But as the service is dependant on the reliability and the quality of the internet connection, it is rather a drawback.

Many wonder if there is a viable market for wi-fi VOIP phones. Indeed there will be many who would welcome this on account of the obvious reason, saving nearly 50% on the monthly phone bill. Many cell phone companies have addressed the situation by producing dual-mode phones that can be used as regular cell phones which can seamlessly convert into a Wi-Fi VOIP phone too.

Wi-Fi VOIP is enabled within wireless networks that are activated by what is known as a “hotspot”. A hotspot is an area where you find an access point to establish the connection to the network. Mobile users can pick up signals from hotspot to hotspot as they travel within the various network access points.

Some firms have gone ahead and produced completely VOIP mobile phones. This must be welcome news to customers as mobile phone call minutes will definitely become more pocket friendly with mobile VOIP services. This is because they use free radio spectrum and internet instead of investing in large expensive towers, thus they cost less. The reason why many wireless carriers are afraid to venture into wi-fi VOIP is that their landline service will suffer.

VOIP mobile phones are relatively inexpensive to use as other products of VOIP technology. It is technically cheaper to submit audio as data packets over the Internet with less bandwidth. The compression technology is improving so the voice quality is becoming better with less noises or intrusions.

About 200 US cities have made it clear that they will introduce many wi-fi Hotspots free of charge. There are some concerns that wi-fi may replace broadband and traditional phone line services. Well, when that day comes, the customers will benefit getting not only extremely affordable rates but quality service too, that is why they may opt for using VOIP instead of cell phones.

What Makes A GPS Cell Phone
By [http://ezinearticles.com/?expert=Peter_Boston]Peter Boston

What makes a cell phone a GPS cell phone? The first requirement is a GPS receiver. GPS signals originate simultaneously from three to twelve satellites orbiting about 11,000 nautical miles above the earth. The GPS receiver and software sort out the signals from the different satellites and pinpoint the receiver’s location on the surface of the earth to within a few yards, sometimes closer.

More and more cell phones are manufactured with GPS receivers built into the handset. Cell phones without built-in GPS receivers can still become a GPS cell phone by connecting with a separate GPS receiver through a USB or serial port or by a wireless Bluetooth connection. Bluetooth is a specification for wireless, short-range communication of voice and data between two devices.

Both methods can provide turn-by-turn driving instructions, often with voice and illustrated maps that show your location on the cell phone screen. The built-in GPS receiver method is more convenient. There are no wires or devices to connect and there is nothing to download from your desktop. Attach your GPS enabled cell phone to the windshield holder or pull it out of your pocket if you are on foot, push a few buttons and off you go.

You will, however, need a special cellular plan with your cell phone service company, and you may or may not also need to subscribe to their data service. The usual cost is between $10 and $25 per month, but that can vary up or down with usage. Sprint/Nextel and Verizon provide GPS cell phone service with different features.

In addition to convenience, another advantage to a cell phone GPS plan is greater accuracy and fewer lost signals from overhead obstructions. The phone uses a signal from the cell phone tower to correct or enhance the satellite signal. This wireless assisted GPS, or enhanced GPS, can sometimes work inside buildings or under heavy forest canopy, both of which are terminal to line of sight satellite signals. A disadvantage with the cellular plan is that your GPS will work only in places that you can get cellular telephone service.

If you use a separate GPS receiver that connects to your cell phone then you will continue to receive GPS signals regardless of the availability of cellular service so long as your receiver and the satellites can see each other.

Separate GPS receivers usually come bundled with software on a SD or similar card that you insert into a slot on the phone. The software has the maps that display on your cell phone screen. You can continue to receive cell phone calls or connect to the internet with your cell phone while the GPS is working, assuming of course that you have the proper subscriptions for doing so.
The separate GPS receiver method avoids monthly plan fees but you will have to balance that against the cost of the GPS receiver and software, which is from $100 and up depending on the bells and whistles you want to add.

If you live in an area with good cell phone service, and you are a non-technical person, or your are buying GPS for somebody who would never read a manual, then the Sprint/Nextel and Verizon cellular GPS plans are a good choice. When purchased as part of cellular plan the cost of a GPS enabled smartphone is not much different than a regular handset, and $10 – $25 per month is not unreasonable for the service.
