Author : Roberto SedyciasGlobal positioning system (GPS) is an important tool for any wireless system GPS provides the geographical locations no matter where you are Initially it was developed by the federal government meant to be used in military bases to accurately determine the position of ballistic missile submarines, prior to the launch of those missiles

But in addition to military and surveying exercise, today GPS is used in many commercial purposes It is used for air, land and sea navigation Also used in law enforcement purposes for vehicle tracking GPS tracks any location with the help of interpreting signals received from 3 or more orbiting satellites This tool can also be used to know the weather forecast details

Today, communication devices especially cell phones have become much more technologically advanced and are not restricted to mere means of conversation GPS tracking in cell phone is one of such advance features Before GPS, triangulation technique was used where three cell phone towers were used to determine the approximate location of any particular cell phone But often the finding wasn`t precise However, with the advent of this technology, one can get the accurate location within about five meters The cell phone enabled GPS gives ten times more accurate than triangulation

The compact size, great accuracy and easy mobility feature has made the GPS cell phone an increasingly popular tracking device It enables users to accurately track anyone carrying a compatible mobile device This feature in cell phones has many advantages With cell phone GPS tracking, you won`t ever get lost anywhere Any place can be located efficiently within a short time Business persons can get benefited from this GPS enabled cell phones as they can track all their business matters through the navigation feature of these devices

Another important utility of the cell phone GPS tracking can be in emergency services For Police or Ambulance services, it`s easy to locate the call if dialed from a GPS cell phone That`s why, the FCC legislated that wireless networks to supply location information for 911 calls made from cell phones These calls are known as E911 (enhanced emergency) calls

GPS cell phones are a savoir for tourists who in a new place often face problems while finding monumental locations such as museum, hotel, bars, restaurant, shopping complex But the cell phone GPS tracking feature enable them to track any place they want to visit

Following the aftermath of September 11, the FCC has mandated all service providers to make GPS tracking of cell phone calls possible Hence since 2005, all cells have GPS-track option and the use of it are expected to grow manifolds in coming days because as per one statistics, with in the next three years time, the GPS chipset revenue is expected to more than double to $1 3 billion and the GPRS enabled cell phone revenue is expected to be hitting 550 million units

GPS tracking in cell phone has its own pros and cons No doubt it is useful for keeping track of our loved ones, but there is also danger of infringement of privacy Any compatible cell number and its incoming and outgoing number details can be tracked through these GPS cell phones but by companies who have been authorized license for this

In case you wonder that your calls are being traced, don`t worry, for your actual conversation is not traceable with the GPS phones It only keeps track of what numbers are being called in and dialed out If you don`t want to be tracked, you can simply select the “hide” option on your GPS phone any time to opt out of the service You can have access to portuguese articles about cell phones from page www.polomercantil.com.br/celular.php

Author : Chris CroweMany people are having a very hard time just trying to get by Steady jobs and big paychecks have seemed to disappear But your bills certainly have not disappeared There are many ways for people to cut back on the money that goes out as the amount of money that comes in seems to dwindle down

One of the best ways to cut back on your monthly bills is to sign up for a prepaid cell phone Prepaid phones are popular for several reasons and for these reasons they have become more and more popular over the past year

One reason prepaid offers are an attractive option is that in order to purchase one, you do not have to sign a contract This is a big deal for a lot of people Since you do not have to sign a contract, there are no termination fees that you have to pay in order to stop using the service of the company These fees that you often have to pay are really unfair and can be in the hundreds of dollars This is one big reason many people are going with prepaid cell phone offers

For prepaid models, you never have to undergo a credit check There is no contract involved and no necessary monthly payment, so there is no credit involved Many people do not have the minimum credit necessary to get a phone with some of the larger contract companies But many of the large wireless providers are offering prepaid options

Another reason is that you do not have to pay for the same minutes every single month You pay as you go, which means you only pay for the minutes that you use There are restrictions, limits, time constraints, and expiration dates on minutes for prepaid phones, but if you find the right plan that works for you, then you will most likely save money

It is not just companies like Tracfone, Cricket (Leap Wireless), Boost Mobile, and MetroPCS that offer prepaid cell phones It is companies like Verizon wireless and T-Mobile prepaid T-Mobile is actually quite well known for its prepaid service, but Verizon is one of the biggest advertisers for contract based monthly plans

There is a definite shift toward prepaid phones as the consumer becomes more savvy and realizes that there are other options out there The truth is that many people do not use all of their minutes every month, which means they overpay for their cell phone bills Prepaid gives you more control over the minutes you use and the minutes you need to pay for each month

A good rule of thumb is if you use 300 minutes or less, then you may be better off with prepaid If you are a very heavy cell phone user, you talk to your friends a lot, and like to text, then a contract plan is most likely better Text messages add up very quickly because you not only have to pay to send a text, you pay when you receive one Chris runs a website about T-Mobile prepaid phones.
