In today's day and age, wireless cell phones have almost become a necessity. Not only do they provide easy mobile communications, but you can talk to virtually anyone from anywhere in the world. As profuse as they are, do you actually know what a wireless cell phone is? A wireless cell is basically very sophisticated radios with a low-power transmitter inside. Companies divide cities into small cells, about ten square miles per cell, and the phones ring into a central base station which answers back on whether service is available and what frequency to use. These super two-way radios are what we call a wireless phone. Since a wireless phone (sometimes called a cell phone or a mobile phone) constantly changes which cell it's working within, these phones have amazing range. Now, a wireless cell phone works on either analog or digital technology. Analog means taking an audio or visual signal and translating it into electronic pulses. Size restrictions limit the amount of data an analog signal can carry. Generally, analog products are cheaper than digital, but analog wireless phones are quickly becoming obsolete, being replaced by the superior digital technology. Digital wireless phones differ in that the signal is translated into binary "1"s and "0"s rather than electronic pulses. This binary code gets read and reassembled by the receiving phone. Having a simpler code means less errors and better clarity in the signal. Digital signals can also carry more information. Today, there are so many wireless phones that it's hard to know where to begin when buying one. You can get features like Internet access, voice mail, paging, text messaging, movie capabilities, and MP3 abilities. How should you narrow down your choices?
