When Martin Cooper invented the cell phone, the first handheld mobile phone, it was a dream he had conceived come true. After Bell Labs, an arm of ATT, had made the statement that they were the only ones technically capable and with the money to take over the personal communications business, Martin Cooper and his staff at Motorola took up the challenge. His dream was for a handheld personal communications phone. On April 3, 1973 Cooper actually stood on a street corner and using cell technology, a base station and one portable phone, called his competition and told them that he had beaten them. That he was actually calling them with a handheld wireless phone standing on the street, a far cry from the first telephone invented but just as momentous. Little did those observing the process or passing by that corner realize the result this invention would have on the future. That a personal cell phone in almost everyone’s possession would be the norm. I can remember, in 2005 while visiting Washington DC we were approached by a panhandler begging for change and his cell phone started ringing. 2009 video’s show the new first lady of The United States serving in a kitchen for the homeless and it shows a homeless man in line talking on a cell phone. The question may be, if he is homeless where do they send his bill? But the reality is that we depend on them to extents never dreamed. With modern small business phone systems that works in a many unique ways. Taking your traditional phone and processing it through the Internet and redirecting it in as many directions as needed. They will even forward to your cell phone to send your business calls to you. What you do is go online you set up the various extinctions that you need and direct them to each associate. The callers will never know the difference even if you elect to transfer different lines to associates cell phones across the country. Before the invention of the first cell phone those who wanted to have a wireless communication used a radio device in their car with a top mounted antenna receiving analog signals. These calls were routed through an operator and used mobile radio technology. These mobile units were usually hard wired into the car, hence the slang terminology “car phone”. This technology advanced into “bag phones” which could be carried and were plugged into the cigarette lighter for power. The cell phone theory is based of the idea of frequency reuse through the cells. For instance a city is divided into small areas “cells” and the towers which transmit and receive are pointed to cover all of the cell possible. Frequency reuse is a technique where one cell works on the previous cell frequency. The calls are handed off when one goes into a new cell from the last without any interruption in service. In this concept of “cells” the service provider company sets towers and stations that cover a hexagon shaped area. The correct positioning of the cell towers provides minimal dead areas of coverage. Each cell is connected to another cell and forms a network providing a smooth transmission coverage. All of these small cells are controlled by a main network provider where the information or call is handed off to another area or service provider as we travel. When we call a person or retrieve information the signal is sent the closest cell and is routed to the nearest cell of the caller receiving the call or the sender of information. This is an almost instant process. The unique part of newer cell phone technology is that the electromagnetic waves do not require a line of sight for communications. The cell waves will transmit through many obstacles which even allows us to speak inside the buildings and automobiles without auxiliary antennas. In the 1980s analog transmission was the normal cell network. These systems later became known as the first generation 1G mobile phones. In the 1900s second-generation 2G phone systems were introduced. The development of 2G systems allowed much smaller phones. With these technological improvements, advanced batteries, more energy-efficient electronics and the increasing density of cell sites being built the cell phone craze boomed. With the 2G systems also came the person to person text messaging craze. In 2001 3G systems were introduced allowing higher data rates and many new multimedia services. With a 3G system you can actually search the web on your cell phone, a vast improvement from the first invented cell phone. Cell phones have almost become the mainstay of communications, we even have to register them on the national do not call directory to protect our usage times.
