Invention of Cellular Phones

Introduction

Researchers first developed ideas as to the possibility of creating mobile phones that used "cells" that would identify a user in whatever specific region he or she was initiating the call from.

1947 was a big year for what was to become the cell phone industry. That was the time when researchers thought of the idea of cellular phone. Later that same year, the FCC (or, the Federal Communications Commission) decided to open up separate radio frequencies to be available for mobile calling.

Finally, in 1968, companies such as AT&T and Bell Labs proposed new methods of incorporating the cellular phone system. The companies' ideas were based on a concept of many small cellular towers that would handle phone calls for a certain region. When users moved from one region to another, service be transferred to a closer tower. With this development in place, AT&T and Bell Labs began testing the phones for public use.

In 1977 Public cell phone testing began. The first trials began in Chicago and eventually other cell phone trials appeared in the Washington D.C. and Baltimore area. Another separate company in Japan began testing cellular phone service in 1979.

And the journey that started in 1947 is still not completed with the time cellular phone is being evaluated according to the necessities of people and need of time.

It was clear that something needed to be done about eventual overcrowding of cell phone frequencies. There were already more than a million cell phone subscribers. The FCC again came up with a solution i.e. allow companies to research different technologies that could somehow free the cell phone airways. Companies then began developing new alternatives to the current system.

The year 1988 changed many of the technologies that had become standard in the past. The Cellular Technology Industry Association was created to set realistic goals for cellular phone providers and research new applications for cell phone development. The Telecommunications Industry Association with the creation of the TDMA Interim Standard 54, in 1991, set a new standard. Since then, three new technologies have evolved into industry standards for cell phone telecommunications:

1) TDMA IS-136, 2) CDMA IS-95, 3) GSM.

The first two, TDMA and CDMA, are both in widespread use in the U.S.A today. GSM became the standard in Europe but has yet to be used as frequently as the TDMA and CDMA. However, this will almost definitely change in the future, as more companies embrace this newer technology

Public Reception and Implementation of Cell Phone

Cellular/mobile phones are everywhere and their utility is growing. Cellular/mobile phone benefits from the creativity and enthusiasm of entrepreneurs to bring life to the market. It is not only the technology, but also a multitude of consumer and business issues, which will decide how quickly and widely next-generation wireless services are deployed.

It is getting a warm reception for various reasons in business, technology and marketing besides it links people with each other; they can have important conversation anywhere and at any time, as it is handy ...
