Cell Phones in USA

Changes came in the plans of the then Federal Government in the year 2000, relating to the US cellular market. In September of the same year, the plan to auction spectrum used by the U.S. Department of Defense to the cellular operators, was postponed by three years. Before this, the FCC ruled that fixed wireless companies do not have to give up the allotted frequency spectrum in order to accommodate high-speed mobile services. In November same year, FCC reversed its ruling, stopping the limitations of the amount of frequency that operator can have.

To meet the competition brought into the cellular market, companies started to prepare to offer various contents in their respective services. Verizon Wireless offered services based on Code Division Multiple Access (CDMA) and claimed that the users would be experiencing a considerable growth in speeds of 40kbits/second to 60kbit/second, on an average. Verizon is a joint venture between Verizon Communications and Vodafone Group Plc.

Cingular Wireless started a strategic plan to introduce General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE) by the year 2004, where the GPRS will offer data speeds up-to 177kbits/second. At the initial stages the users were able to use 40Kbits/second. EDGE offered a greater speed of up-to 470 kbit/second, although the consumers could only have a speed of 100 kilobits/second on average. Cingular has been formed out of a joint venture between BellSouth Corp. and SBC Communications Inc. As per the Global mobile Suppliers Association (GSA), there were 139 commercial GSM/EDGE networks in 78 countries. This is out of a total of 192 EDGE deployments in 102 countries. As far as the country-wise break-up, there are 59 EDGE network in Europe, 45 in the Americas and Caribbean, 21 in Asia, and 14 in Africa and the Middle East.

AT&T Wireless would be deploying GPRS in 40% of its network in the year 2001. The company had planned to offer the service nationally by the end of 2002. AT&T would go on to deploy EDGE nationwide by the end of the year 2002, achieving this through software upgrades. The company would go on to start the implementation of Wideband Code Division Multiple Access (WCDMA) in the year 2003 and complete the deployment in the year 2004. At this time the company could only roll out the service in 80 percent of its markets.
