The numbers of subscribers with wireless access to the internet through laptops, personal digital assistants (PDAs), cellular phones, pagers and other wireless devices is rapidly increasing. So this market is growing at a fast rate. In fact, companies solely dedicated to this type of service are starting to appear. Analysts predict that e-commerce will be a key application for wireless inter access. Buying books, trading stock, reserving hotel rooms and renting cars from anywhere will be easy and consumers will demand this type of services.

Technology network used in US today, such as CDMA, TDMA and GSM may be changing. Analysts expect that carriers of these networks will migrate to the use of high-speed data networks such as 2.5G and 3G to give end-users enhanced internet capabilities through wireless devices. Since the transition from the traditional technologies to these faster, third generation technologies is so expensive, carriers in the US have been reluctant to upgrade their networks before they see a real demand for high speed wireless data. However, the strategies group predicts that there will be 9.5 million consumer and business 3G mobile high-speed data subscribes by 2005. Wireless carrier that migrates to 2.5G technology will be able to offer subscribers access to the internet at speeds that are comparable to a wire line ISDN connection or faster. This technology also gives users the capability to access streaming media and websites with sound, pictures and video.

2.5G will allow users to download, upload and send large file from wireless devices without a long wait. 3G technology offers wireless internet access at rates of 384 Kbps or higher. Migration to full 3G offers mobile professionals the ability to access data as if they were connected to their office LAN. 3G will enable the use of wireless multimedia and video applications as well as video conferencing. Remote video monitoring will also be possible. For example, a mobile 3G device will be able to display the various views from several cameras placed around a facility or home. The International Telecommunications Union has approved 3G as a wireless technology standard. This technology is ultimately expected to allow customers to have wireless coverage with access to high data transmission speeds anywhere in the world.
