Standards and deployment issues in wireless data networks

Implementation issues have played a key role on various wireless data network standards. 3G Wireless standard attempted to converge to global broadband wireless data network to serve multimedia applications. Yet the rapidly declining price in existing 2G wireless service, the excessive fees in 3G spectrum licence, and the slow-down in business growth had resulted in delay in the deployment of 3G. Bluetooth technology had been expected to grow rapidly as the low-cost solution for short-range wireless network, but the required price drop was delayed to 2002. The delay in both the long range 3G Wireless Network and the short-range Bluetooth network had created an opportunity for the rapid growth of 802.11b WirelessLAN in 2001. As 802.11b network continues to grow, service operators had also used 2.5G technology to provide wireless data services.
