Fueling the increased interest in Wireless Local Area Networks (WLANs) is the relative and growing ease of availability of wireless Internet access for notebook computers, handhelds, such as the Palm and iPAQ's, and the increasingly common use of wireless networks in the home and office. To take advantage of the tremendous growth rate that is being experienced in Wireless Technologies, service providers have been fiercely competing to increase market share and build a customer base, while manufacturers such as Nokia, Ericsson, and Motorola are creating new user interfaces and feature sets on their telephones enabling Mobile Internet access.
