The challenge of Wi-Fi roaming

Wi-Fi, consisting of the IEEE 802.11a, 802.11b, and 802.11g technologies, has proven to be a fast wireless networking approach that is relatively easy and inexpensive to implement. Companies are working on a variety of approaches to extend Wi-Fi's capabilities, appeal, and potential for generating income. Industry observers say more people would use the technology more often if they could roam among networks, working with one carrier in numerous locations. Carriers would also support Wi-Fi roaming because it would extend the reach of their service and attract more customers.
