While wired based LAN solutions have saturated the industry, wireless solutions are on the rise. The technology is fairly new by most standards, and it is considered "the most promising" technology for the future my many important industry leaders. It will allow countries/states to defer from rewiring their land based communications structure to support DSL and other high bandwidth solutions. All the while, allowing them to come to grips with the need for the technological future demanding high bandwidth communications.
Long range solutions (ie: WIPS) are still in their initial release, while short range ones, 802.11b and to a lesser extent 802.11a, are becoming more and more popular. 802.11b is familiar to many as one of the first generation WAN solution, supplying a theoretical maximum bandwidth of 11Mbps. It uses a 2.4GHz frequency spectrum, which inherently is resistant to weather conditions. New to the mix is 802.11a, which utilizes the 5GHz spectrum, and provides a theoretical maximum bandwidth yield of 54Mbps.
