This article offers ideas on deployment strategies for Wireless Fidelity (Wi-Fi). The 802.11b wireless LAN standard offers maximum range up to 11 megabyte per second (Mbps), more than enough bandwidth for single-client users. Two technologies are available that offer up to five times the raw data rate or 54 Mbps. One is 802.11g, which operates on the same 2.4-gigahertz (GHz) frequency band as 802.11b and is backward compatible with the older, lower-bandwidth technology. The other alternative, 802.11a, occupies frequencies in the 5-GHz band. It offers less range of coverage than either 802.11b or 802.11g but offers up to 12 non-overlapping channels, compared to three for 802.11b and 802.11g--so it can handle far more traffic than its 2.4-GHz counterparts. The combination of short range and capacity for high-volume traffic makes 802.11a well suited for confined, high-traffic areas like crowded conference rooms and high-bandwidth applications like streaming media. The longer range for 802.11g is more appropriate for larger areas and, because of its compatibility with 802.11b, will function at hot spots, many of which are outfitted with the older standard. An important consideration when developing a wireless network is understanding the Wi-Fi security features built into new mobile clients.
