Single Standards Losing Out to Dual-Band - Ed Sutherland, 80211-Planet
Behind headlines trumpeting unexpectedly strong demand for Wi-Fi chips is a potentially troubling trend. The bedrock of wireless networking, plus its presumed successor, may quickly be on the way out. "802.11a has reached a dead end," says Will Strauss, analyst for the Tempe, AZ-based Forward Concepts research firm.... The 802.11a standard differs from the more widely known 802.11b specification.... Strauss believes 802.11g, with its 54Mbps capability, will take the top spot. The new standard, set for final approval in 2003, will work in the 2.4GHz band. The 2.4GHz band is favored "since it can penetrate walls and has greater distance," requiring fewer access points, according to Strauss. 802.11g is also backwards compatible with the ubiquitous 802.11b.
