Widens Radio Spectrum for Wireless Networks By LISA GUERNSEY "In a move that may stimulate development of wireless products for the home, the Federal Communications Commission announced yesterday that it had eased restrictions on part of the radio spectrum. The rule change affects the 2.4-gigahertz band, an area used by companies that produce wireless local-area networks, or LAN's. Such networks enable people to transmit data from, say, a laptop computer to a desktop computer -- or from either to a printer -- without wires. They have been adopted by office complexes, college campuses and, to a lesser extent, consumers at home. Proponents have argued that opening the spectrum will give rise to consumer products that wirelessly transmit large amounts of data, like streaming video and digital music. For example, it may enable someone to send music from a desktop computer to a laptop, or to use a cordless phone to pick up a call that has come in over the Internet. "The rule change has given us everything we need to develop these next-generation wireless devices," said Ben Manny, chairman of the HomeRF Working Group, a coalition of technology companies that asked the F.C.C. two years ago to relax its restrictions. Among the members of the Home RF group are Compaq; Intel; Proxim, a wireless LAN company in Sunnyvale, Calif.; and Siemens, which has developed cordless phones that use the 2.4-gigahertz band. From a technical standpoint, the ruling gives new muscle to a radio-signal technique called frequency hopping. For years, proponents of frequency hopping -- who include members of the HomeRF group -- have squared off with engineers who favor a different technique, called direct sequence. nytimes.com - Fred
