To: quartersawyer who wrote (114547 ) 2/27/2002 12:14:23 AM From: Rocket Red Respond to of 152472 Star Trek Here we come SPTC Federal regulators gave a tentative go-ahead yesterday for a new wireless technology that would make it possible for home machines to "talk" to one another, for federal agents to locate hidden or lost people behind walls, and for cars to stop automatically before hitting a pedestrian. Start-up companies, the Department of Commerce and analysts hailed the Federal Communications Commission's decision as a victory for consumers and the industry. "It is the biggest technology decision of [Michael] Powell's [FCC] chairmanship, and probably of the Bush administration," said Scott Cleland, an analyst with market-research firm Precursor Group. "This is 'Star Trek' stuff." The FCC approved the use of the new, radar-like technology at very low power levels. Ultra-wideband, as the technology is known, can transmit signals through buildings even at low power, trumping cellular phones in its ability to communicate across long-distances and through thick walls. The FCC is permitting its use in stages; the radio-frequency noise from ultra-wideband devices must be 2,000 times lower than that emitted by a personal computer. If that produces no interference with other systems, higher levels of power may be approved. Although it is still an unproven technology, industry watchers say its commercial applications could be vast. Now that the FCC has approved the use of ultra-wideband, Bruce Watkins's two-year-old firm, Pulse Link Inc., can start manufacturing chips to install in televisions and personal computers that will make it possible to, for example, have cable television without using any cables. "Until now we've been just at the research and development level, but now we can manufacture it," and start selling the product within a year, said Watkins, whose firm is based in San Diego. The technology can also be used in hostage situations to identify individuals or objects concealed in caves, rooms, underground or in the wilderness, experts say. Arriving at a decision yesterday was a long and controversial process for the FCC. Because ultra-wideband employs a range of frequencies already used by wireless phone carriers and various federal agencies, it took the National Telecommunications Information Administration (NTIA) 3 1/2 years to negotiate a compromise that would ensure ultra-wideband transmission would not interfere with existing cellular and security systems, including the global positioning system. The new ultra-wideband won't interfere with other devices, nor will it interfere with existing systems, said Michael Gallagher, deputy director of the NTIA. Verizon Wireless, the U.S.'s largest cellular carrier, initially expressed concern that ultra-wideband would interfere with its emergency 911 calling systems, but is tentatively supporting the commission's decision, spokesman Jeffrey Nelson said. The new technology will transmit signals in the 3.1 gigahertz to 10.6 gigahertz range, as well as the 24 gigahertz spectrum, said Julius Knapp, deputy chief of the office of engineering and technology at the FCC. At the levels the FCC has approved, there is almost no chance that devices using ultra-wideband technology will interfere with any systems, he said.
