This is from another list -- if anyone here can explain, I'll cross-post on the CYBERTELECOM-List with full attribution. Thanks.

Specifically, the Commission has modified Part >15 of its rules to permit new digital transmission technologies to operate >in the 902-928 MHz (915 MHz), 2400-2483.5 MHz (2.4 GHz) and 5725-5850 MHz >(5.7 GHz) bands under the current rules for spread spectrum systems.

These actions will foster the development of new >products and increase consumer choice. > >Currently, the Part 15 rules permit the operation of DSSS and FHSS systems >on a non-licensed basis. In both techniques, the power density of the >transmitted signal is reduced, which lowers the possibility that the >transmitter will cause interference to other devices operating in the >band. The Commission has determined that because new digital modulation >technologies have spectrum characteristics similar to DSSS systems, they >can operate under the same rules as DSSS devices in the 915 MHz, 2.4 GHz, >and 5.7 GHz bands without posing additional risk of interference. Today's >decision removes the rule that limits systems in these bands to only DSSS >and FHSS technology. > > Additional actions taken today will permit the use of as few as >fifteen hopping channels for FHSS in the 2.4 GHz band. These systems will >be able to use channel bandwidth up to 5 MHz wide, but they must reduce >their output power to125 mW if fewer than 75 hopping channels are used. >This action will allow new FHSS systems to better avoid interference than >today's systems by enabling them to avoid occupied channels. The >Commission also eliminated the processing gain requirement for DSSS >systems, concluding that manufacturers have market-driven incentives to >design products that they can withstand interference from other radio >frequency devices. > >The rule changes adopted in this Second Report and Order will provide >manufacturers flexibility to design and market a more diverse set of >products which are able to operate efficiently in the unlicensed bands. >The rule changes will also allow for greater spectrum sharing in the 2.4 >GHz band by removing regulatory barriers to the introduction of new >non-interfering technologies. > > Action by the Commission May 16, 2002, by Second Report and Order >(FCC 02-151).
