Spread Spectrum Transmitters

By this Notice of Proposed Rule Making (``NPRM''), the Commission proposes to amend its rules regarding the operation of spread spectrum transmission systems in the 902-928 MHz, 2400-2483.5 MHz and 5725-5850 MHz bands. For simplicity, these bands will be referenced in this proposal as 915 MHz, 2450 MHz and 5800 MHz, respectively. The Commission proposes to eliminate the limit on directional gain antennas for spread spectrum transmitters operating in the 5800 MHz band. We are also proposing to reduce, from 50 to 25, the minimum number of channels required for frequency hopping spread spectrum systems operating in the 915 MHZ band. These proposals are in response to Petitions for Rule Making filed by Western Multiplex Corporation (WMC) and Spectralink Corporation (Spectralink). We are also denying a Petition for Rule Making from Symbol Technologies, Inc. (Symbol). Further, the Commission on its own motion proposes a number of amendments to the spread spectrum regulations to clarify the existing regulations, to codify existing policies into the rules, and to update the current definitions. These changes will expand the ability of equipment manufacturers to develop spread spectrum syst
