In today’s 2nd Report and Order, the Commission amended its rules for
general Part 15
unlicensed operations that use wide bandwidths but are not classified as
UWB devices under its
rules. It increased the peak power limits and reduced the unwanted
emission levels for 3
frequency bands that were already available for unlicensed operation:
5925-7250 MHz, 16.2-
17.2 GHz, and 23.12-29 GHz, and indicated that higher peak power limits
in these bands would
facilitate wideband operations such as short range communications,
collision avoidance,
inventory control and tracking systems. The Commission also amended its
measurement
procedures to permit frequency hopped, swept frequency, and gated
systems operating within
these bands to be measured in their normal operating mode.
In light of these changes to the general Part 15 provisions, the
Commission did not make
any major changes to the current UWB technical requirements, indicating
that changes to these
rules at this early stage could be disruptive to current industry
product development efforts. The
Commission made only a minor change to the measurement procedure applied
to gated UWB
vehicular radar systems.
Action by the Commission December 15, 2004, by Second Report and Order
and Second
Memorandum Opinion and Order in ET 98-153 (FCC 04-285). Chairman Powell,
Commissioners Abernathy, Copps, Martin and Adelstein.
From December 24, 2004:
* FCC Permits New Unlicensed UWB Devices *
* ** *The FCC adopted new rules to permit unlicensed wideband devices
in the 6 GHz, 17 GHz and 24 GHz bands. Specifically, the FCC amended
its rules for general Part 15 unlicensed operations that use wide
bandwidths but are not classified as UWB devices under its rules. It
increased the peak power limits and reduced the unwanted emission
levels for 3 frequency bands that were already available for
unlicensed operation: 5925-7250 MHz, 16.2-17.2 GHz, and 23.12-29 GHz,
and indicated that higher peak power limits in these bands would
facilitate wideband operations such as short range communications,
collision avoidance, inventory control and tracking systems. The
Commission also amended its measurement procedures to permit frequency
hopped, swept frequency, and gated systems operating within these
bands to be measured in their normal operating mode.
