Regulatory Considerations for 3.650-3.675 GHz FCC/IC part 90 sub part Z Chap-
RADWIN 2000 User Manual Release 2.6.40 21-8
“Restricted contention protocols can prevent interference only with other devices incorporat-
ing the same or similar protocols. Equipment using a restricted protocol can operate only on
the lower 25 megahertz (3650-3675 MHz)."
Transmission power options
Table 21-1shows the extent of compliance by RADWIN 2000 C products to FCC/IC power
limits, having regards to antenna type and transmission power options.
Higher Transmission Power Options and Restrictions:
Table 21-2 defines the maximum transmission power and EIRP limits for the specified fre-
quency and channel bandwidths.
It specifies the power limits to be used by the operator when assigning center frequencies.
