Chapter 5 Cisco Aironet 1250 Series Autonomous Access Point
Channels and Maximum Power Levels
Table 5-6 indicates the channel identifiers, channel center frequencies, and maximum power levels for
each channel allowed by the –P regulatory domain for a 2.4-GHz radio with up to 10-dBi antennas.
5 GHz Band (pre-n IEEE 802.11n)
An improper combination of power level and antenna gain can result in equivalent isotropic radiated
power (EIRP) above the amount allowed per regulatory domain.
Note Dynamic Frequency Selection (DFS) operation and operation from 5500 to 5700 MHz has not been
authorized as required by the rules of the Federal Communications Commission and is not supported in
the -A regulatory domain until authorization is obtained.
