Operating Range - TBD
Each regulatory region limits the equivalent isotropic radiated power (EIRP) that can be supported
within their region. This restricts the bridge output power that can be used with the bridge antennas and
affects the resulting operating range of the bridge.
Table C-2 and Table C-3 provide the calculated maximum operating ranges for IEEE 802.11b and IEEE
801.11g data rates. The calculations are based on 99.965% link availability.
