Max EIRP - CCNA Wireless

rwtodd2007

While reading tonight, theres a chart in the official Cisco Wireless Guide that has both FCC and Cisco Antenna requirements for Point-to-Point environments.

FCC - Transmit Power 30-dBm, Max. Gain 6-dBm for EIRP of 36-dBm

Cisco - Transmit Power 20-dBm, Max. Gain 36-dBm, for EIRP of 56-dBm.

FCC Part 15 says max can be 36-dBm so why would Cisco allow their EIRP to exceed that amount?

FCC imposes a maximum EIRP of 36dBm for Point to MultiPoint transmissions, directional point to point transmissions are allowed a higher EIRP. Not sure what the maximum for point to point is, but the wireless guru at work would know, I'll ask and reply here.
