FCC boosts power limit for outdoor unlicensed 60 GHz links

Sunday, August 11th, 2013

The FCC has adopted a Report and Order that raises the power limit for outdoor links operating in the 57-64 GHz band on an unlicensed basis. The average equivalent isotropically radiated power (EIRP) limit is raised from 40 dBm (10 watts) to a maximum of 82 dBm (158,489 watts) depending on how high the antenna gain is. The peak power limit is 3 dB higher. The new power limit is comparable to others the FCC has in the fixed microwave services.This increase is expected to enable higher-capacity outdoor links extending to about one mile. Connection of buildings on a campus is one application, as is connections of small cells within a 4G macrocell. In addition to higher power limits, the FCC also changed the way 60 GHz emissions are specified for consistency with other rules, and it eliminated the need for certain 60 GHz devices to transmit an identifier.
