Note: The FCC and IC have a strict EIRP limit in Band 30 for mobile and portable stations in order to
protect adjacent satellite radio, aeronautical mobile telemetry, and deep space network operations.
Mobile and portable stations must not have antenna gain exceeding 1 dBi in Band 30. Additionally,
both the FCC and IC prohibit the use of external vehicle-mounted antennas for mobile and portable
stations in this band.
Fixed stations may use antennas with higher gain in Band 30 due to relaxed EIRP limits. EM7690
modules used as fixed subscriber stations in Canada or fixed customer premises equipment (CPE)
stations in the United States may have an antenna gain up to 10 dBi in Band 30, however, the use
of outdoor antennas or outdoor station installations are prohibited except if professionally installed
in locations that are at least 20 meters from roadways or in locations where it can be shown that the
ground power level of -44 dBm per 5 MHz in the bands 2305–2315 MHz and 2350–2360 MHz or
-55 dBm per 5 MHz in the bands 2315–2320 MHz and 2345–2350 MHz will not be exceeded at the
nearest roadway. For the purposes of this notice, a roadway includes a highway, street, avenue,
parkway, driveway, square, place, bridge, viaduct or trestle, any part of which is intended for use by
the general public for the passage of vehicles.
Mobile carriers often have limits on total radiated power (TRP), which requires an efficient antenna.
The end product with an embedded module must output sufficient power to meet the TRP
requirement but not too much to exceed FCC/IC's EIRP limit. If you need assistance in meeting this
requirement, please contact Sierra Wireless.
