a Includes 0.8 dB offset from single-cell tolerance for UL CA.
b Antenna gain above the co-located maximum gain value must not be used when the Wi-Fi module
is fitted unless the Wi-Fi and cellular antennas are separated by more than 20 cm.
c Important: 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. UIP4RF55 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 4RF.
