Within the 5250–5350 MHz band, the maximum transmit power with respect to FCC (USA)
EIRP regulations is determined using the following equation:
P = 30 – G + L
where:
P
= Maximum transmitter output power of radio, in dBm
G
= Specified gain of antenna, in dBi, from 5250 to 5350 MHz
L
= Total transmission system losses of all elements between the radio’s RF
connector and the antenna’s RF connector (all cables, connectors,
lightning suppressors), in dB, as specified or measured between 5250
and 5350 MHz
For the 5250–5350 MHz band, the maximum EIRP allowed for this device is 30dBm. The
maximum output power of the radio shall never 13dBm.
The professional installer is responsible to ensure that RF output power is properly adjusted so
that it does not exceed the regulatory limit of these conditions.
ETSI Compliance – EIRP limits
For the EX-5r family, a +30dBm EIRP limit applies for operation in the 5250-5350 MHz or
5470-5725 MHz bands. Adjust the output power in accordance with the following formula:
P = 30 – G + L
where:
P
= Maximum transmitter output power of radio, in dBm
G
= Specified gain of antenna, in dBi within the operational band
L
= Total transmission system losses of all elements between the radio’s RF
connector and the antenna’s RF connector (all cables, connectors,
lightning suppressors), in dB, as specified or measured in the operational
band
For the EX-5r family, operation in the 5725-5850 MHz band, using a 10 MHz BW setting
(shown as 8MHz in the GUI), a +33dBm EIRP limit applies. Using the same definitions as
above, set the transmitter according to this equation:
P = 33 – G + L
