EIRP Limits for the United States and Canada
EX-2.4i EIRP for the USA and Canada
For EX-2.4i models, the maximum EIRP allowed is +52.2 dBm. The maximum conducted power of
the radio is +27 dBm for Mode 1 and +24 dBm for Mode 2. The following formula is used to
determine the output power:
P = 30 – [(G-6)/3] + L
where:
EX-4.9i EIRP for the USA and Canada
For the EX-4.9i models, within the 4940–4990 MHz band, the maximum EIRP allowed is +50dBm.
The maximum output power of the radio shall never exceed +24dBm.
For the EX-4.9i models, the transmit power must be reduced from maximum (+24dBm for 20MHz
BW; +22dBm for 10MHz) by 1 dB for every 1dB that the antenna gain exceeds 26dBi (including
transmission system losses)
EX-5i Series EIRP for the US and Canada
5250–5350 MHz Band
For EX-5i models within the 5250–5350 MHz band, the maximum EIRP is 30 dBm. The maximum
output of the radio is +13 dBm.
P = 30 – G + L
where:
Note: The professional installer is responsible to ensure that RF output power is properly
adjusted to not exceed the regulatory limit.
P = Maximum transmitter output Power of radio, in dBm.
G = Specified gain of antenna, in dBi, from 2400 to 2483.5 MHz.
L = Total transmission system losses of all elements between the radio’s RF connector and the
antenna’s RF connector (all cables, connectors, and lightning suppressors), in dB, as specified
or measured between 2400 and 2483.5 MHz.
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.
