Backhaul Maximum Tx Power
The maximum transmit power that you can select is limited by product specifications, the number of channels in
use, and maximum EIRP limits.
Maximum Transmitter Power
Mimosa Backhaul radios are capable of transmitting at the power levels in the table below. With the B5 and B5c,
total power can be divided equally (preferred) or unequally (if necessary) between the two channels. Once power is
selected for a particular channel, it is then divided equally between H and V chains.

* With the B5/B5c, single channel mode has a 3 dB advantage over dual channel mode. This is because
two channels (four chains) are combined internally with the same frequency and phase.

Maximum EIRP Limits (5 GHz)
Local laws may restrict maximum EIRP for certain frequency ranges. The chart below shows restrictions in the
United States.
The equations for calculating the maximum Tx power for each band are the following:
One Channel:
Max Tx Power (dBm) = EIRP limit (dBm) - Antenna Gain (dBi)
