Adjusting Tx Output Power

Adjusting Tx Output Power
Use the following formula in combination with the table of EIRP limits in US and EU countries to calculate system transmit
power (based on EIRP limits) of these countries:
Tx Power (dBm) = EIRP Limit (dBm) + FL (dB) – G (dB)
where:
Tx Power = Output power measured at the antenna input
EIRP Limit = EIRP limits specified below
FL = Feeder loss including loss of connectors
G = Antenna Gain
Frequency (GHz)
2.4 - 2.4835
5.15 - 5.25
5.25 - 5.35
5.47 - 5.725
5.725 - 5.850

Antenna Types and Maximum Gain

For devices using external antennas, professional installers should select only the antenna types listed in the following
table, with gain not exceeding the listed maximum gain for each type.
