Planning for connectorized units
This section describes factors to be taken into account when planning to use connectorized APs
with external antennas in ePMP networks.
CALCULATING MAXIMUM POWER LEVEL FOR CONNECTORIZED UNITS
If a connectorized ePMP link is to be installed in a country that imposes an EIRP limit in the
selected band, choose an external antenna and RF cable that will not cause the ePMP to exceed the
EIRP limit. To calculate the highest setting of Maximum Power Level that will be permitted, use
this formula:
Maximum Power Level (dBm) = Allowed EIRP (dBm) – Antenna Gain (dBi) + Cable Loss (dB)
Where:
Is:
Maximum Power
Level (dBm)
the highest permissible setting of the Maximum Power Level
attribute in the Step 2: Wireless Configuration page,
Allowed EIRP (dBm)
the EIRP limit allowed by the regulations,
Antenna Gain (dBi)
the gain of the chosen antenna,
Cable Loss (dB)
the loss of the RF cable connecting the AP to the antenna.
As the 2.4 GHz, 5.4 GHz and 5.8 GHz have an operating bandwidth of 5 MHz, 10 MHz, 20 MHz or 40
MHz then the maximum allowed EIRP depends on the operating bandwidth of the radio as shown
in
Table 68 Normal EIRP limits with operating channel bandwidth
