The following steps will enable to you determine the maximum allowable
power setting of the radio:
1. Determine the antenna system gain. To do so, subtract the cable loss
from the antenna gain. For instance, if the antenna gain is 10 dBi and
the cable loss is 3.9 dB, the antenna system gain is 6.1 dB. Note that if
the antenna system gain is 6 dB or less, no power adjustment is
required.
2. Subtract the antenna system gain from 36 dBm, maximum allowable
EIRP. The result is the maximum transmitted power allowed. Based on
the example in step 1, this value is 29.9 dBm.
3. The radio transmit power parameter should be configured to equal or
less than the output power value found in step 2. Set the power output
using the Radio Transmit Power field in the Advanced Configuration
screen (Chapter 3).
The following table provides several antenna system gains and the
corresponding maximum allowable power setting of the radio.
Table 2–2. Antenna system gain versus power output setting

Maximum Power Setting (dB) EIRP (dB)
6 dB or less 30 dB 36 dB
16 dB 20 dB 36 dB

Antenna system gain calculated by subtracting cable loss in dB from antenna gain in dBi. If antenna gain
is rated in dBd, convert to dBi by adding 2.15 dB.
To install the software, the operating system must be running Microsoft®
Windows® 98/NT/2000/XP (English versions). Insert the CD into the
appropriate drive. The CD should automatically start. Follow the
directions as they appear on the screen.
