Data Speed of the Wireless Link
By default, the radio of Avaya Wireless Outdoor Router products will transmit at
the highest available transmit rate.
As data transmissions at lower speeds can travel larger distances than
transmissions at the highest transmit rates, the Avaya Wireless Outdoor Routers
allow you to choose a lower data rate to increase the maximum range. For
information about customizing the transmit rate of your Outdoor Router, please
consult the "Avaya Wireless OR Manager - User’s Guide".
To help you to determine the appropriate tuning settings, we have listed the
range values that apply to the various transmit rates in Table 3-1 and Table 3-2.
Determine the Cable Factor
The range value calculations listed in Table 3-1 and Table 3-2 were based on
antenna installations where both antennas were connected to a 6m/20 ft. cable.
■ If this is the case in your situation, the Cable Factor for your installation is
100%.
■ If you are using different cables, you will need to determine the Cable Factor
from Table 3-3 below, to calculate the probable range for your
Avaya Wireless Outdoor Router installation.
Table 3-3 Calculate the Cable Factor
NOTE:
When using Table 3-3 in countries that adhere to the ETSI regulations,
please note that the maximum ranges as listed in Table 3-2 do not
always use cable factor 100%.
