Follow the steps below to configure the Power Output Level:
9
Connect to the transceiver’s Web page (See the FGRPlusRE User Manual for further
instructions).
9
Click the “Radio Setup” Link.
9
Choose an appropriate setting in “Transmit Power”, as defined from the previous tables.
9
Click the “Save Changes” button. After the page refreshes, click the “Reboot” button and
wait for the transceiver to restart.
6.
Repeat the steps above for each transceiver in the network.
NOTE:
Please, be advised that antennas other than listed in this section can potentially be
used with the transceiver provided that:
•
these antennas are of a similar type to the listed above;
•
antenna gain does not exceed 8.15 dBi for omni-directional and 12.15 dBi for
directional antennas
•
overall system EIRP does not exceed 36 dBm.
WARNING: Any antenna other than listed in this section needs to be approved by
FreeWave Technologies before its use to assure that the transceiver in
combination with the new antenna meets FCC requirements.
B. Transceiver Location
Placement of the FreeWave transceiver is likely to have a significant impact on its performance.
In general, the rule of thumb with FreeWave is that the higher the placement of the antenna the
better the communication link - height is everything! In practice you should also place the
transceiver away from computers, telephones, answering machines, and other similar equipment.
To improve the data link, FreeWave Technologies offers directional and omni-directional
antennas with cable lengths ranging from 3 to 200 feet.
