Transmit Power Control

You can display and modify the radio TX power level on a per node basis

utilizing the HotView™ management software. The maximum power (i.e.,

100%) is a factory-conﬁgured value that is unique to each country of

operation, each channel of operation, and each antenna conﬁguration and

has been determined to be within an authorized limit. This value cannot be

changed. However, using the HotView software, a mesh administrator can

set any node to operate at a reduced percentage of this maximum power

(e.g. 75%, 50%, or 25%). The administrator can restore the HotPort node to

its approved maximum power by setting the power level back to 100%.

Note: You can only adjust the output power in the following increments:

25%, 50%, 75%, and 100%. These adjustments affect the node radio, so

care must be exercised when adjusting on an existing network as the lowered

power level may cause the node to lose connectivity with other mesh nodes.

For example, if the maximum FCC-allowed power output for a certain coun

try, channel, and antenna is 17dBm the settings would be:

100% = 17dBm

75% = 16dBm

50% = 14dBm

25% = 11dBm

Note: Adjusting the power incorrectly could have an adverse effect on proper

mesh operations. If you are not sure what the power should be adjusted

to, it is best to leave it at its default conﬁguration. If you need additional

technical assistance, please contact your Firetide dealer.
