WavePoint 10e
Transmit Power Settings
The Transmit Power parameter is the output power of the transceiver.
Important: The information in this section describes the FCC maximum Equivalent
Isotropically Radiated Power (EIRP) regulations.
The transceiver output power level must be set to satisfy the maximum requirements
in the country the WavePoint 10e is installed in.
The installer is responsible for ensuring that an installation is within EIRP emission
limits.
When setting up the network, consider the power gain that an antenna may add and the power loss
through cabling. Adjust the Transmit Power on the transceiver so it does NOT exceed the
maximum EIRP for the regulating body where WavePoint 10e is installed. Use the tables to
determine the correct Transmit Power parameter setting for each transceiver in the network.
When calculating the power gain, use Equation 1 to determine the total output power at the
antenna.
Transceiver Output Losses + Antenna Gain = Output Antenna Power
Equation 1
Note: Loss calculations should include cable, connectors, surge protectors, etc.
RF Loss
Cable losses for high frequency systems are one of the main losses to consider in Equation 1.
This table shows the RF loss at various cable lengths.
Example: Using the information in the table, a cable as short as 25 feet can have an
attenuation of almost 1dB.
