1.3.3 Setting the reader RF Power
During initial installation, the reader must be properly configured to use the correct RF power. DO NOT
increase the power beyond the recommended power setting as calculated below.
The maximum RF power is determined from antenna gain and antenna cable loss using the formula:
Maximum RF power = 35dBm (3.28W e.i.r.p 2W e.r.p) - Antenna Gain + Cable Loss
For example, if the antenna has a maximum gain of 6 dBi, and the cable has a minimum loss of 1.5 dB, the
maximum RF power that may be set is (35 – 6.0 + 1.5) = 30.5 dBm.
The reader RF Power is set through the
Communication Settings Page
as described on Page107.
