Make the following settings to ensure that the maximum permitted radiated power of the
antenna is not exceeded:
●
Antenna gain: 4 dBi (or 7 dBiC)
●
Radiated power: ≤ 1360
mW ERP (or 31.35 dBm ERP)
Converted into EIRP: ≤ 2240
mW EIRP (or 33.5 dBm EIRP)
●
Use of cable loss associated with the antenna cable.
Limitations in the USA and Canada
Note
Limitation of the radiated power (FCC)
RF600 systems that are put into operation in the USA and Canada must not exceed the
following radiated power with an RF640A antenna:
•
4000 mW EIRP (or 36 dBm EIRP)
Make the following settings to ensure that the maximum permitted radiated power of the
antenna is not exceeded:
●
Conducted power P (dBm) of the RF600 reader: < 30 dBm
●
Antenna gain G
i
(dBi) in the FCC frequency band: ≤ 4.3
dBi
●
Cable loss a
