6.5.5.2
RF642A parameter assignment
Depending on the country or region in which the antenna is being operated, it is subject to
regional limitations with respect to the radiated power.
Limitations in the EU, EFTA, or Turkey
Note
Limitation of the radiated power according to EN 302 208 V1.4.1 (ETSI)
RF600 systems that are put into operation in the EU, EFTA or Turkey must not exceed the
following radiated power with an RF642A antenna:
•
2000 mW ERP (or 33 dBm ERP)
Converted into EIRP: 3250 mW EIRP (or 35 dBm EIRP)
Make the following settings to ensure that the maximum permitted radiated power of the
antenna is not exceeded:
●
Antenna gain: 6 dBi
●
Radiated power: ≤ 2000
mW ERP (or 33 dBm ERP)
Converted into EIRP: ≤ 3250
mW EIRP (or 35 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 RF642A 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: ≤ 7
dBi
●
Cable loss a
k
(dB): ≥ 1
dB
P (dBm) ≤ 30
dBm - (G
i
- 6 dBi) + a
k
