Parameterization of RF642A for RF670R
Operation within the EU, EFTA, or Turkey
NOTICE
Limitation of the radiated power according to EN 302 208 V1.3.1
RF600 systems that are put into operation within the EU, EFTA, or Turkey (ETSI) can be operated with an RF642A
antenna with a maximum radiated power of 2000 mW ERP (or 33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP).
By adjusting the radiated power of up to 2000 mW ERP (or 33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP), the RF642A
antenna gain of 6 dBi and the cable loss associated with the antenna cable (see table (Page 3)), the radiated power of the
reader is correctly configured and the radiated power at the antenna is thus not exceeded.
Operation in China
By setting a max. radiated power of 2000 mW ERP (or 33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP), the RF642A antenna
gain of 7 dBi and the cable loss associated with the antenna cable (see table (Page 3)), the radiated power is correctly
configured in the reader.
Operation in the USA, Canada
NOTICE
Limitation of the radiated power to 4000 mW EIRP (36 dBm EIRP) with an antenna gain of 7 dBi
The antenna must be commissioned by qualified personnel. Antennas with a gain >6 dBi may be commissioned, as long as
the effective radiated power of 4000 mW EIRP (36 dBm EIRP) is not exceeded.
To comply with FCC and IC-FCB requirements, the system must satisfy the following relation:
● Conducted power P dBm of the RF600 reader (<30 dBm)
● Antenna gain G dBi in the FCC frequency band (≤ 7 dBi)
i
● Cable loss a dB (≥ 1 dB)
k
P(dBm) ≤ 30 dBm - (G - 6 dBi) + a
