6.4.5.3 Setting RF642A parameters for RF680R/RF685R
Operation within the EU according to DIN EN 302208 V1.4.1
Note
Limitation of the radiated power according to DIN EN 302208 V1.4.1
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 setting a radiated power of up to 2000 mW ERP, an antenna gain of 6 dBi for the RF642A
and the cable loss of the antenna cable (see table (Page 223)), the transmit power of the
reader is correctly configured and the maximum permitted radiated power of the antenna is
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), an RF642A antenna gain of 7 dBi and taking into account the cable loss
associated with the antenna cable (see table (Page 223)), the reader's transmit power is
correctly configured.
Operation in Japan
According to ARIB STD-T107 the antenna must not exceed a radiated power of 500 mW
EIRP (or 27 dBm EIRP).
Operation in the USA, Canada
Note
Limitation of the transmit 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 can
be put into operation, as long as the 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
• Cable loss a
P(dBm) ≤ 30 dBm - (G
