Parameter Settings Of Rf640A For Rf640R/Rf670R - Siemens Simatic RF600 System Manual

Operation in China
The national approval for RF600 systems in China means a restriction to 2000 mW ERP (or
33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP). The possible combination of antenna gain,
cable loss, and max. 500 mW radiated power of the RF630R reader means it is not possible
to exceed 2000 mW ERP (or 33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP).
Operation in the USA, Canada
Note
Limitation of the radiated power to 4000 mW EIRP (36 dBm EIRP)
To meet the FCC and IC-FCB requirements, the radiated power may not exceed 4000 mW
EIRP (36 dBm EIRP). Therefore 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

Parameter settings of RF640A for RF640R/RF670R

Operation within the EU, EFTA, or Turkey 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 RF640A antenna with a maximum radiated power of up to 2000 mW ERP
(or 33 dBm ERP, 3250 mW EIRP, 35 dBm EIRP).
By setting the radiated power of up to 1300 mW ERP (or 31.15 dBm ERP, 2140 mW EIRP,
33.3 dBm EIRP), an RF640A antenna gain of 4 dBi (7 dBic) and taking into account the
cable loss associated with the antenna cable (see table), the radiated power of the reader is
correctly configured and the radiated power at the antenna is not exceeded.
Operation in China
By setting a max. radiated power of 1300 mW ERP (or 31.15 dBm ERP, 2140 mW EIRP,
33.3 dBm EIRP), the RF640A antenna gain of 4.3 dBi (7.3 dBic) and the cable loss
associated with the antenna cable (see table), the radiated power of the reader is correctly
configured.
