Setting Rf620A Parameters For Rf650R/Rf680R/Rf685R - Siemens Simatic RF600 System Manual

6.2.7

Setting RF620A parameters for RF650R/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 RF620A 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 transmit power of up to 70 mW ERP (or 18.85 dBm ERP, 120 mW EIRP,
21 dBm EIRP) an RF620A antenna gain of 5 dBi and taking into account the cable loss
associated with the antenna cable, the radiated power of the antenna cannot be exceeded.
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. 2000 mW radiated power of the readers 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 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
Due to the low antenna gain of 5 dBi and the maximum transmit power of 1000 mW or 2000
mW of the reader, the maximum permitted radiated power cannot be exceeded.
