Siemens SIMATIC RF600 Series System Manual page 205

Operation in China
By setting a max. radiated power of 2000 mW ERP (or 33 dBm ERP, 3250 mW EIRP,
35 dBm EIRP), an RF640A antenna gain of 4.3 dBi (7.3 dBic) and taking into account the
cable loss associated with the antenna cable (see table (Page 202)), the radiated power of
the reader 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)
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
By selecting the correct country profile/frequency range and setting the radiated power (see
technical specifications of the reader being used) and setting the parameters for antenna
gain and cable loss, the maximum radiated power will not be exceeded.
