6.8 SIMATIC RF680A
Limitations in the USA and Canada
Note
Limitation of the radiated power (FCC)
RF600 systems that are put into operation in the USA and Canada must not exceed the
following radiated power with an RF680A antenna:
• 4000 mW EIRP (or 36 dBm EIRP)
Make the following settings to ensure that the maximum permitted radiated power of the
antenna is not exceeded:
● Conducted power P (dBm) of the RF600 reader: < 30 dBm
● Antenna gain G
● Cable loss a
P (dBm) ≤ 30 dBm - (G
Limitations in China
Note
Limitation of the radiated power (CMIIT)
RF600 systems that are put into operation in China must not exceed the following radiated
power with an RF680A antenna:
• 2000 mW ERP (or 33 dBm ERP)
Converted into EIRP: 3250 mW EIRP (or 35 dBm EIRP)
Make the following settings to ensure that the maximum permitted radiated power of the
antenna is not exceeded:
● Antenna gain: 3 dBi (6 dBic)
● Radiated power: ≤ 2000 mW ERP (or 33 dBm ERP)
Converted into EIRP: ≤ 3250 mW EIRP (or 35 dBm EIRP)
● Use of cable loss associated with the antenna cable.
Limitations in Japan
Note
Limitation of the radiated power (ARIB)
RF600 systems that are put into operation in Japan must not exceed the following radiated
power with an RF680A antenna:
• 500 mW EIRP (or 27 dBm EIRP) for operation with RF650R (ARIB STD-T107)
• 4000 mW EIRP (or 36 dBm EIRP) for operation with RF680R/RF685R (ARIB STD-T106)
