RFID devices will use 920-925MHz instead of 800-845MHz in China SRRC may assign 920-925MHz for RFID devices used in China which will replace 800-845MHz assigned in 2007.
This new regulation may be published in 2023. The previous approved RFID devices can still be used.
The specs of 920-925MHz RFID devices:
Frequency range:920-925MHz。
Frequency tolerance ≤20×10 -6
Bandwidth: ≤250kHz
Channel center frequency: fc（MHz）=920.125+M×0.25（M =0-19） Effective radiation power limit:
| Frequency | e.r.p |
|---|---|
| 920-920.5 MHz | 100mW |
| 920.5-924.5MHz | 2W |
| 924.5-925 MHz | 100mW |
