The notice required under the pilot technology
No 〔2007〕 Ministry 205
Provinces, autonomous regions and municipalities Radio Management Office (Bureau), the national radio monitoring
心： Heart:
In order to meet our social and economic development of the 800/900MHz band RFID technology to be
Demand, according to China Radio Frequency Allocation and industrial development, and with the international standards title
Next, develop 800/900MHz band RFID technology trial requirements. Are hereby promulgated, and that
The date of implementation.
Two years on April 20 OO
800/900MHz Band Radio Frequency Identification (RFID)
echnology (Trial)
一、 800/900MHz band RFID technology, the specific use of frequency 840-845MHz and
920-925MHz 。
二、 the frequency band of radio transmitting equipment, radio frequency RFID technology indicators:
1, the carrier frequency tolerance: 20 × 10-6;
2, channel bandwidth and channel bandwidth (99% of energy): 250kHz;
3, channel center frequency:
fc (MHz) = 840.125 + N × 0.25 and
fc (MHz) = 920.125 + M × 0.25 (N, M is an integer with value 0-19);
4, adjacent channel power leakage ratio: 40dB (first adjacent channel), 60dB (second adjacent channel);
5, the transmit power:
Frequency Range (MHz) Transmit power (erp)
840.50-844.5 840.50-844.5
920.50-924.5 2W 920.50-924.5 2W

8, power ports and telecommunication ports conducted disturbance emission should meet the national standard
In GB9254-1998 Class B limits of the equipment requirements;
9, the limit stated in the manufacturers operating voltage, under extreme temperature conditions, equipment
Transmit power and frequency tolerance shall meet the corresponding technical indicators.
三、the band of radio transmitting equipment, RFID technology by micro-power (short distance)
Radio equipment management. Equipment into use, should be no Ministry of Information Industry issued
Radio Transmission Equipment Type Approval Certificate.
In view of 800/900MHz band RFID applications is a new radio technology,
With a relatively wide range, in order to prevent possible radio interference, radio control at all levels
Management agencies to strengthen the band RFID device management, timely detection of treatment-free
Radio interference and ensure the smooth band RFID technology to carry out.
