ANNEX 11: RADIO FREQUENCY IDENTIFICATION APPLICATIONS

Scope of annex
This annex covers frequency bands and regulatory as well as informative parameters recommended for radio frequency identification (RFID) applications including for example automatic article identification, asset tracking, alarm systems, waste management, personal identification, access control, proximity sensors, anti-theft systems, location systems, data transfer to handheld devices and wireless control systems. It should be noted that other types of RFID systems can be operated in accordance with other relevant annexes.

Frequency Band Power / Magnetic Field Spectrum access and mitigation requirements Modulation / maximum occupied bandwidth ECC/ERC Deliverable Notes
a1 865MHz  -  865.6MHz
100 mW e.r.p. No requirement ≤ 200 kHz (note 3)
a 865MHz  -  868MHz
2 W e.r.p. (note1) (note 4) ≤ 200 kHz Operation only when necessary to perform the intended operation, i.e. when RFID tags are expected to be present
a2 865.6MHz  -  867.6MHz
2 W e.r.p. No requirement ≤ 200 kHz (note 3)
a3 867.6MHz  -  868MHz
500 mW e.r.p. No requirement ≤ 200 kHz (note 3)
b 915MHz  -  921MHz
4 W e.r.p. (note 2) For ER-GSM protection (918-921 MHz, where applicable), DAA is required ≤ 400 kHz The frequency band is also identified in Annexes 1 and 10. Operation only when necessary to perform the intended operation, i.e. when RFID tags are expected to be present
c2 2446MHz  -  2454MHz
> 500 mW to 4 W e.i.r.p ≤ 15% duty cycle FHSS techniques should be used Not specified Power levels above 500 mW are restricted to be used inside the boundaries of a building and the duty cycle of all transmissions shall in this case be ≤ 15 % in any 200 ms period (30 ms on /170 ms off)
c1 2446MHz  -  2454MHz
≤ 500 mW e.i.r.p. No requirement Not specified

Note 1 Interrogator transmissions in band a at 2 W e.r.p. are only permitted within the four channels centred at 865.7 MHz, 866.3 MHz, 866.9 MHz and 867.5 MHz; each with a maximum bandwidth of 200 kHz.
Note 2 Interrogator transmissions in band b at 4 W e.r.p., are only permitted within the four channels centred at 916.3 MHz, 917.5 MHz, 918.7 MHz and 919.9 MHz; each with a maximum bandwidth of 400 kHz.
Note 3 RFID interrogator devices placed on the market before the repeal date of EC Decision 2006/804/EC are ‘grandfathered’, i.e. they are continuously permitted to be used in line with the provisions set out in EC Decision 2006/804/EC (see sub-bands a1), a2), and a3)) before the repeal date.
Note 4 The maximum period of continuous interrogator transmission on a channel shall not exceed 4s and the period between consecutive transmissions of an interrogator on the same channel shall be at least 100ms in order to ensure most efficient use of available channels for the general benefit of all users.

Additional Information

Harmonised Standards
EN 300 440 Sub-bands c1) and c2) EN 302 208 Sub-bands a), a1), a2), a3) and b)

Technical parameters also referred to in the harmonised standard
Sub-band a): In addition, antenna beamwidth limits shall be observed as described in the standard EN 302 208. Sub-band c2): In addition, antenna beamwidth limits shall be observed as described in the standard EN 300 440. In addition, for an RFID device which can exceed 500 mW, the device should be fitted with an automatic power control to reduce the radiated power below 500 mW; this automatic power control shall guarantee the reduction of the power to a maximum of 500 mW in cases where the device is moved and used outside the boundary of the user's building or premises as described above.

Frequency issues
Sub-band c2): To assist enforcement authorities any emissions from an RFID device when measured outside of the building at a distance of 10 metres shall not exceed the field strength from a 500 mW RFID device mounted outside the building when measured at the same distance. Where a building consists of a number of premises, such as shops within a shopping arcade or Mall then the measurements shall be referenced to the boundary of the user's premises within the building. Sub-bands a1), a2) and a3): Channel centre frequencies are 864.9 MHz + (0.2 MHz * channel number). The available channel numbers for each sub-band are: a1: channel numbers 1 to 3 a2: channel numbers 4 to 13 a3: channel numbers 14 to 15. Note: The same equipment is allowed to operate in several sub-bands. Frequency hopping or other spread spectrum techniques shall not be used. Sub-band b): Use of all or part of sub-band b) may be denied in some European countries that use all or part of these sub-bands for defence/governmental systems. In other countries that use sub-band 918-921 MHz for GSM for railways, extended band (ER-GSM), access to the part 918-921 MHz by UHF RFID applications requires implementation of additional mitigation measures such as Detect-And-Avoid (DAA) as set out in ECC Report 200. See Appendix 3 for national implementation concerning ER-GSM and defence/governmental services.
