The present document specifies technical characteristics and methods of measurements for Radio Frequency Identification (RFID) devices used in the frequency ranges 865 MHz to 868 MHz and 915 MHz to 921 MHz. Power limits up to a maximum of 2 W e.r.p. are specified for this equipment in the frequency band 865 MHz to 868 MHz and up to a maximum of 4 W e.r.p. in the frequency band 915 MHz to 921 MHz. NOTE 1: The term frequency band is used for reference to dedicated bands as described in CEPT/ERC/REC 70-03 [i.9], while frequency range is used in the other cases. The frequency usage conditions for RFID are EU wide harmonised in the band 865 MHz to 868 MHz according to [i.15] and in the band 915 MHz to 921 MHz according to [i.14]. According to [i.14], EU member states are requested to implement 3 channels only in the 915 MHz to 921 MHz band. It should be noted that the frequency band 915 MHz to 921 MHz has only a limited implementation status within the European Union and the CEPT countries. CEPT/ERC/REC 70-03 [i.9] provides in appendix 1 an overview of countries where the band is implemented. The present document applies to RFID interrogators and tags operating together as a system. For each specified band, multiple high power channels are made available for use by interrogators. The tags respond with a modulated signal preferably in the adjacent low power channels. Interrogators may be used with either integral or external antennas.
