Die Annotation des Normtextes ČSN ETSI EN 302208-2-V2.1.1 (875121):

V2.1.1 The present document applies to RFID interrogators and tags operating together as a system. The interrogators transmit either within the lower band in up to four specified channels of 200 kHz or in the upper band in up to four specified channels of 400 kHz. The tags preferably respond with a modulated signal in the adjacent low power channels. Interrogators may be used with either integral or external antennas. The present document applies to RFID interrogators used in conjunction with their RFID transponders (tags). The interrogators preferably operate in the dense interrogator mode in either 200 kHz channels or 400 kHz channels as applicable using a modulated carrier. The tags respond in the adjacent channels with a modulated signal. Interrogators may be used with either integral or external antennas. The types of equipment covered by the present document are as follows: " fixed interrogators; " portable interrogators; " batteryless tags; " battery assisted tags; " battery powered tags. The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive), article 3.2, which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive [i.1] may apply to equipment within the scope of the present document.
