1 Scope
The present document covers the minimum characteristics considered necessary in order to make the best use of the
available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it
necessarily represent the optimum performance achievable.
Radio frequency identification products covered within the present document are considered by definition short-range
devices. 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.
The present document applies to RFID interrogators and tags operating together as a system. For each specified band,
four 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.
ElectroMagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-1 [i.1] and ETSI
EN 301 489-3 [i.2].
The types of equipment covered by the present document are as follows:
• fixed interrogators;
• portable interrogators;
• batteryless tags;
• battery assisted tags;
• battery powered tags.

4.1 General requirements
Interrogators shall transmit on any of the high power channels specified in clause 4.2.2.1 for the purpose of
communicating with tags at power levels up to the limits specified in clause 8.3.3.
When operating in the lower band, 865 MHz to 868 MHz, an interrogator may transmit a continuous signal on any of
the high power channels for a period not exceeding the limit defined in clause 8.6.3. At the end of the transmission the
interrogator shall not transmit again on the same channel for the period defined in clause 8.6.3. Alternatively the
interrogator may switch immediately to any one of the other high power channels and send a further continuous
transmission in accordance with the requirements of clause 8.6.3. There is no limit to the number of times that this
process may be repeated.
For the lower band interrogators shall support trigger techniques that indicate the presence or arrival of objects that may
be tagged. Irrespective of the application, an interrogator operating in the lower band shall stop transmitting after it has
ceased to read any further tags, as specified in clause 8.6.3.
For operation in the upper band, 915 MHz to 921 MHz, interrogators s

1 Scope
The present document covers the minimum characteristics considered necessary in order to make the best use of the
available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it
necessarily represent the optimum performance achievable.
Radio frequency identification products covered within the present document are considered by definition short-range
devices. 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.
The present document applies to RFID interrogators and tags operating together as a system. For each specified band,
four 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.
ElectroMagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-1 [i.1] and ETSI
EN 301 489-3 [i.2].
The types of equipment covered by the present document are as follows:
• fixed interrogators;
• portable interrogators;
• batteryless tags;
• battery assisted tags;
• battery powered tags.

4.1 General requirements
Interrogators shall transmit on any of the high power channels specified in clause 4.2.2.1 for the purpose of
communicating with tags at power levels up to the limits specified in clause 8.3.3.
When operating in the lower band, 865 MHz to 868 MHz, an interrogator may transmit a continuous signal on any of
the high power channels for a period not exceeding the limit defined in clause 8.6.3. At the end of the transmission the
interrogator shall not transmit again on the same channel for the period defined in clause 8.6.3. Alternatively the
interrogator may switch immediately to any one of the other high power channels and send a further continuous
transmission in accordance with the requirements of clause 8.6.3. There is no limit to the number of times that this
process may be repeated.
For the lower band interrogators shall support trigger techniques that indicate the presence or arrival of objects that may
be tagged. Irrespective of the application, an inte

ETSI ETSI EN 302 208-1 V2.1.1 (2015-02) 8 1 Scope The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable. Radio frequency identification products covered within the present document are considered by definition short-range devices. 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. The present document applies to RFID interrogators and tags operating together as a system. For each specified band, four 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. ElectroMagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-1 [i.1] and ETSI
EN 301 489-3 [i.2]. The types of equipment covered by the present document are as follows: • fixed interrogators; • portable interrogators; • batteryless tags; • battery assisted tags; • battery powered tags. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
