Foreword
This European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic compatibility and
Radio spectrum Matters (ERM).
Every EN prepared by ETSI is a voluntary standard. The present document contains technical characteristics and test
methods for the equipment to which it relates. This text should be considered as guidance only and does not make the
present document mandatory.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [i.6] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
Annex A provides normative specifications concerning radiated measurements.
Annex B provides normative specifications on tests to be carried out on interrogators that include the optional feature
called "Listen Before Talk".
The present document is part 1 of a multi-part deliverable covering Radio Frequency Identification Equipment
operating in the band 865 MHz to 868 MHz with power levels up to 2 W, as identified below:
Part 1: "Technical requirements and methods of measurement";
Part 2: "Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive".
The present document includes improvements to the previous version of the standard that take advantage of technical
developments within the RFID industry. In particular this includes the ability for multiple interrogators to transmit
simultaneously on the same channel. This provides significant improvements in spectrum efficiency and system
performance. As a consequence "Listen Before Talk" is no longer a requirement.

National transposition dates
Date of adoption of this EN: 7 November 2011
Date of latest announcement of this EN (doa): 29 February 2012
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 31 August 2012
Date of withdrawal of any conflicting National Standard (dow): 31 August 2012

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 e.r.p. of 2 W are specified for this equipment in the frequency range 865 MHz
to 868 MHz.
The present document applies to RFID interrogators and tags operating together as a system. The interrogators transmit
in four specified channels of 200 kHz each using a modulated carrier. 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 EN 301 489-1 [i.1] and 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 Technical requirement specifications
4.1 General requirements
Interrogators shall transmit on any of the high power channels specified in clause 4.2.2.1 at power levels up to the limit
specified in clause 8.3.3.
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 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.
In a preferred method of operation tags, that are activated by an interrogator transmitting in a high power channel,
respond in the adjacent low power channels. This technique is called the dense interrogator mode. It has the benefit of
separating the frequencies of transmission of the interrogators and tags, allowing multiple interrogators to share the
same channel thereby improving system performance. It also minimizes the generation of inter-modulation products,
which may disrupt the behaviour of tags.
The interrogator shall be so designed as to ensure that its length of transmission is no greater than is necessary to
perform the intended operation. Interrogators shall support trigger techniques that indicate the presence or arrival of
objects that may be tagged. Irrespective of the application, an interrogator shall stop transmitting after it has ceased to
read any further tags, as specified in clause 8.6.3.
Interrogators may also operate in a presence sensing mode in which they periodically transmit to determine whether
tags have entered their interrogation zones. When operating in this mode, interrogators shall restrict the length of each
transmission to less than 1 second and the period between successive transmissions shall be no less than 100 ms. Once
an interrogator has determined the presence of tags, it will commence its reading routine.
4.2 Presentation of equipment for testing purposes
Equipment submitted for testing shall fulfil the requirements of the present document on all frequencies over which it is
intended to operate.
Providers shall select frequencies of operation in accordance with the channel plan defined in clause 4.2.2.1 and in
accordance with the power levels defined in clause 8.3.3.
If equipment is designed to operate with different carrier powers, measurement of each transmitter parameter shall be
performed at the highest power level at which the transmitter is intended to operate.
To simplify and harmonize the testing procedures between the different testing laboratories, measurements shall be
performed according to the present document on samples of equipment as defined in clauses 4.2.1 to 4.5. These clauses
are intended to give confidence that the requirements set out in the present document have been met without the
necessity of performing the full measurements at all frequencies.

Foreword This European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Every EN prepared by ETSI is a voluntary standard. The present document contains technical characteristics and test methods for the equipment to which it relates. This text should be considered as guidance only and does not make the present document mandatory. The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC [i.6] (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. Annex A provides normative specifications concerning radiated measurements. Annex B provides normative specifications on tests to be carried out on interrogators that include the optional feature called "Listen Before Talk". The present document is part 1 of a multi-part deliverable covering Radio Frequency Identification Equipment operating in the band 865 MHz to 868 MHz with power levels up to 2 W, as identified below: Part 1: "Technical requirements and methods of measurement"; Part 2: "Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive". The present document includes improvements to the previous version of the standard that take advantage of technical developments within the RFID industry. In particular this includes the ability for multiple interrogators to transmit simultaneously on the same channel. This provides significant improvements in spectrum efficiency and system performance. As a consequence "Listen Before Talk" is no longer a requirement.

ETSI ETSI EN 302 208-1 V1.4.1 (2011-11) 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 e.r.p. of 2 W are specified for this equipment in the frequency range 865 MHz to 868 MHz. The present document applies to RFID interrogators and tags operating together as a system. The interrogators transmit in four specified channels of 200 kHz each using a modulated carrier. 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 EN 301 489-1 [i.1] and 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 References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

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 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. In a preferred method of operation tags, that are activated by an interrogator transmitting in a high power channel, respond in the adjacent low power channels. This technique is called the dense interrogator mode. It has the benefit of separating the frequencies of transmission of the interrogators and tags, allowing multiple interrogators to share the same channel thereby improving system performance. It also minimizes the generation of inter-modulation products, which may disrupt the behaviour of tags. The interrogator shall be so designed as to ensure that its length of transmission is no greater than is necessary to perform the intended operation. Interrogators shall support trigger techniques that indicate the presence or arrival of objects that may be tagged. Irrespective of the application, an interrogator shall stop transmitting after it has ceased to read any further tags, as specified in clause 8.6.3. Interrogators may also operate in a presence sensing mode in which they periodically transmit to determine whether tags have entered their interrogation zones. When operating in this mode, interrogators shall restrict the length of each transmission to less than 1 second and the period between successive transmissions shall be no less than 100 ms. Once an interrogator has determined the presence of tags, it will commence its reading routine. 4.2 Presentation of equipment for testing purposes Equipment submitted for testing shall fulfil the requirements of the present document on all frequencies over which it is intended to operate. Providers shall select frequencies of operation in accordance with the channel plan defined in clause 4.2.2.1 and in accordance with the power levels defined in clause 8.3.3. If equipment is designed to operate with different carrier powers, measurement of each transmitter parameter shall be performed at the highest power level at which the transmitter is intended to operate. To simplify and harmonize the testing procedures between the different testing laboratories, measurements shall be performed according to the present document on samples of equipment as defined in clauses 4.2.1 to 4.5. These clauses are intended to give confidence that the requirements set out in the present document have been met without the necessity of performing the full measurements at all frequencies.
