IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does

Foreword
This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM), and is now submitted for the combined Public Enquiry and Vote
phase of the ETSI standards EN Approval Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.10] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.9].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive, and associated
EFTA regulations.
The present document is covering Short Range Devices (SRD) Radio equipment to be used in the 40 GHz to 246 GHz
frequency range.

Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document specifies technical characteristics and methods of measurements for Non-specific Short Range
Devices category equipment types.
Non specific SRDs category is defined by the EU Commission Decision 2013/752/EU [i.2] as:
• "The non-specific short-range device category covers all kinds of radio devices, regardless of the application
or the purpose, which fulfil the technical conditions as specified for a given frequency band. Typical uses
include telemetry, telecommand, alarms, data transmissions in general and other applications".
The present document covers equipment:
• capable of operating in frequency bands listed in table 1;
• intended for fixed, mobile or nomadic use;
• either with a Radio Frequency (RF) output connection and dedicated antenna or with an integral antenna;
• with all types of modulation.
Table 1: Short Range Devices within the 40 GHz to 246 GHz frequency range
Frequency Bands Applications
(Transmit and Receive)
57 GHz to 64 GHz Non-specific SRD
61,0 GHz to 61,5 GHz Non-specific SRD
122 GHz to 123 GHz Non-specific SRD
244 GHz to 246 GHz Non-specific SRD

NOTE 1: The frequency usage conditions for Non-specific SRDs are EU wide harmonised bands according to EC
Decision 2013/752/EU [i.2] as known at the date of publication of the present document. In addition, it
should be noted that other frequency bands may be available for short range devices in a country within
the frequency range 40 GHz to 246 GHz covered by the present document. See the CEPT/ERC
Recommendation 70-03 [i.1] or as implemented through National Radio Interfaces (NRI) and additional
NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.9] is given in annex A.
