Foreword
This Interim European Telecommunication Standard (I-ETS) has been prepared by the Radio Equipment
and Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This I-ETS has been adopted having undergone the ETSI standards approvals procedure.
This I-ETS will in future be likely to be superseded or complemented by a corresponding ETS.
This standard is based upon CEPT Recommendation T/R 24-01 [1], and is complementary to
ETS 300 086 [2], which covers radio equipment for use in the land mobile service and intended primarily
for analogue speech.
This is a general standard which may be superseded or complemented by specific standards addressing
specific applications. It applies to equipment designed to operate within the private mobile radio service
and to the associated frequency planning.
This standard is voluntary in application, however, it may be made mandatory by national administrations
as a part of the conditions attached to the issue of licenses for the use or sale of radio apparatus.
Additional standards or specifications may also be required for equipment such as that intended for
connection to the public switched telephone network (PSTN), or data networks.
Constant envelope modulation should be used. The particular type of modulation will be chosen by the
manufacturer, although it is recognized that in some countries national legislation may limit the use of
certain code structures/data formats.
Channel separations, temperature range, maximum transmitter output power/effective radiated power,
class of transmitter intermodulation attenuation and channel access timings may be conditions to the issue
of a licence by the appropriate administration.
This standard does not cover requirements for radiated emissions below 30 MHz. It is anticipated that
methods of measurements and minimum standards for such emissions will be covered by standards
supporting EMC Directive 89/336/EEC.
All transmissions according to this standard should include at specified moments, an information
establishing the identity of the transmitter.
The means of system identification should be approved by the appropriate national regulatory authority.
Annex A: provides additional information concerning radiated measurements.
Annex B: is normative and gives the requirements for equipment to be used for the measurement of
adjacent channel power.
Annex C: is normative and gives a graphic representation of subclause 4.1.2, referring to the
presentation of equipment for testing purpose.
Annex D: is informative and presents the technical characteristics to be fulfilled, when required by
the appropriate national regulatory authority, for the identification of stations type
approved for private mobile radio systems, that do not comply with other system protocols
(e.g. trunking protocols); it is the responsibility of the manufacturer to ensure that the
modulation that he has chosen for the identification, in accordance with the tables of this
annex fulfils the requirements corresponding to the channels where the equipment is
designed to operate, as specified in the main body of this standard. The tables of this
annex are expected to be updated regularly in order to reflect the progress accomplished
in the field of mobile data transmissions. It is envisaged that this annex could be normative
in the future when I-ETS 300 113 will be turned, when mature, into an ETS.

Page 10
I-ETS 300 113: January 1992
Annex E: is informative and provides guidance concerning the technical characteristics of the
modulation, coding and format.
Annex F: is normative, it applies to equipment to be operated in shared channels (for further details,
see Clause F.1); it also contains two methods of measurement used for the assessment
of receiver timing parameters. No other access protocol and occupation rules shall be
made mandatory for cases where this annex is applicable.
Introduction
This standard is intended to specify the minimum performance and the methods of measurement of radio
equipment for use in the land mobile service as specified in the scope.
Clause 5 provides the corresponding limits. These limits have been chosen to ensure an acceptable grade
of service and to minimise harmful interference to other equipment and services. They are based on the
interpretation of the measurement results in subclause 4.3.
This standard will be used by accredited test laboratories for the assessment of the performance of the
equipment. The performance of the equipment submitted for type testing should be representative of the
performance of the corresponding production model. In order to avoid any ambiguity in that assessment,
this standard contains instructions for the presentation of equipment for type testing purposes, Clause 4,
measurement methods, Clauses 8, 9 and 10, and conditions, Clauses 6 and 7.
This standard may also be used by monitoring services in particular for the identification of stations (see
Annex D).
This standard was drafted on the assumption that:
- the type test measurements will be performed only once in one of the
accredited test laboratories and the measurement accepted by the various
authorities in order to grant type approval;
- if equipment available on the market is required to be checked it should be
tested in accordance with the methods specified in this standard.
This standard covers base stations, mobile stations and two categories of handportable stations. One
category is fitted with an antenna socket or connector. The other category has no external antenna socket,
but either:
- it is fitted with a permanent internal 50 Ω Radio Frequency (RF)
connector;
- or, it can be fitted with a temporary internal 50 Ω RF connector, so that
conducted measurements can be performed.
The means to access and/or implement the internal connector should be provided by the manufacturer.
Details of the means actually used during the type testing should be recorded by the accredited test
laboratory in the test report (see subclause 4.2.4).

1 Scope
This Interim European Telecommunication Standard (I-ETS) 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 which may be required by a user, nor does it necessarily represent the
optimum performance achievable. It applies to constant envelope angle modulation systems for use in the
land mobile service, using the available bandwidth, operating on radio frequencies between 30 MHz and
1000 MHz, with channel separations of 12,5 kHz, 20 kHz and 25 kHz intended for data transmissions. It
applies to non-speech and combined analogue speech/non-speech radio equipment for the transmission of
data.
It is also recognised that mobile data systems using high bit rates may have an occupied bandwidth which
is excessive for the existing channel separation. Equipment for such systems operating with modulation bit
rates higher than 2400 bits/s may be the subject of another standard, with different limits, although the
methods of measurement may be the same.
In this standard different requirements are given for the different radio frequency bands, channel
separations, etc., where appropriate.
In this standard, data transmission systems are defined as systems which transmit and/or receive data.
The equipment shall comprise of a transmitter and associated encoder and modulator and/or a receiver
and associated demodulator and decoder.
The types of equipment covered by this standard are as follows:
- Base Station (equipment fitted with an antenna socket, intended for use in a fixed
location);
- Mobile Station (equipment fitted with an antenna socket, normally used in a vehicle or
as a transportable);
- and those Handportable Stations:
a) fitted with an antenna socket;
or,
b) without an external antenna socket (integral antenna equipment), but fitted with a
permanent internal or a temporary internal 50 Ω RF connector which allows
access to the transmitter output and the receiver input.
For the type of equipment defined in b) the following additional measurements shall be made with the
equipment antenna connected (and not through any connector):
- transmitter effective radiated power;
- transmitter radiated spurious emissions;
- receiver maximum usable sensitivity (data, field strength);
- receiver radiated spurious radiations.
Handportable equipment without an external or internal R.F. connector and without the possibility of having
a temporary internal 50 Ω RF connector is not covered by this standard.
In the case of combined full bandwidth analogue speech/full bandwidth non-speech equipment, if the
speech part of the equipment has already been type approved according to ETS 300 086 [2], only some

Page 12
I-ETS 300 113: January 1992
additional measurements have to be performed. They shall ensure that the equipment fulfils the
requirements of the following subclauses:
5.1.4 (Adjacent channel power);
5.1.5 (Spurious emission);
5.1.7 (Transmitter attack time);
5.1.8 (Transmitter release time);
5.1.9 (Transient behaviour of the transmitter);
5.2.1 (Maximum usable sensitivity (data, conducted));
5.2.2 (Maximum usable sensitivity (data, field strength));
5.2.3 (Bit error rate in normal operation);
5.2.4 (Co-channel rejection);
5.2.5 (Adjacent channel selectivity);
5.2.10 (Carrier sense delay); and,
5.2.11 (Receiver opening delay).
The measurement in subclause 8.6 (Spurious emissions) shall be performed when testing an add-on data
unit to an equipment previously type approved to ETS 300 086 [2]. In the case of equipment originally
combined for speech and data, the measurement does not need to be performed when the data-part is
operational while making the test corresponding to ETS 300 086 [2].
In the case where an equipment has already been type approved according to this standard, and is
resubmitted with an add-on device, using another type of modulation, only some additional measurements
have to be performed. They shall ensure that the equipment fulfils the requirements of the following
subclauses:
5.1.4 (Adjacent channel power);
5.1.5 (Spurious emission);
5.2.1 (Maximum usable sensitivity (data, conducted));
5.2.2 (Maximum usable sensitivity (data, field strength));
5.2.3 (Bit error rate in normal operation);
5.2.4 (Co-channel rejection);
5.2.5 (Adjacent channel selectivity);
5.2.11 (Receiver opening delay).
In the case where low bit rate data is transmitted together with speech, the speech part of the equipment
is tested according to ETS 300 086 [2], and it will also be checked that the low bit rate data does not
make the adjacent channel power and spurious emissions fall outside the appropriate limits.
