Foreword
This European Telecommunication Standard (ETS) has been produced by the ETSI Project Broadband
Radio Access Networks (BRAN) of the European Telecommunications Standards Institute (ETSI).
This ETS has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of
information in the field of technical standards and regulations.
This ETS, together with ETS 300 826 [3], is intended to become a Harmonized Standard, the reference of
which will be published in the Official Journal of the European Communities referencing the Council
Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility
("the EMC Directive") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex D.
This ETS consists of 4 parts as follows:
Part 1: "Radio type approval and Radio Frequency (RF) conformance test specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification";
Part 4: "Abstract Test Suite (ATS) specification".

1 Scope
This European Telecommunication Standard (ETS) specifies the radio type approval and Radio
Frequency (RF) conformance testing of the HIgh PErformance Radio Local Area Network (HIPERLAN)
functional specification as specified in ETS 300 652 [1].
HIPERLAN is confined to the lowest two Open Systems Interconnection (OSI) layers, namely the physical
layer and the data link layer. Functions of higher layers are required for operation and interworking of a
complete system and are outside the scope of HIPERLAN.
This ETS applies only to Units Under Test (UUT) operating in the band 5,15 GHz to 5,30 GHz. The use of
the band 17,1 GHz to 17,3 GHz is covered by other HIPERLAN standards.
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the latest
edition of the publication referred to applies.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply, in addition to those given in ETS 300 652 [1].
all conditions: Normal and extreme conditions.
antenna diversity: A plurality of RF input ports to a HIPERLAN receiver, or output ports of a transmitter.
For reception, it is implied that the set of signals from the set of ports can have low cross-correlation. For
transmission, it is implied that transmitted signals from the set of ports can have low cross-correlation at a
general point in space. It is also allowed that a HIPERLAN node can select different antenna properties
such as gain, polarization, coverage pattern, or other feature(s) that can affect the practical coverage. A
typical example is space diversity.

4 General
4.1 Supplier declarations
Where parameters, capabilities, etc., are subject to suppliers declaration and not a specific test, it shall be
the suppliers responsibility to:
- supply equipment conforming to ETS 300-652 [1];
- include a completed copy of the PICS (see ETS 300 836-2 [2]) with the appropriate application form
and a copy of the user manual for the HIPERLAN UUT;
- be prepared to submit upon request supporting design information, including test methods
(additional to this document), circuit designs and software source code, demonstrating the
implementation of the said capabilities.
The supplier shall declare the following specific characteristics of the equipment:
a) the type of UUT, either combined or plug-in (see subclause 4.2.2);
b) where extreme operating conditions apply to the equipment offered for testing that are more
stringent than those specified in subclause 5.4, these shall be declared;

Page 12
ETS 300 836-1: May 1998
c) where the radio equipment is capable of different transmitter power settings, the supplier shall
declare the intended combination(s) of the radio equipment power settings and one or more
antenna assemblies. For each combination, the gain and polarization of the antenna assembly, i.e.
the transfer function between the conducted RF power and EIRPEP, shall be declared;
d) in the case of plug-in devices, the nominal voltages of the combined radio equipment or the nominal
voltages of the host equipment.
4.2 Presentation of equipment for type testing
4.2.1 Choice of model
The supplier shall offer one or more production models or equivalent preliminary models, as appropriate,
for type testing.
Software fitted to production models should be substantially the same as that used during type testing.
Due to the low levels of RF signal and the wideband modulations used in this type of equipment, radiated
RF power measurements are imprecise. Conducted measurements are much more precise. In
combination with the declared antenna assembly gain(s) adequate assurance of the RF characteristics
can be achieved. Therefore, equipment offered for testing should provide a suitable connector for
conducted RF power measurements. If such a connector is not provided, radiated measurements shall be
performed (see annexes A and B).
4.2.2 Presentation
Combined equipment shall be offered complete with all equipment needed for testing.
Plug-in HIPERLAN equipment is intended for use with a variety of host systems. The supplier of plug-in
equipment shall supply a suitable test configuration consisting of either a host system intended for normal
use or a test jig that is representative of the range of host systems in which the UUT may be used. The
test jig shall allow the UUT to be powered and stimulated in a way similar to the way it would be powered
and stimulated when connected to or inserted into host equipment.
4.3 Design
4.3.1 General
The equipment submitted by the supplier, shall be designed, constructed and manufactured in accordance
with good engineering practice, and with the aim of minimizing harmful interference to other equipment
and services.
4.3.2 Controls
There shall be no controls or software accessible to the end user which, if maladjusted, might increase the
radio interfering potential of the equipment. This does not apply to test harnesses and software supplied
solely for the purposes of testing.
4.4 Recording of measurement results
The test results shall be recorded in the appropriate test report form.
The recorded value of the measurement uncertainty for each measurement shall be equal to or lower than
the figures in table 5.
5 Test conditions
5.1 Normal and extreme test conditions
Tests shall be made under the test conditions as specified in the test purposes (see also subclause 4.1
regarding supplier declarations).

Page 13
ETS 300 836-1: May 1998
5.2 Power sources
During type tests, the normal power source of the equipment shall be replaced by a test power source
capable of producing normal and extreme test voltages as specified in subclauses 5.3.2 and 5.4.2. For the
purpose of tests, the voltage of the power source shall be measured as close as possible to the input
terminals of the UUT. However, the measurement uncertainty limits in table 5 shall apply.
5.3 Normal test conditions
5.3.1 Normal temperature and humidity
The normal temperature and humidity conditions for tests shall be any convenient combination of
temperature and humidity within the following ranges:
- temperature: +15°Celcius to +35°Celcius;
- relative humidity: 20 % to 75 %.
The actual values during the tests shall be recorded in the appropriate test report form.
5.3.2 Normal power source
5.3.2.1 Mains voltage
The normal test voltage for equipment to be connected to the mains shall be the nominal mains voltage
and frequency. For the purpose of this ETS, the nominal voltage shall be the declared voltage or any of
the declared voltages for which the equipment was designed.
5.3.2.2 Lead-acid battery power sources used on vehicles
When radio equipment is intended for operation from the usual, alternator fed lead-acid battery power
source used on vehicles, then the normal test voltage shall be 1,1 times the nominal voltage of the battery
(6V, 12V, etc.).
5.3.2.3 Other power sources
For operation from other power sources or types of battery (primary or secondary), the nominal test
voltage shall be as declared by the equipment supplier. This shall be recorded in the appropriate test
report form.
5.4 Extreme test conditions
If the supplier declares test conditions more extreme than those specified in subclause 5.4.1 then the
suppliers declaration shall be substituted.
5.4.1 Extreme temperatures
For tests at extreme temperatures, measurements shall be made in accordance with the procedures
specified in subclause 5.4.3, at the upper and lower temperatures of the range as follows:
- temperature: - 20°Celcius to + 55°Celcius.
Where the suppliers declared operating range does not include the range of - 20°Celcius to + 55°Celcius,
the equipment shall be tested over the following temperature ranges:
a) 08°C to + 35°C for equipment intended for indoor use only, or intended for use in areas where the
temperature is controlled within this range;
b) over the extremes of the operating temperature range(s) of the declared host equipment(s) in case
of plug-in radio devices.
Page 14
ETS 300 836-1: May 1998
The temperature range used in the type testing shall be recorded in the test report form and shall be
stated in the user manual.
5.4.2 Extreme power source voltages
Tests at extreme power source voltages specified below are not required when the UUT is designed for
operation as part of and powered by another system or piece of equipment. Where this is the case, the
limit values of the host system or host equipment shall apply. The appropriate limit values shall be
declared by the supplier and recorded in the test report.
5.4.2.1 Mains voltage
The extreme test voltage for equipment to be connected to an AC mains source shall be the nominal
mains voltage ±10 %.
5.4.2.2 Lead-acid battery power sources used on vehicles
When radio equipment is intended for operation from the usual type of alternator fed lead-acid battery
power source used on vehicles, then extreme test voltage shall be 1,3 and 0,9 times the nominal voltage
of the battery (6 V, 12 V, etc.).
5.4.2.3 Power sources using other types of batteries
The lower extreme test voltages for equipment with power sources using the following types of battery,
shall be:
- for the Leclanche or lithium type battery: 0,85 times the nominal voltage of the battery;
- for the mercury or nickel-cadmium type of battery: 0,9 times the nominal voltage of the battery.
In both cases, the upper extreme test voltage shall be 1,15 times the nominal voltage of the battery.
5.4.2.4 Other power sources
For equipment using other power sources, or capable of being operated from a variety of power sources
(primary or secondary), the extreme test voltages shall be those declared by the supplier; these shall be
recorded in the test report.
5.4.3 Procedure for tests at extreme temperatures
Before measurements are made the equipment shall have reached thermal balance in the test chamber.
The equipment shall be switched off during the temperature stabilizing period. In the case of equipment
containing temperature stabilizing circuits designed to operate continuously, these circuits shall be
switched on for 15 minutes after thermal balance has been reached. After this time the equipment shall
meet the specified requirements. For this type of equipment the supplier shall provide for the power
source circuit feeding these circuits to be independent of the power source of the rest of the equipment.
If thermal balance is not checked by measurements, a temperature stabilizing period of at least one hour,
or such period as may be decided by the testing laboratory, shall be allowed. The sequence of
measurements shall be chosen and the humidity content in the test chamber shall be controlled so that
excessive condensation does not occur.
Before tests at the upper extreme temperature, the equipment shall be placed in the test chamber and left
until thermal balance is attained.
For tests at the lower extreme temperature, the equipment shall be left in the test chamber until thermal
balance is attained, then switched to the standby or receive condition for a period of one minute after
which the equipment shall meet the specified requirements.

6 Transmitter
In this clause on transmitter measurements, the procedures to test equipment which is fitted with a
permanent antenna connector and the procedures to test equipment which is designed to only be used
with an integral antenna are in general combined into one single test description.
For HIPERLANs fitted with an integral antenna and having no means of connecting an external antenna,
tests are specified in terms of received field strength. The power levels in ETS 300 652 [1] assume an
isotropic antenna and can be readily converted to field strength.
EXAMPLE 1: Refer to ETS 300 652 [1], table 43, subclause 9.9.3.1. At the sensitivity limit, an
incident field strength of 119 mV/m is implied for class A receiver equipment,
(and relevant for receiver equipment of classes B and C).
Thus, whatever the antenna gain value declared by the supplier, the limiting sensitivity is always defined in
terms of field strength. The equivalent Field Strength (FS) can be calculated in V/m as follows:
F 377··p4 P
 
FS =
 
Łłc G
Where F is the frequency corresponding to the channel in use, c is the speed of light, 377 A is the
impedance of free space, P is the power specified in ETS 300 652 [1] and G is the gain of the antenna
(= 1,0 (0 dBi) for an isotropic antenna).
For UUTs fitted with a permanent antenna connector, conducted measurements shall be made. For all
tests identified in annex C as intended for type approval, the nominal antenna gain declared by the
supplier in the PICS (ETS 300 836-2 [2])
