SIST EN 302 326-2 V1.1.1:2006

• Abstract:

  The present document is intended to cover the provisions of the R&TTE Directive [2] regarding article 3.2, which states that "[...] radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".; The present document is applicable to the essential requirements of equipment (including equipment with integral antennas) used in Multipoint (MP) Digital Fixed Radio Systems (DFRS). The present document, together with EN 302 326-3 [12] are intended to replace and supersede, after a suitable transition period, the harmonized EN 301 753 (see bibliography) for all multipoint equipment and antennas. The present document and EN 302 326-3 [12] introduce rationalization among systems conforming to previous EN 301 753 (see bibliography) referencing a number of ENs which, being developed at different times, might have specified slightly different requirements. However, care has been taken so that such variations will not affect any frequency planning assumption for already deployed networks. Therefore, unless specifically mentioned, these new requirements, whenever different from those single ENs, are considered completely "equivalent". Therefore mixed use of equipment conforming to the present document and to those previous one will not change, in practice, any frequency planning rule in any network.; Therefore, from a strictly technical point of view, in most cases it is expected that equipment already conforming to the previous versions of Harmonized EN 301 753 (see bibliography), would not need re-assessment of essential requirements according to the present document. The legal implications of the declaration of conformity and equipment labelling are, however, outside the scope of this whole multi-part deliverable. Cases, where additional conformance assessment is anyhow required, will be specifically mentioned in the present document and also EN 302 326-3 [12].; In addition to the present document, other ENs specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive [2] and which will apply to equipment within the scope of the present document.; NOTE: A list of such ENs is included on the web site http://www.newapproach.org.; In order to (technically) cover different market and network requirements, with an appropriate balance of performance to cost and effective and appropriate use of the radio spectrum, the present document, together with EN 302 326-3 [12], offers a number of system types and antennas alternatives, for selection by administrations, operators and manufacturers dependent on the desired use of the radio spectrum and network/market requirements; those options include:; • channel separation alternatives (as provided by the relevant CEPT Recommendation);; • spectral efficiency class alternatives (different modulation formats provided in radio equipment standards);; • antenna sectorization alternatives and directivity classes for CS;; • antenna directivity class alternatives for TS and/or RS;; • antenna basic polarization (linear or circular).; The applicability of this whole multi-part deliverable to MP equipment is governed by the definition of a number of system profiles that define the set of consistent requirements as described in EN 302 326-1 [11] to which equipment shall conform.; The present document is considered applicable to fixed radio systems products with integral antennas, for which all the technical requirements included in the present document and in EN 302 326-3 [12] apply, and to separate equipment products, to which only the relevant technical requirements apply, and which might therefore be subject to separate declarations of conformity with respect to the essential requirements of the R&TTE Directive [2].

SIST EN 302 326-2 V1.1.1:2006 is the Slovenian adoption of ETSI EN 302 326-2 V1.1.1, published by SIST. It covers the article 3.2 radio-spectrum requirements for Digital Multipoint Radio Equipment in Multipoint Digital Fixed Radio Systems, including equipment with integral antennas. In practice, it tells manufacturers, suppliers and test bodies how to classify the equipment, which transmitter and receiver characteristics to verify, and how to test conformance.

What does SIST EN 302 326-2 V1.1.1:2006 specify?

SIST EN 302 326-2 V1.1.1:2006 specifies the harmonized European requirements for effective spectrum use and harmful-interference avoidance for multipoint fixed radio equipment under the R&TTE Directive. It applies to equipment used in Multipoint (MP) Digital Fixed Radio Systems (DFRS), and it is written as part 2 of a multi-part deliverable that works with EN 302 326-1 and EN 302 326-3.

The standard applies to equipment with or without integral antennas, and to separate equipment products where only the relevant technical requirements apply. It covers systems using any access method, Frequency Division Duplex (FDD) or Time Division Duplex (TDD), and the frequency ranges 30 MHz to 11 GHz, 24.25 GHz to 29.50 GHz, and 31.00 GHz to 33.40 GHz.

The document is organized into six main clauses and seven annexes.

Annex	What it covers
A	Test report provisions for flexible systems applications, including wide radio-frequency band coverage and multirate/multiformat equipment
B	System capacity and minimum capacity rules
C	The EN Requirements Table (EN-RT)
D	Spectrum mask requirements when ATPC and/or RTPC are implemented
E	Summary table of EqC and other parameters for conformance declaration
F	The EN title in the official languages
G	Bibliography

What are the key requirements of SIST EN 302 326-2 V1.1.1:2006?

Clause 1.2 and Clause 1.3 require the supplier to identify the applicable Equipment Classification (EqC) in the technical construction file. The EqC fields - EqC-FR, EqC-PET, EqC-EMO, EqC-SET and EqC-ChS - define the consistent set of requirements that apply to the equipment. For asymmetric systems, the document expects separate EqC declarations for the two directions, so the test plan and declaration match the real operating arrangement.

Clause 5.2 and Clause 6.2 require the equipment to comply within the declared environmental profile, including climatic conditions and power-supply conditions. If the assembly uses a radome, the radome stays in place for assessment. In practice, this means the test conditions must reflect where and how the equipment will really be installed.

Clause 5.3 covers the transmitter requirements: output power, output power tolerance, output frequency stability, adjacent channel power, spurious emissions, power control, Remote Frequency Control (RFC) and dynamic change of modulation order. The standard also requires attenuating means for equipment at or above 1 GHz, and finer adjustment steps at or above 24.25 GHz. For a buyer or test lab, these are the main spectrum-sharing checks because they control occupied bandwidth, drift and unwanted emissions.

Clause 5.3.6 and Annex D explain how Automatic Transmit Power Control (ATPC) and Remote Transmitter Power Control (RTPC) affect compliance. ATPC may raise power in deep fading, but the spectrum mask has to be met over the range from maximum nominal power to maximum available power. Annex D also separates RTPC type 1, used for inter-operator interference balancing, from RTPC type 2, used for intra-system balancing. In practice, the manufacturer has to declare how any software or hardware power-control range is split and tested.

Clause 5.4 covers receiver performance: receiver spurious emissions, minimum Receive Signal Level (RSL), co-channel interference, adjacent channel interference and Continuous Wave (CW) interference. Tables 7, 9, 10, 11 and 12 link the required Bit Error Rate (BER) performance to RSL or interfering-signal levels for different EqC combinations. This is the part that shows whether the receiver can still work in the presence of wanted-channel, adjacent-channel or narrowband interference.

Clause 5.5 and Clause 6.5 add special requirements for equipment with integral antennas, including the Radiation Pattern Envelope (RPE) and antenna gain. The conformance tests reference EN 301 126-3-2. In practice, the radio and antenna are treated as one assembly, so the antenna pattern directly affects the radio’s declared conformity.

Annex B sets minimum system capacity rules. For some equipment types, the standard requires minimum throughput or bit-rate-per-Hz performance in addition to the spectral limits. That matters because a design can meet the radio-emission limits but still fail the standard if it does not carry enough traffic for the declared profile.

Annex A explains how flexible systems are assessed. For wideband and multirate/multiformat equipment, it defines which operating points need testing and how to choose the declared worst-case bit rate, modulation format and error-correction code. Clause 6 then links each requirement to a corresponding conformance test method, so the test report follows the same structure as the technical requirements.

What terms does SIST EN 302 326-2 V1.1.1:2006 define?

• Equipment Classification (EqC) - the multi-field code that identifies the equipment profile and selects the applicable alternative requirements.
• Channel Separation (ChS) - the spacing between neighboring RF channel centre frequencies, used in interference and mask requirements.
• Automatic Transmit Power Control (ATPC) - a function that changes transmit power with propagation conditions so higher power is used mainly during deep fading.
• Remote Transmitter Power Control (RTPC) - a facility for remotely controlling transmitter output power, with type 1 and type 2 used for different balancing purposes.
• Receive Signal Level (RSL) - the signal level at the receiver input, used to judge sensitivity and BER performance.
• Full Capacity Load (FCL) - the maximum load of a Central Station used in transmitter spectrum and capacity assessment.
• Radiation Pattern Envelope (RPE) - the allowed off-axis radiation shape of an antenna, used to control interference from integral antennas.
• Gross Bit Rate (GBR) - the transmission bit rate over the air, which links modulation choice to system capacity.

Who uses SIST EN 302 326-2 V1.1.1:2006?

Manufacturers and suppliers use SIST EN 302 326-2 V1.1.1:2006 to choose the EqC profile, prepare the technical construction file, and declare the equipment’s operating range. Test houses and conformity-assessment bodies use it to select transmitter, receiver and antenna tests and to compile the EN-RT.

Network operators, planners and administrations use it when choosing channel separation, antenna options, modulation classes and spectrum arrangements for multipoint fixed radio networks. It is especially relevant in fixed wireless access, point-to-multipoint and multipoint-to-multipoint deployments, where frequency planning and interference control depend on the declared profile.

What changed in SIST EN 302 326-2 V1.1.1:2006 from the previous edition?

SIST EN 302 326-2 V1.1.1:2006, together with EN 302 326-3, is intended to replace and supersede EN 301 753 for multipoint equipment and antennas.

• It rationalizes requirements that were previously spread across several ENs.
• It treats the new requirements as equivalent for frequency planning when the differences are only technical harmonization changes.
• It states that mixed use of equipment conforming to the old and new documents does not change network frequency planning rules in practice.
• It introduces common CW interference requirements derived from EN 301 390.
• It notes that equipment already assessed against the earlier EN 301 753 often does not need a new reassessment for essential requirements.

Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Transmission and Multiplexing (TM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive") [2].
Technical specifications relevant to Directive 1999/5/EC [2] are given in annex C.
This multi-part deliverable covers characteristics and requirements for fixed multipoint radio equipment and antennas
using a variety of access and duplex methods and operating at a variety of bit rates in frequency bands as specified in
the present document.
The present document is part 2 of a multi-part deliverable covering the Fixed Radio Systems; Multipoint Equipment and
Antennas, as identified below:
Part 1: "Overview and Requirements for Digital Multipoint Radio Systems";
Part 2: "Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive for
Digital Multipoint Radio Equipment";
Part 3: "Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive for
Multipoint Radio Antennas".
The present document and EN 302 326-3 [12] are Harmonized ENs and essential requirements are those requirements
which are essential under article 3.2 of the R&TTE Directive [2].
In the above, "equipment" includes equipment with integral antennas, and "antennas" include requirements for antennas
whether they are integral or non-integral.
The present document with EN 302 326-3 [12] will replace and supersede the harmonized EN 301 753
(see bibliography) for all MP equipment and antennas.
The date of cessation of presumption of conformity to R&TTE Directive [2] with reference to EN 301 753 (see
bibliography, latest version published) is proposed to be two years after the date of publication in the OJ EC of the
present document.

The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows EN 301 489 (see bibliography), the multi-part product EMC standard for radio used
under the EMC Directive 89/336/EEC (see bibliography).
NOTE: For Fixed Radio Systems, EN 301 489-1 and EN 301 489-4 (see bibliography) are relevant.
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive 73/23/EEC
(see bibliography) and new standards covering human exposure to electromagnetic fields. New standards covering
acoustic safety may also be required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [2] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [2] may be covered in a set of standards.
The modularity principle has been taken because:
• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;
• it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions
without requiring alteration of standards that are already published;
• it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.

1 Scope
1.1 General
The present document is intended to cover the provisions of the R&TTE Directive [2] regarding article 3.2, which states
that "[.] radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio
communications and orbital resources so as to avoid harmful interference".
The present document is applicable to the essential requirements of equipment (including equipment with integral
antennas) used in Multipoint (MP) Digital Fixed Radio Systems (DFRS).
The present document, together with EN 302 326-3 [12] are intended to replace and supersede, after a suitable transition
period, the harmonized EN 301 753 (see bibliography) for all multipoint equipment and antennas.
The present document and EN 302 326-3 [12] introduce rationalization among systems conforming to previous
EN 301 753 (see bibliography) referencing a number of ENs which, being developed at different times, might have
specified slightly different requirements. However, care has been taken so that such variations will not affect any
frequency planning assumption for already deployed networks. Therefore, unless specifically mentioned, these new
requirements, whenever different from those single ENs, are considered completely "equivalent". Therefore mixed use
of equipment conforming to the present document and to those previous one will not change, in practice, any frequency
planning rule in any network.
Therefore, from a strictly technical point of view, in most cases it is expected that equipment already conforming to the
previous versions of Harmonized EN 301 753 (see bibliography), would not need re-assessment of essential
requirements according to the present document. The legal implications of the declaration of conformity and equipment
labelling are, however, outside the scope of this whole multi-part deliverable. Cases, where additional conformance
assessment is anyhow required, will be specifically mentioned in the present document and also EN 302 326-3 [12].
In addition to the present document, other ENs specify technical requirements in respect of essential requirements under
other parts of article 3 of the R&TTE Directive [2] and which will apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.
In order to (technically) cover different market and network requirements, with an appropriate balance of performance
to cost and effective and appropriate use of the radio spectrum, the present document, together with EN 302 326-3 [12],
offers a number of system types and antennas alternatives, for selection by administrations, operators and manufacturers
dependent on the desired use of the radio spectrum and network/market requirements; those options include:
• channel separation alternatives (as provided by the relevant CEPT Recommendation);
• spectral efficiency class alternatives (different modulation formats provided in radio equipment standards);
• antenna sectorization alternatives and directivity classes for CS;
• antenna directivity class alternatives for TS and/or RS;
• antenna basic polarization (linear or circular).
The applicability of this whole multi-part deliverable to MP equipment is governed by the definition of a number of
system profiles that define the set of consistent requirements as described in EN 302 326-1 [11] to which equipment
shall conform.
The present document is considered applicable to fixed radio systems products with integral antennas, for which all the
technical requirements included in the present document and in EN 302 326-3 [12] apply, and to separate equipment
products, to which only the relevant technical requirements apply, and which might therefore be subject to separate
declarations of conformity with respect to the essential requirements of the R&TTE Directive [2].

1.2 Classification of equipment
The present document is applicable, in principle to multipoint radio system equipment using any access method,
operating in some combinations of frequency bands, equipment variations on the above access methods (referred to as
secondary equipment type), equivalent modulation orders and channel separation.
The applicability of this whole multi-part deliverable to MP equipment is governed by the definition of a number of
system profiles that define the set of consistent requirements (see clause 1.3) to which equipment shall conform. The
supplier shall uniquely identify in the technical construction file which Equipment Classification(s) (EqC) (among those
limited sets defined in clause 1.3) apply to his equipment and assess it consequently.
Those sets of parameters, relevant to article 3.2 of the R&TTE Directive [2], have been derived from a set of previous
ENs that historically included only parameters derived from a finite number of combinations of basic system
characteristics.
However, from the article 3.2 of R&TTE Directive [2] point of view, it is not required that the systems to be assessed
physically conform to a specific system description. It is, however, necessary that the equipment should conform to a
consistent set of parameters as designated in the present document. The set of parameters for conformance shall be
indicated by the supplier, according to the classification method described in annex A to EN 302 326-1 [11].
The basic system characteristics are described in the Introduction of EN 302 326-1 [11].
1.3 Profiles
1.3.1 General
This whole multi-part deliverable allows many distinct types of equipment, several different antenna types and several
ways in which they might be interconnected to form a network. However, within this whole multi-part deliverable these
are restricted to certain combination of attributes and these combinations of attributes are called "profiles". The
following clauses address:
• Equipment profiles.
• Antenna profiles.
• System profiles.
1.3.2 Equipment profiles
The applicability of the present document is limited to alternative consistent sets of recommendations and requirements,
each for identified equipment profiles, which are defined in terms of their Equipment Classification (EqC) which
classify equipments in terms of key characteristics. The profiles (or indeed any specific equipment) within the scope of
this whole multi-part deliverable may be classified as discussed in normative annex A of EN 302 326-1 [11] in terms of
the various fields of EqC, which are:
• Frequency Range (EqC-FR);
• Primary Equipment Type (EqC-PET);
• Secondary Equipment Type (EqC-SET), (where needed to distinguish variants of EqC-PET);
• Equivalent Modulation Order (EqC-EMO);
• Channel separation (EqC-ChS) - or range of separations;
• Station type (EqC-STN).

12 ETSI EN 302 326-2 V1.1.1 (2005-12)
Table 1 shows the complete list of equipment profiles within the scope of this multi-part deliverable in terms of the
allowed values (or ranges of values) of the various fields of EqC. The manufacturer shall indicate, in the Technical
Construction File or elsewhere, the profile that the specific equipment shall comply with, by defining the values of
those fields of EqC shown in table 1 that are applicable to the equipment. The equipment shall then comply with all
requirements in EN 302 326-1 [11] and the present document relevant to that EqC.
In the case of asymmetric MP implementations (see clause 1.6 of EN 302 326-1 [11]), the supplier shall identify
separately the profiles of the equipment in the two alternate directions in terms of the various EqC fields, and the
present document shall apply independently to each direction.

NOTE 1: A description of the fields of EqC appears in annex A of EN 302 326-1 [11], and the relationship between
EqC fields and the previous equipment types described in the superseded ENs appears in annex B of
EN 302 326-1 [11].
NOTE 2: In the earlier standards a number of system types were defined (e.g. A, B, C, etc.). Annex B of
EN 302 326-1 [11] indicates the relationship between the earlier system types and the present EqC.
NOTE 3: Although EqC-PET historically has a relationship with a specific multiple access method, any access
method, or combination of access methods, may be used provided that the entire set of requirements
relevant to article 3.2 of the R&TTE Directive [2] in the present document and, if desired, also other
complimentary requirements in EN 302 326-1 [11] are met for the stated EqC-PET value.
NOTE 4: In the EqC-EMO column, the reference made to the modulation order is only indicative, and any equivalent
modulation scheme is allowed provided that the whole set of requirements relevant to article 3.2 of the
R&TTE Directive [2] in the present document and, if desired, also other complimentary requirements in
EN 302 326-1 [11] are met for the manufacturer's stated EqC-EMO value. For mixed-mode systems
EqC-EMO=1 might also be provided, among other more efficient EMO, within the same channel separations.

NOTE 5: For certain primary equipment types (EqC-PET) it has historically been necessary to sub-divide the
equipments according to further characteristics which have different consistent sets of requirements.
Although no longer tied to specific characteristics, this subdivision is reflected in Secondary Equipment Type
(EqC-SET) classifications which are represented by various two-letter codes.
(See annex A of EN 302 326-1 [11]).
NOTE 6: The EqC-ChS column indicates range of ChS values for which the present document is applicable. Several
parameters in the present document are given for discrete values of ChS only. For intermediate ChS values,
methods are given for deriving the required characteristics with the default being by interpolation between
the two nearest adjacent ChS values.
NOTE 7: The EqC-FR column represents the basic frequency range for which the present document is applicable. For
assessment purpose the specific frequency band of the equipment/antenna operation should be defined
(e.g. EqC-FR = 3,5 or EqC - FR = 3,4 - 3,6) according the assessment rules for wide band equipment and
antennas defined in annex A of the present document.
NOTE 8: Systems of EqC-PET = H, implementing an actual FH-CDMA access method with hopping period exceeding
400 ms, are not considered within the scope of the present document.

For defining the coherent set of essential test suites for conformity assessment, a number of declared EqC codes and
other parameters are needed as declaration from the supplier. Standing the considerable number of possibilities under
the scope of the present document summarized in table 1 and, for systems with integral antennas in table 3, it is
recommended to consider the production of a summary table, such as table E.1 proposed in informative annex E, to be
attached as header of the technical construction file and/or test documentation for aid the correct identification of the
equipment/system profile by any interested third party.
1.3.3 Antenna profiles
According to their characteristics, multipoint systems use different types of antennas as indicated in clause 1.3.4. The
following table outlines the multipoint antenna types described in EN 302 326-3 [12].
Table 2: Antenna Types
Frequency Range Types Polarization Notes

Sectored single beam may have a symmetric or asymmetric
Omni directional radiation pattern in the elevation plane.
3 GHz to 11 GHz Directional Linear The sectored single and omni directional
Sectored single beam antennas may have a symmetric or
Sectored multibeam (up to asymmetric radiation pattern in the elevation
5,9 GHz only) plane. The sectored multi beam antennas
Omni directional have a symmetric radiation pattern only.
1 GHz to 11 GHz Directional Circular The sectored and omni directional antennas
Sectored single beam may have a symmetric or asymmetric
Omni directional radiation pattern in the elevation plane.
24,25 GHz to 30 GHz Directional Linear
Sectored single beam
30 GHz to 40,5 GHz Directional Linear The omni directional antennas may have a
Sectored single beam symmetric or asymmetric radiation pattern in
Omni directional the elevation plane.

The present document is applicable to multipoint radio system antennas of both linear (single or dual) polarization and
circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually
perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular
polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.
The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or
circular polarized antennas) impact the interference considerations in network planning. A number of antenna options
are defined in EN 302 326-3 [12] to allow a trade-off between highly demanding RPE directivity and the
cost/size/weight of the antennas. The antenna choice should take into account the constraints of present and future
networks requirements and constraints.
Annex B of EN 302 326-3 [12] discusses Antenna Profiles for multipoint systems.
