Fixed Radio Systems - Point-to-point and Multipoint Systems - Unwanted emissions in the spurious domain and receiver immunity limits at equipment/antenna port of Digital Fixed Radio Systems
The term Spurious emissions is used for simplicity elsewhere in the present document but with the more broader meaning of "unwanted emissions in the spurious domain" introduced by Recommendation ITU-R SM.329 [1] for clarifying the Radio Regulation definitions and the application of recommended limits for all unwanted emissions; it also recommends that spurious emissions limits apply to all unwanted emissions falling in the spurious domain. Therefore the present document deals with limits for unwanted emissions in the spurious domain at antenna port of Digital Fixed Radio Systems (DFRS) as defined by Recommendation ITU-R SM.329 [1] and CEPT/ERC Recommendation 74-01 [4] and ECC Recommendation (02)05 [5]. Moreover it covers immunity characteristics at receiver's antenna port. Scope of the present document is to define specific limits at antenna port for spurious emissions domain and receiver immunity for suitable inter-working of Digital Fixed Radio Systems (i.e. Point-to-point and Multipoint systems) in the same or in different frequency band whenever allocated to Fixed Service in the range 9 kHz to 300 GHz. However systems with fundamental emission below 30 MHz are not considered relevant for Digital Fixed Radio Systems and are outside the scope of the present document. Spurious emissions domain levels and immunity performance at antenna port are also relevant to essential requirements under article 3.2 of Directive 1999/5/EC [i.12] on Radio equipment and Telecommunication Terminals equipment (R&TTE). The present document complements CEPT/ERC Recommendation 74-01 [4] which gives limits for Unwanted emissions in the Spurious domain with particular regards to "inter Services" operations, while WG TM4 assumed that in some case more protection is required for compatibility among fixed radio systems deployed in the same geographical area. Additional considerations and background for producing the present document are:
- Recommendation ITU-R SM.329 [1] considers emissions from any system, including digital modulation and allows options for the definition of the frequency boundary between out-of-band domain and spurious emissions domain. It recommends different category of level limits applicable to the Fixed Service;
- Recommendation ITU-R SM.1539 [2] describes the application of the boundary concept between
out-of-band and spurious emission domains;
- Recommendation ITU-R F.1191 [3] define the application of Radio Regulations [i.13] and SM set of
Recommendation ITU-Rs concepts of out-of-band, unwanted and spurious emissions to DFRS, clarify the applicability for the boundary between out-of-band and Spurious emissions domains but maintain the same pos sible limit options provided by ITU-R Recommendation SM.329-10 [1];
- CEPT/ERC Recommendation 74-01 [4], endorses only the more stringent Category B limits of Recommendation ITU-R SM.329-10 [1];
- after the coming into force of RTTE Directive [i.12] the emissions and immunity at antenna port fall under its article 3.2 requirements for "effective use of spectrum" and "avoidance of harmful interference" and they are no longer an EMC requirement;
- it is convenient to maintain a single EN covering these parameters instead of replicating them on each single product standard, avoiding possible deviation from what required by other CEPT and ITU-R normative;
- limits for unwanted emissions in the spurious domain are supposed to be fixed in view of inter-working compatibility among various Fixed Radio Systems in same or different band exploited in the same area;
- the measurement of the required limits should also be feasible in a suitable and cost effective conformance test (annex B gives also information in this field);
- it is necessary that DFRS receivers provide a minimum level of immunity at antenna port towards possible interference at any frequency band of practical interest;
Fiksni radijski sistemi - Sistemi točka-točka in večtočkovni sistemi - Neželena oddajanja in omejitve odpornosti sprejemnika pri vhodu v opremo oziroma pri antenskem vhodu digitalnih fiksnih radijskih sistemov
Izraz »stranska oddajanja« se za poenostavitev uporablja drugje v tem dokumentu, pri čemer ima širši pomen »neželena oddajanja v stranski domeni«, ki ga Priporočilo ITU-R SM.329 [1] uporablja za razjasnitev definicij Pravilnika o radiokomunikacijah in uporabo priporočenih mejnih vrednosti za vsa neželena oddajanja; priporoča tudi, da se mejne vrednosti stranskih oddajanj uporabljajo za vsa neželena oddajanja, ki spadajo v stransko domeno. Ta dokument obravnava mejne vrednosti neželenih oddajanj v stranski domeni pri antenskem vhodu digitalnih fiksnih radijskih sistemov (DFRS), kot je opredeljeno v Priporočilu ITU-R SM.329 [1], Priporočilu CEPT/ERC 74-01 [4] in Priporočilu ECC (02)05 [5]. Poleg tega zajema značilnosti odpornosti pri antenskem vhodu sprejemnika. Področje uporabe tega dokumenta je opredelitev posebnih mejnih vrednosti pri antenskem vhodu za domeno stranskih oddajanj in odpornosti sprejemnika za ustrezno medsebojno delovanje digitalnih fiksnih radijskih sistemov (tj. sistemi točka-točka in večtočkovni sistemi) v enakem ali drugačnem frekvenčnem pasu, kadar se dodeli fiksni storitvi v razponu 9 kHz do 300 GHz. Vendar se sistemi s temeljnim oddajanjem pod 30 MHz ne štejejo za primerne za digitalne fiksne radijske sisteme in so zunaj področja uporabe tega dokumenta. Ravni domene stranskih oddajanj in delovanje odpornosti pri antenskem vhodu so pomembne tudi za osnovne zahteve iz člena 3.2 Direktive 1999/5/ES [i.12] o radijski opremi in telekomunikacijski terminalski opremi (R&TTE). Ta dokument dopolnjuje Priporočilo CEPT/ERC 74-01 [4], ki navaja mejne vrednosti za neželena oddajanja v stranski domeni in se osredotoča zlasti na delovanje »med storitvami«, pri čemer je delovna skupina TM4 sklepala, da je v nekaterih primerih potrebna večja zaščita za združljivost med fiksnimi radijskimi sistemi, ki se uporabljajo na istem geografskem območju. Dodatni premisleki in osnovne informacije za pripravo tega dokumenta so na voljo v teh dokumentih:
– Priporočilo ITU-R SM.329 [1] obravnava oddajanja iz katerega koli sistema, vključno z digitalno modulacijo, ter dopušča možnosti za opredelitev frekvenčne razmejitve med zunajpasovno domeno in domeno stranskih oddajanj. Priporoča drugačne kategorije ravni mejnih vrednosti, ki se uporabljajo za fiksno storitev;
– Priporočilo ITU-R SM.1539 [2] opisuje uporabo koncepta razmejitve med zunajpasovno domeno in domeno stranskih oddajanj;

Major changes with respect to previous version This revision is consequent to recent revision of CEPT/ERC Recommendation 74-01 [4] and inclusion in other ETSI point-to-point standards of systems with bandwidth wider than 500 MHz, which have some different regulation in ECC/REC(02)05 [5] and Recommendation ITU-R SM.1539 [2]. Therefore alignment is needed on the following arguments: • Spurious emission domain limits for BWA systems in bands between 1 GHz and 6 GHz • Boundary between out of band and spurious domains for systems with bandwidths > 500 MHz • Updated of examples in clause B.2 SIST EN 301 390 V1.3.1:2013

ETSI ETSI EN 301 390 V1.3.1 (2013-08) 6 - a suitable and easy to perform criterion for DFRS receivers' immunity at antenna port may be considered the application of a CW interference. Some ETSI deliverables for DFRS, sometimes, provide limits for both "external" and "internal" spurious domain emissions and the latter are outside the scope of the present document. Moreover the limits for emissions given in the present document do not prevent more stringent requirement given in those deliverables for intra-system purpose (i.e. local Transmitter to Receiver interference usually referred as "internal"). In order to fix the suitable limits, in annex B, spurious domain emissions are analysed from the point of view of a suitable test method for conformance testing. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

NOTE 2:
Some channel arrangements give only a continuous raster of elementary frequency slots for composing multiple (N × elementary slot) aggregated channels of various size. In this case the actual CS would be equal to the N × elementary slot used by the radio system. When no channel arrangement or elementary slot raster is defined in the band of operation of the radio system, the occupied bandwidth should be considered in substitution of the CS.

For the purpose of the present document, β/2 is assumed to be equal to 0,5 % (Recommendation ITU-R F.1191 [3]). out-of-band domain (of an emission): frequency range, immediately outside the necessary bandwidth but excluding the spurious domain, in which out-of-band emissions generally predominate NOTE: Out-of-band emissions, defined based on their source, occur in the out-of-band domain and, to a lesser extent, in the spurious domain. Spurious emissions likewise may occur in the out-of-band domain as well as in the spurious domain. However, the limit in the out-of-band-domain applies to any unwanted emissions independently from their formal identification as out-of-band or spurious emissions. out-of-band emissions: any unwanted emission, outside the channel bandwidth, which falls at frequencies separated from the centre frequency of the emission by less than 250 % of the relevant channel separation, where the system is intended to be used.

See Recommendation ITU-R F.1191 [3]. receiver spurious emissions: spurious sent backwards to the antenna port by a receiver NOTE: Sometimes they are also referenced as "spurious radiations". reference bandwidth: bandwidth where the spurious emission limits are defined NOTE: See also Recommendation ITU-R SM.329-10 [1]. spurious domain (of an emission): frequency range beyond the out-of-band domain in which spurious emissions generally predominate NOTE: Spurious emissions may occur in the out-of-band domain as well as in the spurious domain. Likewise out-of-band emissions, defined based on their source, occur in the out-of-band domain and, to a lesser extent, in the spurious domain. However, the limit in the spurious-domain applies to any unwanted emissions independently from their formal identification as out-of-band or spurious emissions.

Tx Transmitter VSWR Voltage Standing Wave Ratio WRC World Radio Conference 4 Transmitter spurious domain emissions at antenna port According to Recommendation ITU-R SM.329 [1] and the application to fixed service provided by Recommendation ITU-R F.1191 [3], the spurious domain emissions limits are applied to unwanted emissions at frequencies which are, for channel separations ≤ 500 MHz, ±250 % of the relevant channel separation outside the nominal carrier frequency (spurious emission domain). SIST EN 301 390 V1.3.1:2013
ETSI ETSI EN 301 390 V1.3.1 (2013-08) 10 For channel separation > 500 MHz, according Recommendation ITU-R SM.1539 [2] and CEPT/ERC Recommendation 74-01 [4], the spurious domain emissions limits are applied to unwanted emissions at frequencies which are outside the nominal carrier frequency by more than ± (500 MHz + 150 % of the relevant channel separation expressed in MHz) of the relevant channel separation (spurious emission domain). According Recommendation ITU-R F.1191 [3], the Channel Separation (CS) is taken as XS/2 for alternated frequency channel arrangements and XS for co-channel and interleaved frequency channel arrangements as defined by Recommendation ITU-R F.746 [i.11]. The emission within ±250 %, or in case ± (500 MHz + 150 %), of the relevant channel separation (out-of-band domain) includes only fundamental and unwanted emissions in the out-of-band domain which are outside the scope of the present document. 4.1 Limits Unless more severe requirement were reported into a specific product ETSI deliverable, the unwanted emissions in the spurious domain delivered at antenna port, of both transmitter and receiver, of Fixed Radio Systems shall be limited within the average power limits reported below. For "noise-like" emissions, the limits are intended not to be exceeded in any elementary measuring bandwidth. The limit values are defined at reference point C' shown in the general RF block diagram of figure 1.

Foreword
This draft European Standard (EN) has been produced by ETSI Technical Committee Access, Terminals, Transmission
and Multiplexing (ATTM), and is now submitted for the combined Public Enquiry and Vote phase of the ETSI
standards EN Approval Procedure.
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
Major changes with respect to previous version
This revision is consequent to recent revision of CEPT/ERC Recommendation 74-01 [4] and inclusion in other ETSI
point-to-point standards of systems with bandwidth wider than 500 MHz, which have some different regulation in
ECC/REC(02)05 [5] and Recommendation ITU-R SM.1539 [2].
Therefore alignment is needed on the following arguments:
• Spurious emission domain limits for BWA systems in bands between 1 GHz and 6 GHz
• Boundary between out of band and spurious domains for systems with bandwidths > 500 MHz
• Updated of examples in clause B.2
ETSI

5 Draft ETSI EN 301 390 V1.3.0 (2013-04)
1 Scope
The term Spurious emissions is used for simplicity elsewhere in the present document but with the more broader
meaning of "unwanted emissions in the spurious domain" introduced by Recommendation ITU-R SM.329 [1] for
clarifying the Radio Regulation definitions and the application of recommended limits for all unwanted emissions; it
also recommends that spurious emissions limits apply to all unwanted emissions falling in the spurious domain.
Therefore the present document deals with limits for unwanted emissions in the spurious domain at antenna port of
Digital Fixed Radio Systems (DFRS) as defined by Recommendation ITU-R SM.329 [1] and CEPT/ERC
Recommendation 74-01 [4] and ECC Recommendation (02)05 [5].
Moreover it covers immunity characteristics at receiver's antenna port.
Scope of the present document is to define specific limits at antenna port for spurious emissions domain and receiver
immunity for suitable inter-working of Digital Fixed Radio Systems (i.e. Point-to-point and Multipoint systems) in the
same or in different frequency band whenever allocated to Fixed Service in the range 9 kHz to 300 GHz.
However systems with fundamental emission below 30 MHz are not considered relevant for Digital Fixed Radio
Systems and are outside the scope of the present document.
Spurious emissions domain levels and immunity performance at antenna port are also relevant to essential requirements
under article 3.2 of Directive 1999/5/EC [i.12] on Radio equipment and Telecommunication Terminals equipment
(R&TTE).
The present document complements CEPT/ERC Recommendation 74-01 [4] which gives limits for Unwanted
emissions in the Spurious domain with particular regards to "inter Services" operations, while WG TM4 assumed that in
some case more protection is required for compatibility among fixed radio systems deployed in the same geographical
area.
Additional considerations and background for producing the present document are:
- Recommendation ITU-R SM.329 [1] considers emissions from any system, including digital modulation and
allows options for the definition of the frequency boundary between out-of-band domain and spurious
emissions domain. It recommends different category of level limits applicable to the Fixed Service;
- Recommendation ITU-R SM.1539 [2] describes the application of the boundary concept between
out-of-band and spurious emission domains;
- Recommendation ITU-R F.1191 [3] define the application of Radio Regulations [i.13] and SM set of
Recommendation ITU-Rs concepts of out-of-band, unwanted and spurious emissions to DFRS, clarify the
applicability for the boundary between out-of-band and Spurious emissions domains but maintain the same pos
sible limit options provided by ITU-R Recommendation SM.329-10 [1];
- CEPT/ERC Recommendation 74-01 [4], endorses only the more stringent Category B limits of
Recommendation ITU-R SM.329-10 [1];
- after the coming into force of RTTE Directive [i.12] the emissions and immunity at antenna port fall under its
article 3.2 requirements for "effective use of spectrum" and "avoidance of harmful interference" and they are
no longer an EMC requirement;
- it is convenient to maintain a single EN covering these parameters instead of replicating them on each single
product standard, avoiding possible deviation from what required by other CEPT and ITU-R normative;
- limits for unwanted emissions in the spurious domain are supposed to be fixed in view of inter-working
compatibility among various Fixed Radio Systems in same or different band exploited in the same area;
- the measurement of the required limits should also be feasible in a suitable and cost effective conformance test
(annex B gives also information in this field);
- it is necessary that DFRS receivers provide a minimum level of immunity at antenna port towards possible
interference at any frequency band of practical interest;
ETSI
---------------------- Page: 5 ----------------------
6 Draft ETSI EN 301 390 V1.3.0 (2013-04)
- a suitable and easy to perform criterion for DFRS receivers' immunity at antenna port may be considered the
application of a CW interference.
Some ETSI deliverables for DFRS, sometimes, provide limits for both "external" and "internal" spurious domain
emissions and the latter are outside the scope of the present document. Moreover the limits for emissions given in the
present document do not prevent more stringent requirement given in those deliverables for intra-system purpose
(i.e. local Transmitter to Receiver interference usually referred as "internal").
In order to fix the suitable limits, in annex B, spurious domain emissions are analysed from the point of view of a
suitable test method for conformance testing.

evaluation bandwidth: bandwidth where the spurious domain emission limits are measured (e.g. the spectrum analyser
resolution bandwidth) for further normalization/integration to the reference bandwidth
Broadband wireless access (BWA) system: access system used for the deployment of radio access networks in both
the fixed service and the mobile service
Channel Separation(CS): distance between adjacent channels in a radio frequency channels arrangement (defined in
ECC or ITU-R or national recommendations)
NOTE 1: it represents one of the major parameters for the identification of the radio equipment use and relevant
requirements.
NOTE 2: Some channel arrangements give only a continuous raster of elementary frequency slots for composing
multiple (N × elementary slot) aggregated channels of various size. In this case the actual CS would be
equal to the N × elementary slot used by the radio system. When no channel arrangement or elementary
slot raster is defined in the band of operation of the radio system, the occupied bandwidth should be
considered in substitution of the CS.

occupied bandwidth: width of a frequency band such that, below the lower and above the upper frequency limits, the
mean powers emitted are each equal to a specified percentage β/2 of the total mean power of a given emission (Radio
Regulations [i.13])
NOTE: For the purpose of the present document, β/2 is assumed to be equal to 0,5 %
(Recommendation ITU-R F.1191 [3]).
out-of-band domain (of an emission): frequency range, immediately outside the necessary bandwidth but excluding
the spurious domain, in which out-of-band emissions generally predominate
NOTE: Out-of-band emissions, defined based on their source, occur in the out-of-band domain and, to a lesser
extent, in the spurious domain. Spurious emissions likewise may occur in the out-of-band domain as well
as in the spurious domain. However, the limit in the out-of-band-domain applies to any unwanted
emissions independently from their formal identification as out-of-band or spurious emissions.
out-of-band emissions: any unwanted emission, outside the channel bandwidth, which falls at frequencies separated
from the centre frequency of the emission by less than 250 % of the relevant channel separation, where the system is
intended to be used.
NOTE: See Recommendation ITU-R F.1191 [3].
receiver spurious emissions: spurious sent backwards to the antenna port by a receiver
NOTE: Sometimes they are also referenced as "spurious radiations"
reference bandwidth: bandwidth where the spurious emission limits are defined
NOTE: See also Recommendation ITU-R SM.329-10 [1].
spurious domain (of an emission): frequency range beyond the out-of-band domain in which spurious emissions
generally predominate
NOTE: Spurious emissions may occur in the out-of-band domain as well as in the spurious domain. Likewise
out-of-band emissions, defined based on their source, occur in the out-of-band domain and, to a lesser
extent, in the spurious domain. However, the limit in the spurious-domain applies to any unwanted
emissions independently from their formal identification as out-of-band or spurious emissions.
spurious emissions: any unwanted emission which falls at frequencies separated from the centre frequency of the
emission by 250 % or more of the relevant channel separation, where the system is intended to be used

4 Transmitter spurious domain emissions at antenna
port
According to Recommendation ITU-R SM.329 [1] and the application to fixed service provided by
Recommendation ITU-R F.1191 [3], the spurious domain emissions limits are applied to unwanted emissions at
frequencies which are, for channel separations ≤ 500 MHz, ±250 % of the relevant channel separation outside the
nominal carrier frequency (spurious emission domain).
ETSI
---------------------- Page: 9 ----------------------
10 Draft ETSI EN 301 390 V1.3.0 (2013-04)
For channel separation > 500 MHz, according Recommendation ITU-R SM.1539 [2] and CEPT/ERC Recommendation
74-01 [4], the spurious domain emissions limits are applied to unwanted emissions at frequencies which are outside the
nominal carrier frequency by more than ± (500 MHz + 150 % of the relevant channel separation expressed in MHz) of
the relevant channel separation (spurious emission domain).
According Recommendation ITU-R F.1191 [3], the Channel Separation (CS) is taken as XS/2 for alternated frequency
channel arrangements and XS for co-channel and interleaved frequency channel arrangements as defined by
Recommendation ITU-R F.746 [i.11].
The emission within ±250 %, or in case ± (500 MHz + 150 %), of the relevant channel separation (out-of-band domain)
includes only fundamental and unwanted emissions in the out-of-band domain which are outside the scope of the
present document.
4.1 Limits
Unless more severe requirement were reported into a specific product ETSI deliverable, the unwanted emissions in the
spurious domain delivered at antenna port, of both transmitter and receiver, of Fixed Radio Systems shall be limited
within the average power limits reported below.
For "noise-like" emissions, the limits are intended not to be exceeded in any elementary measuring bandwidth.
The limit values are defined at reference point C' shown in the general RF block diagram of figure 1.

NOTE: For coherency CEPT/ERC Recommendation 74-01 [4] considers a unique limit for BWA systems
independently from the use of the stations for fixed or mobile traffic (or for both when MS are
