Transmission and Multiplexing (TM); Multipoint equipment; Radio equipment for use in Multimedia Wireless Systems (MWS) in the frequency band 40,5 GHz to 43,5 GHz; Part 2: Harmonized EN covering essential requirements under article 3.2 of the R&TTE Directive

Addition of part 2 to the 40 GHz MWS standard, to include essential harmonised parameters under the R&TTE Directive 1999/05/EC  Equipment performance characteristics and parameters necessary to facilitate coexistence between broadband Multimedia Wireless Systems (MWS) in either; adjacent frequency assignments in the same geographical area or co-frequency assignments in neighbouring geographical areas.  Multimedia Wireless Systems are defined  as terrestrial multipoint systems which have their origin in telecommunication and/or broadcasting, and which provide fixed wireless access direct to the end user for  multimedia services. These MWS systems may offer different degrees of interactivity.Therefore systems are anticipated that could deliver services requiring either asymmetric data rates, (including uni-directional distribution systems) or symmetric data rates between uplink and downlink. Any asymmetry between uplink and downlink may be fixed or dynamically variable to suit the traffic characteristics at any time.  This standard covers equipments that operate within the frequency band 40.5 to 43.5 GHz.  The general equipment parameters will be described in Part 1 of the standard  The essential harmonised parameters under the R&TTE Directive will be specified in Part 2 of the standard.

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 [1] 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").

The present document is part 2 of a multi-part deliverable covering Transmission and Multiplexing (TM); Multipoint

equipment; Radio equipment for use in Multimedia Wireless Systems (MWS) in the frequency band 40,5 GHz to

43,5 GHz, as identified below:
Part 1: "General requirements";

Part 2: "Harmonized EN covering essential requirements under article 3.2 of the R&TTE Directive".

Multimedia Wireless Systems (MWS) in the band 40,5 GHz to 43,5 GHz are described in EN 301 997-1 [13]. Antenna

systems suitable for use in MWS are described in EN 301 215-3 [3].

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [1].

For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present

document essential requirements in these areas have to be adopted by the Commission. If such essential requirements

are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to

be specified by function or interface type.

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, the multi-part product EMC standard for radio used under the EMC

Directive.

For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive 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 [1] 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 [1] 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

The present document applies to Multimedia Wireless Systems (MWS) in the band 40,5 GHz to 43,5 GHz, which

operate in block assignments, according to ECC/REC 01-04 [19]. It includes those parameters considered to be essential

under article 3.2 of the Directive 1999/5/EC [1], 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". Where equipment is intended for operation other than as specified in ECC/REC 01-04 [19] there

may be additional requirements outside the scope of the present document.

The relevant equipment parameters in EN 301 997-1 [13] are referenced as well as antenna parameters in

EN 301 215-3 [3]. These standards also contain other requirements that are not considered essential for the

R&TTE Directive [1], but are nevertheless recommended on a voluntary basis to meet relevant network performance

objectives as defined by international standardizing bodies.

A wide range of Multimedia Wireless Systems (MWS) is possible. The present document covers a range of alternatives,

for which the access methods and corresponding test requirements are specified in available relevant ETSI standards

and referred to in EN 301 997-1 [13]. Similarly, antennas other than those specified in available and relevant ETSI

standards may also be proposed.

A range of antenna and equipment types and corresponding test methods are covered by the present document.

However, it should be noted that, national regulatory bodies, according to article 7.2 of Directive 1999/5/EC [1] may,

for the purpose of local licensing, limit the options permitted.

For system variants that do not use the access methods or do not meet the ETSI specified parameters for equipment in

EN 301 213-1 [14], EN 301 213-2 [15], EN 301 213-3 [16], EN 301 213-4 [17], EN 301 213-5 [18] or antennas in

EN 301 215-1 [2], EN 301 215-3 [3], CE marking may also be possible via one of the alternative routes described in the

Directive 1999/5/EC [1].

3 Definitions, symbols and abbreviations
3.1 Definitions

For the purposes of the present document, the following terms and definitions apply:

allocated radio frequency band: entry in the table of frequency allocations of a given frequency band for the purpose

of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specific

conditions

NOTE: This term shall also be applied to the frequency band concerned (ITU Radio Regulations article 1,

No. 17).

Automatic Transmit Power Control (ATPC): function to offer a dynamic power control that delivers the maximum

power only during deep fading activity; in this way, for most of the time, the interference is reduced and the transmitter

operates in a higher linearity mode

NOTE: When this function is used the transmit power is dynamically changed and follows the propagation

condition. In principle when ATPC is implemented three different level of power may be identified:

Maximum available power (delivered only in a condition of deep fading).

Maximum nominal and maximum available power levels may be coincident or in case of

multi-state modulation formats the maximum available power may be used to overdrive the

transmitter (losing linearity but gaining fade margin when the fade conditions have already

impaired the expected RBER). Performance prediction is usually made with the highest "available

power".

Maximum nominal power (useable on permanent base when ATPC is disabled); it should be noted

that this power is "nominal for the equipment" and has not to be confused with the "nominal level

set link by link" by the frequency co-ordination body, eventually achieved through passive RF

attenuators or RTPC function.
Minimum power (delivered in unfaded condition).

conformity assessment procedure: See Directive 1999/5/EC [1], annexes II, III, IV and V.

environmental profile: range of environmental conditions under which equipment, within the scope of the present

document, is required to comply with the provisions of EN 301 997-2

essential phenomenon: radio frequency phenomenon related to the essential requirements under article 3.2 of the

Directive 1999/5/EC that is capable of expression in terms of quantifiable technical parameters

harmonized radio frequency band: commonly referred as a portion of the frequency spectrum that CEPT/ERC

allocates to a specific service through a CEPT/ERC Decision (proper definition is currently under study by CEPT/ERC)

NOTE: Presently radio frequency bands allocated to Fixed Service are not harmonized.

maximum available power: See Automatic Transmit Power Control (ATPC).
maximum nominal power: See Automatic Transmit Power Control (ATPC).

national radio frequency channel arrangement: predefined centre frequencies raster for a number of radio frequency

channels covered by a national regulation in a not harmonized frequency band used in a country (it may all or in part

overlap with other national or recommended radio frequency channel arrangements)

operating frequency range: range(s) of radio frequency channels covered by the Equipment Under Test (EUT)

without any change of HW units

radio equipment: product or relevant component thereof capable of communication by means of the emission and/or

reception of radio waves utilizing the spectrum allocated to terrestrial/space radio communication

NOTE: See article 2 of Directive 1999/5/EC [1].

radio frequency channel: portion of a radio frequency band where a radio frequency channel arrangement has been

established, dedicated to one fixed radio link (or a P-MP system sector)

radio frequency channel arrangement: predefined centre frequencies raster for a number of radio frequency channels

used by administrations for co-ordination in the same geographical area
NOTE: Radio frequency channels are defined by ITU-R Recommendation F.746 [20].

recommended radio frequency channel arrangement: predefined centre frequencies raster for a number of radio

frequency channels, covered by a CEPT/ERC Recommendation in a not harmonized frequency band (not used for the

same purpose by all administrations) that is recommended to the member countries in the case they use the relevant

frequency band for Fixed Service

NOTE: Currently, CEPT does not recommend a radio frequency channel arrangement for the 40 GHz frequency

band.

Remote Frequency Control (RFC): function allowing to change and control the transmit/receive centre

frequency/channel either by a local monitoring terminal connected to the system or a by a remote network management

terminal

NOTE: The frequency variation is static and usually made to adapt the frequency of the link to the interference

scenario in the same geographical area. It is also used at the activation or re-commissioning of links in

order to easily obtain the licensed frequency assigned by the co-ordinator body to the network operator

for that link.

Remote Transmit Power Control (RTPC): function allowing to change and control the transmitter output power

either by a local monitoring terminal connected to the system or a by a remote network management terminal

NOTE: The transmitter power variation is static and usually made at the activation or re-commissioning of links

in order to easily obtain the EIRP required by the frequency co-ordination body for that link to control

co-channel and adjacent channel interference in the same geographical area. In principle, this function is

equivalent to the requirement of power regulation capability (e.g. by fixed attenuators) commonly

required in fixed systems.
