Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Access, Terminals, Transmission and
Multiplexing (ATTM).
Major variants with respect to previous published version:
• alignment of terminology and system identification method to latest version of EN 302 217-2-2 [i.4];
• introduction of typical parameters also for bands above 55 GHz (i.e. 60 GHz and 71 GHz to 86 GHz);
• updating due to technology evolution.
Introduction
As a consequence of the development of the multipart EN 302 217 [i.2] to [i.7], which was intended to supersede a
number of older point-to-point equipment and antenna ENs, hereby referenced as "source ENs", all previous
requirements have been reconsidered in the light of Directive 1999/5/EC (R&TTE Directive) [i.1] in order to clearly
split them between those that are relevant to article 3.2 of R&TTE Directive [i.1] and other requirements of normative
nature (as in previous regime before R&TTE Directive coming into force) or even considered informative for the EN
users.
In particular EN 302 217-2-2 [i.4] and EN 302 217-3 [i.5] recognized that, besides frequency band around 60 GHz,
where oxygen absorption becomes very high, and cases specifically mentioned in Radio Regulations [i.13], limits for
TX output power do not fall in any of the above categories. Regulatory bodies are generally fixing limits for the
licensing but no ECC common view is expressed in any ECC Decision; on the other hand it is not ETSI's role to impose
limits to technology evolution and market demands.
As a consequence the "maximum" power figures, historically fixed in those older "source ENs", have been removed
from the requirements in EN 302 217-2-2 [i.4] and EN 302 217-3 [i.5], which ask for "supplier declaration" of actual
TX power and its tolerance to be used as limits for assessment against R&TTE Directive [i.1], article 3.2 requirements.
However, those values were often used as a basis for intra and inter-services coexistence and sharing studies. It was
therefore considered that information about "typical-maximum" TX power (i.e. those coming from practical technology
and practical system deployment constraints) would still be usefully maintained in the present document for any such
purpose.
Having removed them from regulatory HEN "hard-limits", the present document gives information more close to actual
reality of Fixed Service (FS) currently deployed; this would lead to much more balanced sharing studies and planning
assumptions, leaving only very few cases, potentially exceeding those values to real "special cases" to be treated on a
case-by-case basis according the principles of "proportionality" introduced by the "New Approach" set of EU
Directives.
Together with TX power information, it was considered necessary to also give similar antenna gain information for the
definition, of "typical-maximum" E.I.R.P. that, in the same fashion, would give the complete information needed for the
mentioned sharing/planning studies.

5 ETSI TR 102 243-1 V1.2.1 (2013-07)
In the band 57 GHz to ~ 64 GHz the peak value of the O ray absorption results in very specific propagation conditions
2
with a high potential of frequency reuse; for this reason CEPT has approved ECC/REC(09)01 [i.9] (superseding
previous ERC Recommendation 12-09 [i.8] limited to 57 GHz to 59 GHz band only) for an uncoordinated use of the
band or with simplified link notification procedures. No additional regulatory requirements have been set for P-P
applications; however, as frequency optimization mechanism, EN 302 217-3 [i.5] considers in its scope only equipment
that fulfils minimum E.I.R.P./Antenna gain joint profiles. In addition, manufacturers are free to implement other
network optimization features (e.g. automatic channel selection).
The bands 71 GHz to 76 GHz and 81 GHz to 86 GHz have also been open to P-P applications. Here the oxygen
absorption attenuation nullifies again and the band use might be considered similar to 38 GHz and 42 GHz bands when
taking into account the obvious increasing impact of rain attenuation; however, standing the very wide bandwidth
available and for stimulating the band deployment, different policies might be applied in different CEPT countries.
From the ETSI standards point of view, the band is considered to be either conventionally coordinated or with
simplified coordination (self coordinated with simple notification in the links data-base) or even fully uncoordinated.
Manufacturers and/or administrations can refer either only to EN 302 217-3 [i.5] (i.e. for the minimum requirements
when the band is not conventionally coordinated) or also to EN 302 217-2-2 [i.4] (i.e. for the additional requirements
needed for link-by-link coordination).

1 Scope
The present document summarizes, in relation to the various frequency bands and sub-system types given in the
multipart EN 302 217 [i.2] to [.i.7], information in relation to current practical bounds coming from technology and
deployment practice about:
• Typical-maximum TX power (see note).
• Typical-maximum antenna size and gain.
• Exceptional antenna size and gain.
NOTE: This should not be intended as the power delivered by equipment currently on the market; it indicates the
level that is reasonably achievable by FS technology in each band and might be rendered available
standing suitable market opportunities justifying the cost/benefit trade off.
Antenna gain is also related to its expected typical antenna size, which nowadays, for its ambient impact, is another
important factor limiting, in practice, most of FS deployments.
The above values are here reported here due to a lack of any ECC harmonized regulations. In the event that such ECC
regulations would come into force, it would supersede any less restrictive information given in the present document.
In the band 57 GHz to 64 GHz CEPT promotes an uncoordinated or simplified use of the band as outlined in ECC
Recommendation (09)01 [i.9]. Also in the band 64 GHz to 66 GHz ECC Recommendation (05)02 [i.10] provides for
simplified channel arrangement suitable for simplified regulatory approach (e.g. light licensing/notification).
In the bands 71 GHz to 76 GHz and 81 GHz to 86 GHz ECC Recommendation (05)07 [i.11] provides flexible
arrangements suitable for both simplified regulatory approach (e.g. light licensing/notification) or conventional
coordination; CEPT administrations would freely select the approach best fitting their policy for the bands.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
absolute maximum transmitter power: maximum permitted power requested in point-to-point ENs, which constitute
the "source ENs" for the multipart EN 302 217 series (see summary in annex C of EN 302 217-1 [i.2])
NOTE: It was judged as "not relevant" to "essential parameters" under article 3.2 of the R&TTE Directive [i.1],
and removed from the requirements in the Harmonized EN 302 217-2-2 [i.4]. It is assumed that no system
in the past might have exceeded that value.
exceptional size/gain: maximum antenna dish size and its practical associated gain that are still found in most antenna
supplier standard catalogues (at the date of publication of the present document)
NOTE: It then excludes any possible special design dedicated to a specific link.
typical maximum output power: typical current (i.e. only for recent and new deployment of systems potentially
available on the market) maximum power achievable in point-to-point FS technology
NOTE: In the present document it is separately indicated for the various systems defined in EN 302 217-2-2 [i.4].
