1 Scope
The present document, is intended for complementing the EG 201 399 [i.1] for specific guidance related to Digital
Fixed Radio Systems (DFRS) in the production of candidate harmonized standards under the Council Directive
1999/5/EC [i.2] (commonly identified as the R&TTE Directive). Consequently the present document should always be
used in conjunction with EG 201 399 [i.1] whenever DFRS are concerned.
The present document identifies, among the generic attributes and technical phenomena, relevant for the article 3.2 of
the Directive [i.2], presently quoted by EG 201 399 [i.1], those which are relevant and applicable, for the various
typologies of Fixed Digital Radio Systems.
Moreover it gives the cross reference from the generic terminology used in EG 201 399 [i.1] and that currently used
within the Fixed Radio technical community.
Considerations about attributes and technical phenomena related to articles 3.1 (health, safety and EMC) and 3.3
(interworking and other special requirements) of the R&TTE Directive [i.2] are outside the scope of the present
document.

4 General principles
The objective of a Harmonized Standard under the R&TTE Directive [i.2] for a DFRS is to define clear and
unambiguous provisions for the essential requirements referred in the Directive, which are applicable to the system
concerned.
To aid the ETSI Technical Bodies in the production of candidate harmonized standards, ETSI produced the
EG 201 399 [i.1] that expands the general concepts of essential requirements into a more detailed subdivision and gives
guidance for categorizing Telecommunication Terminal Equipment (TTE) and Radio Equipment (RE) in order to
identify the technical phenomena relevant to the essential requirement under consideration.
However, particularly in the parts that refer to article 3.2 "The effective use of the radio spectrum" of the R&TTE
Directive [i.2], also EG 201 399 [i.1] uses terminology and concepts that, when applied to a specific family of radio
systems such as the Fixed Radio, proves to be still too generic; therefore further guidance, more technically based on
the technology and terminology used by the relevant technical community, is reported in the present document.
Therefore the present document should always be used in conjunction with the EG 201 399 [i.1] whenever Fixed Digital
Radio Systems (DFRS) are concerned.

5 Application of Equipment Attributes in EG 201 399 to
Digital Fixed Radio Systems (DFRS)
5.1 Equipment Attributes
Presently EG 201 399 [i.1] defines the following attributes for Radio Equipment (RE) and Telecommunication
Terminal Equipment (TTE) or both:
a) RE that is unable to transmit before receiving an appropriate enabling signal under any circumstances.
b) RE that is able to transmit without receiving an appropriate enabling signal.
c) RE capable of receive only.
d) Apparatus intended for use in "Emergency applications".
e) Short range radio transmitting devices.
f) RE intended for installation in sites which may be shared with other RE without co-ordination from a single
operator.
g) RE sharing radio spectrum resources with or without operational co-ordination.
h) TTE using an electrical interface for communication.
i) TTE using an optical interface for communication.
j) RE using received signal (e.g. the receiver level) to control transmitter power level or channel access
(automatically or manually).
5.2 Equipment attributes and their applicability to DFRS
5.2.1 Attribute A: RE that is unable to transmit before receiving an
appropriate enabling signal under any circumstances
This attribute is typical of systems like GSM, of which terminals of different manufacturer can be connected at any time
to a BTS; in this case the radio frequency interface is standardized in GSM coexistence standards and air interface
interoperability.
Even without requirement for air interface interoperability, some MP terminals need granting from CRS, however, in
this case, the enabling signal still is an "intra system" feature, therefore not relevant from the point of view of the
essential requirements under the R&TTE Directive [i.2].
This attribute would be relevant for DFRS only in the case of standards that would possibly be developed requiring air
interface interoperability.
The analysis of the relevant phenomena is left for further study, if required.
5.2.2 Attribute B: RE that is able to transmit without receiving an
appropriate enabling signal
In principle conventional DFRS transmit without enabling signals. However, in order to avoid harmful or unacceptable
interference and to ensure the efficient use of the spectrum in not harmonized frequency bands, allocated to the Fixed
Service, national frequency co-ordination and link by link licensing is applied. In not harmonized and not co-ordinated
bands (e.g. 58 GHz) the argument is not relevant.
The "national licensing" may be considered as an "enabling signal" of different nature, therefore this attribute is
considered not relevant for conventional DFRS.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TR 101 506 V1.3.1 (2010-01)
Presently, for DFRS, this attribute could be relevant only to transportable equipment for provisional links (in the event
that the national licensing policy is different from permanent links). This type of equipment is in general not considered
specifically in WG TM-4 standards, but is possibly offered independently by suppliers to specific customers as not
standardized options.
The analysis of the relevant phenomena is left for further study, if required.
5.2.3 Attribute C: RE capable of receive only
This attribute is presently considered not relevant for DFRS presently standardized in WG TM-4, because DFRS applies
only to telecommunications.
5.2.4 Attribute D: Apparatus intended for use in 'Emergency applications'
This attribute is also more detailed in the EG 201 399 [i.1] as "Equipment having this attribute requires a high assurance
of performance when operating".
From the applicable essential phenomena point of view, this attribute is one of the two that presently require as essential
phenomena the "(Maximum usable) sensitivity (including duplex)" and the only one requiring "co-channel rejection";
these parameters are commonly required for frequency co-ordination purpose in order to guarantee the link performance
and availability.
It is commonly understood that when used in PCN (Public Communication Networks), DFRS, as all other media
equipment, should meet a number of ITU-T and ITU-R performance and availability recommendations
(e.g. ITU-T Recommendations G.826 [i.3], G.827 [i.4] and ITU-R Recommendations F.1668 [i.7], F.1703 [i.8],
F.1565 [i.6]), which are essential for national and international communications that may commonly include any kind of
high priority government, business and emergency communications.
It is also noted that, having the fulfilment of those ITU requirements implies the definition, for each link, of a
well-defined fade-margin, which is composed by the Tx Pout as well as by the RX minimum sensitivity. Therefore,
poor RX sensitivity and co-channel rejection, beyond a minimum standardised requirement, would require a
correspondent higher Tx power with potential increase of the probability of causing harmful interference to other users
of the band.
Therefore it is considered that, for P-P and MP equipment used in the "public core and access networks", carrying
traffic which includes conventional voice telephony and "high performance leased lines option" this attribute is
applicable.
For equipment intended only for "residential access network" (where entertainment and commercial traffic may
dominate) and private networks, the subject is left to a case-by-case analysis.
By the nature and usage of not co-ordinated bands (e.g. 58 GHz band referenced in CEPT/ERC
Recommendation 12-09 [i.14]), equipment designed for these bands, are not considered suitable for this attribute.
5.2.5 Attribute E: Short range radio transmitting devices
This attribute is not relevant for DFRS.
5.2.6 Attribute F: RE intended for installation in sites which may be shared
with other RE without co-ordination from a single operator
This attribute is specifically referred by EG 201 399 [i.1] as applicable to DFRS.
However at least one other attribute should accompany this attribute.
The suggested phenomena for this attribute, to be considered in defining essential requirements, cover only transmitter
and receiver intermodulation, which are a consequence of the shared installation site, not elsewhere covered by other
equipment specific attributes.
ETSI

---------------------- Page: 10 ----------------------
11 ETSI TR 101 506 V1.3.1 (2010-01)
The justification for differentiation of this attribute is principally because the equipment is stationary and thus if any
problems do arise the assumption should be that the problem is permanent and thus may permanently degrade the
intended usage.
Examples of such equipment "sharing" the same site or its close vicinity are base stations of any type, fixed link stations
broadcast transmitters, and pager stations.
Also other receiver intermodulation effects might become more important. Due to a possible large number of antennas
and DFRS types, installed at the same site or in close vicinity to an existing site, the interference from "unwanted"
emissions may become more critical.
However the traditional mitigation solutions of antenna filters, circulators, etc are commonly used in DFRS; in addition,
the frequency coordination, in use among other DFRS, avoids the presence of high Tx carrier power in close vicinity of
RX, unconventional solutions, possible for solving uncommon network problems, are usually treated on a case-by-case
bases with site-engineering procedure. Therefore, this attribute is not generally applicable to DFRS.
5.2.7 Attribute G: RE sharing radio spectrum resources with or without
operational co-ordination
DFRS need this attribute differentiation for coexistence with similar systems deployed in the same geographical area
and using the same frequency band.
This attribute is the most appropriate for DFRS and contains most of the radio frequency co-ordination parameters,
including antenna parameters.
Logically, for bands not requiring co-ordination, a reduced sub-set of receiver and antenna essential parameters is
required in comparison to those required for co-ordinated bands.
5.2.8 Attribute H: TTE using an electrical interface for communication
The phenomena list for this attribute is presently empty.
A radio equipment may have also an electrical interface towards the network or user side. When the equipment is also
considered a TTE (see de
