Fixed Radio Systems; Characteristics and requirements for point-to-point equipment and antennas; Part 2-1: System-dependent requirements for digital systems operating in frequency bands where frequency co-ordination is applied

Scope

The present document summarizes all system-dependent requirements for Point-to-Point (P-P) equipment in
applications deployed in bands where frequency co-ordination is generally applied. These requirements are introduced
in two different clauses sub-sets:
• Main requirements are requirements that are also related to the "essential requirements" under article 3.2 of
the R&TTE Directive [1] and further detailed in EN 302 217-2-2 [16].
• Complementary requirements are requirements that are not related to essential requirements under
article 3.2 of the R&TTE Directive [1]. Nevertheless they are considered having been commonly agreed for
proper system operation and deployment when specific deployment conditions or compatibility requirements
are present. Compliance to all or some of these requirements is made on a voluntary basis.
Description and limits for parameters relevant to essential requirements under article 3.2 of R&TTE Directive [1] are
given in EN 302 217-2-2 [16].
For other system-dependent parameters where standardization is required but that do not affect the R&TTE Directive
"essential requirements" mentioned above, description and limits are detailed in the present document in the annexes A
to G, subdivided by frequency band or specific applications.
The present document deals with Radio Frequency (RF) and base-band equipment characteristics; antenna system
requirements are covered in EN 302 217-4-1 (see bibliography) and EN 302 217-4-2 (see bibliography).
The present document does not cover test procedures and test conditions which are set out in EN 301 126-1 [14].
As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipment
classes are defined:
• Class 1: equipment spectral efficiency based on typical 2-states modulation scheme
(e.g. 2-FSK, 2-PSK or equivalent);
• Class 2: equipment spectral efficiency based on typical 4-states modulation scheme
(e.g. 4-FSK, 4-QAM, or equivalent);
• Class 3: equipment spectral efficiency based on typical 8-states modulation scheme
(e.g. 8-PSK, or equivalent);
NOTE: It is also noted that, in this class, for design commonality with other efficiency classes, the 16 QAM
format is popular).
• Class 4: equipment spectral efficiency based on typical 16-states or 32-states modulation scheme
(e.g. 16-QAM or 32-QAM, or equivalent);
• Class 5A: equipment spectral efficiency based on typical 64-states or 128-states modulation scheme
(e.g. 64-QAM or 128-QAM, or equivalent), for cross-polar adjacent channel (ACAP) operation;
• Class 5B: equipment spectral efficiency based on typical 64-states or 128-states modulation scheme
(e.g. 64-QAM or 128-QAM, or equivalent), for co-polar adjacent channel (ACCP) and frequency
reuse through CCDP operation;
• Class 6A: equipment spectral efficiency based on typical 256-states or 512-states modulation scheme
(e.g. 256-QAM or 512-QAM, or equivalent), for cross-polar adjacent channel (ACAP) operation;
• Class 6B: equipment spectral efficiency based on typical 256-states or 512-states modulation scheme
(e.g. 256-QAM or 512-QAM, or equivalent), for co-polar adjacent channel (ACCP) and frequency
reuse through CCDP operation.
The above classes are indicative only and do not imply any constraint to the actual modulation format, provided that all
the requirements in the relevant parts of this EN 302 217 series are met.

In some cases, where within the same spectral efficiency class there are different applications, (e.g. for multi-channel
trunk or single channel operation), that justify different radio frequency parameters, two different equipment "types"
(e.g. type 1 and 2) are provided.

R&TTE Directive [1] for DFRS may be found in TR 101 506 (see bibliography).
