V2.1.1

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 the Harmonized Standard 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 have 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 left to supplier decision.

Description and limits for parameters relevant to essential requirements under article 3.2 of R&TTE Directive [1] are given in the Harmonized Standard 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 clause 6 and in the annex A, annex F and annex G.

The present document deals with Radio Frequency (RF) and base band equipment characteristics; antenna system requirements are covered in EN 302 217 4 1 [i.9] and EN 302 217 4 2 [i.10].

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, equipment are subdivided in different spectral efficiency classes as defined in EN 302 217-2-2 [16].

The spectral efficiency 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 Multi-part deliverable for the declared class are met.

Guidance on the definition of radio parameters relevant to the essential requirements under article 3.2 of R&TTE Directive [1] for DFRS may be found in TR 101 506 [i.6].

Technical background for most of the parameters and requirements referred to in this Multi-part deliverable may be found in TR 101 036 1 [i.5]
