V2.1.1

The present document specifies technical characteristics and methods of measurements applicable to radio equipment used in MultiPoint (MP) Digital Fixed Radio Systems (DFRS) (see note 2) designed for use in the following sub-ranges (see note 3):

• - 30 MHz to 1 GHz.
• - 1 GHz to 3 GHz.
• - 3 GHz to 11 GHz.
• - 24,25 GHz to 29,5 GHz.
• - 31,0 GHz to 33,4 GHz.
• - 40,5 GHz to 43,5 GHz.

NOTE 1 - The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU [i.1] is given in Annex A.

The present document is applicable to multipoint radio system equipment using any arbitrary access method. It applies to all equipment composing the MP systems, i.e. to Central Station (CS), Terminal Station (TS) and Repeater Station (RS).

Time Division Duplex (TDD) or Frequency Division Duplex (FDD or H-FDD) can be used on an equivalent basis.

Systems implementing an actual FH-CDMA access method with hopping period exceeding 400 ms are not considered within the scope of the present document.

NOTE 2 - Applications intended for offering in the bands 3,4 GHz to 3,8 GHz the option of Nomadic Wireless Access (NWA), according to the NWA definition in Recommendation ITU R F.1399 [i.14], are also considered in the scope of the present document.

NOTE 3 - For more information on the applicable frequency bands, refer to Annex F
