General
The present document is applicable to antennas (stand-alone, dedicated or integral antennas according to the definitions of terms in clause 3.1) used in MultiPoint (MP) Digital Fixed Radio Systems (DFRS) (see note 1) intended for use in the frequency bands identified in ETSI EN 302 326-2 [i.4].
NOTE 1: 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.3], are also considered in the scope of the present document.
For Multipoint Fixed Radio Systems, antenna characteristics are not considered relevant to essential requirements under article 3.2 of Directive 2014/53/EU [i.1] (see note 2). Antenna characteristics in the present document are considered applicable whenever they are considered appropriate for the associated multipoint radio system.
NOTE 2: Rationale can be found in ETSI TR 101 506 [i.2].
Antenna types and operating frequency
The present document is applicable to multipoint radio system antennas of both linear (single or dual) polarization and circular (single or dual) polarization. Linear polarization antennas may support either or both of two mutually perpendicular planes of polarization. These planes are frequently, though not always, horizontal and vertical. Circular polarization antennas may support either right hand or left hand polarization or, for dual polarization, both.
The RPE directional characteristics and polarization characteristics (co-polar and cross-polar and for either linear or circular polarized antennas) impact on the interference has to be considered in network planning. A number of antenna options are defined in the present document.
NOTE: Antenna characteristics are not standardized at frequencies below 1 GHz.
Profiles
The present document and associated ETSI EN 302 326-2 [i.4] for equipment and systems allows many distinct types of equipment, several different antenna types and several ways in which they might be interconnected to form a network. However, the applicability is limited to certain combinations of attributes and these combinations of attributes are called "profiles":
• Equipment profiles.
• Antenna profiles.
• System profiles.
Annex A discusses Equipment, Antennas and System Profiles for multipoint systems in the scope of this multi-part deliverable.
