scope:

The present document addresses the requirements for directional fixed beam antennas to be utilized with new Point-to- Point (P-P) systems operating in the frequency band 1 GHz to 3 GHz. Electronically steerable antennas, and circularly polarized antennas will not be considered under the present document.

The application of these Digital Radio Relay Systems (DRRS) is anticipated to be for P-P links in local, regional and national networks, mobile base station connections, customer access links, telemetering and telecontrol (including transportable and offshore use).

Only in exceptional circumstances, after a consultation period with operators and manufactures, a Regulatory Authority may impose tighter requirements than the minimum values given in the present document, in order to maximize the use of the scarce spectrum resources.
