适用范围
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 theseDigtal Radio Relay Systems (FRS) 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 consulation period with operators and manufactures@ aRegulatory 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.
