Scope
The present document specifies the essential electrical requirements for linear polarization fixed beam antennas to be utilized with new Point-to-Multipoint (P-MP) systems@ including central station and terminal station applications@ operating in frequency bands from 1GHz to 3 GHz. These systems use various multiple access schemes. Electronically steerable antennas@ and circularly polarized antennas are not considered under the present document. Only in exceptional circumstances@ and after a consultation period with operators and manufactures@ the Regulatory Authority may impose the use of tighter requirements then the minimum values given in the present document@ in order to maximize the use of scarce spectrum resources. The application of these radio systems is anticipated to be for point-to-multipoint links in local access networks and customer access links. For some high gain@ point-to-multipoint requirements antennas may be used having performance as per the appropriate point-to-point antenna standard. For these antennas@ minimum requirements are given in [6].
