Transmission and Multiplexing (TM); Digital Radio Relay Systems (DRRS); Part 2: Antennas for Point-to-Multipoint (P-MP) Radio Links in the 1 GHz to 3 GHz Band
|Publication Date:||1 May 1999|
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 .
