Analysis of interference between terrestrial and satellite systems in the Band 17.7 to 19.7 GHz

Abstract

Broadband access by satellite in the Ka-band is currently constrained by spectrum availability. Very high throughput satellite systems are being proposed that operate in the Ka-band spectrum that is allocated to both Fixed Satellite Services (FSS) and Fixed Services (FS). This paper addresses a database approach to exploiting the dual use of the band 17.7 to 19.7 GHz. Interference from the FS has been analysed using real data bases and appropriate propagation models. Database statistics for several European Union (EU) countries were also evaluated. The importance of using accurate terrain profiles and accurate propagation models are discussed and some results shown.
