Broadband access by satellite in Ka band is currently constrained by spectrum availability. In this context, the EU FP7 project CoRaSat is examining the possible ways in which improved frequency utilization could be possible in Ka band via the use of cognitive mechanisms. A database approach utilizing spectrum scenarios between Fixed Satellite Services (FSS), Fixed Services (FS) and Broadcast Satellite Service (BSS) feeder links are considered. Interference in the downlink from BSS and FS are evaluated using real data bases and propagation models. Data base statistics for several EU countries are also evaluated. The importance of using correct terrain profiles and accurate propagation models is shown. For the case of the BSS interference to the FSS downlink it is demonstrated that for the UK an area of less than 2% is affected and thus the additional 400 MHz spectrum band (17.3 to 17.7 GHz) can be used by FSS over the majority of the country. The operational challenges of the database approach across the EU are also discussed.
