The purpose of this paper is to examine the possibility of increasing the downlink E.I.R.P. density limits for operation of Fixed Satellite Service (F.S.S.) links in the Ku band. The Ku band is extensively used for voice, video, data, remote sensing applications and for transmission to VSAT (Very Small Aperture Terminals) networks. However, the limit on downlink E.I.R.P. density is considered to be conservative and it's assumed that much higher E.I.R.P. densities should be possible without causing significant interference to adjacent users. If this is proved, it would be possible to achieve lower Bit Error Rates and thereby increase reliability of satellite links. The increased power transmission capability would also allow transmission of more signals with the available bandwidth or lead to reduction in size of receiving antennas. With the help of existing F.C.C. limits on antenna gain patterns and the I.T.U. interference criterion, an increase in downlink E.I.R.P. density per carrier by more than 66% is shown to be possible. This increase in power would dramatically affect Fixed Satellite Services.
