Effects of deploying IMT-Advanced systems on fixed satellite services in the 3 400 – 3 600 MHZ frequency band in Pakistan

This paper investigates the effects of deploying International Mobile Telecommunication-Advanced (IMT-Advanced) systems in the 3 400 - 3 600 MHz frequency band in Pakistan. This allocation of C-band spectra is being used by Paksat-1 for fixed satellite services (FSS). In addition future Paksat satellite networks will use the same C-band spectra for their FSS. The sharing studies b/w IMT-Advanced systems and GSO satellite networks in FSS show the incompatibility between them. To provide protection of the FSS receive earth stations, some separation distance between the stations of the IMT-Advanced network and the FSS receive earth stations is required. This issue was also on the agenda for the World Radio Communication Conference (WRC-2007) meetings in Geneva under item 1.4. The final provisional acts of WRC-2007 states that the band 3 400 - 3 600 GHz is identified for potential use of IMT-Advanced systems in Pakistan.
