ATSI (Advanced Technology Solutions International) was called in to assist an Egyptian gas company to replace their existing satellite communications network. The system was ineffective with frequent downtime, huge delay time and insufficient bandwidth to carry the traffic. There are also high costs associated with running the satellite communications system.
Microwave link conditions were challenging due to distance, and interference due to water in the link path that can lead to inconsistent performance.
ATSI decided to go with SAF PhoeniX split mount radio system:
SAF Teknika hardware was utilized to provide the best performance. A 1+1 space diversity (SD) setup was used and a separate ODU with antenna was deployed for each site to provide best link performance. This setup meant that the receiver could then pick out the better of the two received signals at two antennas, significantly reducing link multipath interference problems as well as avoiding links with weak RF receiving signals. SAF links were installed at 135 meter height on the onshore tower and at 25 meter height on the offshore tower – therefore overcoming the distance issues.
