With a Ka-band Site Diversity configuration, the signal transmission is redirected from the Main Site to a Diverse Site in the case of adverse weather conditions. Site Diversity configurations, can employ DWDM RF-over-Fiber transmission systems and redundancy switching units, and provide and excellent way to ensure maximum Ka-band system reliability and availability, despite the high level of rain attenuation at Ka-band. The new RF-over-fiber technology, combined with wider availability of fiber lines today allows diverse antenna sites to have direct RF connectivity to a single data center, without installation of all the based band data center equipment at each antenna site. This provides cost-savings, and operational ease compared to the installation of complete antenna or baseband traffic site redundancy configurations. Ka-band networks can achieve higher resiliency using RF-over-fiber antenna diversity. If scaled across multiple gateway sites, this kind of solution can increase overall usable satellite network capacity by allowing traffic be routed to less satellite resource-hungry sites during rain. This will help Ka-band systems maximize their competitiveness and ability to address a broader range of customer needs.
