Ka-Band Diversity

State-of-the art satellite communication systems at the highest data rates are operated on the Ka-Band. As transmission quality on Ka-Band frequencies is heavily dependent on weather conditions, suitable system configurations need to be carefully planned and chosen. Ka-Band Site Diversity configurations relying on DWDM RF-over-Fiber transmission systems and redundancy switching units represent best-suited solutions and ensure maximum system reliability and system availability.

RF Signal Management for an IPTV head-end

The customer is looking for a RF signal management solution for a new IPTV head-end. In order to reach maximum availability the IPTV head-end will receive the satellite signals via two Diversity Antenna Sites (~80km distance between the sites). The RF signal management solution needs to ensure reliable transmission, selection, switching and distribution of the antenna signals.
