Reliability of SATCOM transmission for PPDR usage

Satellite transmission based on IP may play important role for communication between event site and PPDR centers during large planned scenarios and disaster/unplanned ones. Geostationary SATCOM links that can be installed ad-hoc in any location present reliable and efficient way to transmit IP data even for voice communication based on VoIP. Using different mechanisms that handle multi connections the reliability of data exchange among PPDR agencies can be improved. The efficiency of satellite communication is reported by tests done for TCP and UDP transmission in Ka band.
