Connecting remote sensor sites where there is no or poor communications infrastructure is a real challenge. There is a clear need to maintain quality data from sensors and some of these feeds can be bandwidth hungry, particularly video.
If sites are within a reasonable distance, then microwave or other communication methods can be utilized, otherwise satellite communications such as VSAT can be implimented.
SSR surveillance systems use various techniques to reduce the bandwidth while maintaining the quality of data required to effectively monitor the surveillance area.
Remote sites include vessels or mobile vehicles.
