An early-warning service for emerging communication problems in security and safety applications

Experience has shown that unpredictable disruption of communications during emergency operations can have severe consequences both for personal safety and for the ability to conduct a successful operation. An early-warning service for emerging communication disruption due to both unintentional interference and jamming, would therefore be a significant contribution for increased safety and security in such operations. We propose a solution for such an early-warning service both on the terminal and on higher system level. The solution is based on historical recorded data of both local and global information such as signal-to-interference ratio, interference classification, and position. We show by an example that with this service implemented, the operator will have increased time to take actions before a disruption occurs on a specific terminal.
