Command and control communication for search and rescue (SAR) operations using smart phones for audio, video and monitoring functions

This paper proposes a combination of network frequencies as the supporting medium for communication within a small Search and Rescue (SAR) team to ensure stable communication, and thus command and control, in particular in a forest environment. The proposal is to implement a combination of 869 MHz and 2.4 GHz, which will support the use of smart phones for the SAR team members for audio/oral, visual and data communication as well as other facilities, the most important being location monitoring. The proposal also includes the positioning of the (mobile) base station for uninterrupted coverage
