A low energy computer infrastructure for radio VOIP supported communication and SDR APRS in education and disaster relief situations

A low energy computer infrastructure for radio VOIP supported communication and SDR APRS in education and disaster relief situations In long duration emergency and large scale disaster situations, information on asset position, information of current and information history of weather conditions, and communication are crucial for every rescue operation. Picture and voice are crucial so that affected population can make important decisions and take actions. Available technology offers affordable (low cost) and robust infrastructure solutions in disaster relief situations supported by radio amateur communication. In this paper we presented three types of services for which same hardware in essence can be used. First service is forGPS location mapping, second one is for VOIP communication, and third one is to provide real time video capturing. GPS location mapping was performed by using APRS-IS SDR, VOIP communication is performed via radio-svxlink-Internet using Echolink (svxlink which is linux compatible version) software, and for video capturing was used using Motion software. All above stated services is possible to install on low energy microcomputer such as Raspberry Pi which can be powered with 5 V battery or with mobile phone power adapter.
