Portable IP-based communication system using Raspberry Pi as exchange

Abstract

The importance of communications and information trigger the development of communication network technology in order to be easy, cheap, efficient and has wide coverage area. This research designs an easy, cheap, and efficient IP-based communication system for voice and video. The aim of this research is to know the performance of telecommunication system for voice and video communication in terms of throughput, jitter, delay, and packet loss according to ITU-G.114 standard. This research also optimizes coverage area by adding 8 dBi omni-directional antenna. The arrangement of communication system is done by Raspberry Pi as server using ArteriskFreePBX software. Linphone and Bria as softphone in client devices. Then configure the SIP account to make voice and video communication. The test scenarios are communication between laptops, communication from laptop to smartphone, and communication between smartphones. The results obtained that the farthest distance from the wireless adapter between the server and the clients is 100 m. The testing network performance parameters based on ITU-G.114 standard, the farthest distance that can communicate between Smartphones is at 140 m for audio and 80 m for video, Laptop to Smartphone at a distance of 180 m for audio, 80 m for video. Communication between Laptop for video communication at a distance of 120 m and for audio can communicate well up to 200 m distance. This research is expected to be used as reference and alternative a cheap and portable telecommunication device.
