Real-Time Communications Student Presentations - Fall 2016

Real-Time Communications students in professor Carol Davids class presented their final projects and provided demonstrations and poster sessions about their Real-Time Communications class projects. 


  • Indoor Location for NG911 calls using iBeacons 
    • The students described and demonstrated their system for providing the indoor location of a 9-1-1 caller based on the location of BlueTooth beacons, a Location Server and Database, and an Android application, all of their own design.
    • Since their last presentation in April the student team has begun research exploring the impact on the accuracy of the location provided when the distribution pattern of the iBeacons is varied and when the algorithm used to locate the caller is changed. They will report on their current results and plans for continued research.
  • SIP for Mobile Networks: The students continued development of a 2G network that uses Software Defined Radio (SDR) technology and a SIP server to replace the base transceiver station (BTS). This semester they are routing calls that originate on this network to the NG9-1-1 test bed in the RTC Lab.
  • WebRTC-based PSAP for Emergency Communications: The students described and demonstrated the current state of our WebRTC-based Public Safety Answering Point (PSAP). This semester the team has added to the PSAP display features, including a map feature. It has also begun to build the SIP-to-WebRTC interface that will allow standards-based SIP emergency calls to flow through to a web-based PSAP.
