Broadband Critical Communication System

By Prof. Prasanna Chaporkar


Mission Critical Communication was traditionally done using narrowband technology and devices that allowed only for audio communication among the first responders. The technology and devices used for this kind of communication, both, are now reaching their end of life. Organizations across the world are now involved in a paradigm shift to adopt the broadband technology for doing Mission Critical Communication and see if it can provide them better situational awareness as well as overcome the limitations of the communication done using narrowband technology. This paradigm shift is being fuelled by the Public Safety LTE (PS-LTE) standard by 3GPP consortium which lays down the framework for doing Mission Critical Communication using audio, video and messages (data). This presentation outlines the work done under the Broadband Critical Communication System project at NCETIS, IIT Bombay in understanding and implementing parts of the PS-LTE standard to build a prototype showcasing the Push-to-Talk communication on an Android Smartphone as the end-user device.
