Development of UT user terminal to UT Voice, Image, Video and Data Communication APP Android or iOS
Problem Statement Title Development of UT (user terminal) to UT Voice, Image, Video and Data Communication APP (Android or iOS) using Bluetooth 2.0 or above wireless interface and custom protocol Description Two-way voice, video and data Communication between two UTs through BLE (Bluetooth) needs to be addressed using Custom Protocol (with minimum signalling overheads). The APP should establish a BLE connection among peer UT as part of initialization and thereafter carry out full-duplex communication using a custom protocol format viz- Header Payload. The size of header should not be more than 1/8th of Payload size and the delay/latency in voice or data communication should be less than 200ms. The header should contain a Unique word with advanced features so as to facilitate synchronization with minimal false detection probability. It is expected that the application uses a standard ITU vocoder and maintains a constant transfer rate between UT’s. This is an essential feature for the end application. UI- The UI should have options for voice, Image, Video or data transfer. It is also expected to have a built-in dialer, contact list wherein each UT is assigned a unique ID/Contact ID through which communication could be established. Note- The custom protocol and sample data will be made available after proposal evaluation.
