The product is a Peer-to-peer video telephony system implemented using GNU Radio running on a PC and USRP as RF frontend. The product will make use of a relaying technique to improve the performance of the link. Overall, the product is divided into four sub-systems, which are Peer Transmitter, Peer Receiver, Relay and GUI (Graphical User Interface). The radio architecture for Peer Transmitter, Peer Receiver and Relay are similar. The GUI running on each peer and the GNU radio on each radio will be implemented using Python.
