Your primary task will be practically oriented research based on experimenting with software defined radios, mostly USRP from Ettus Research. You will be part of a small team experimenting with mobile networks (GSM, UMTS, LTE, 5G) using open-source stacks and exploring expected (or unexpected) behaviour of both mobile networks and phones. Most experiments are on Layer 2 and Layer 3 of the mobile network communication protocols (authentication, call establishment, handovers, etc.).
