Device to Device Communication on Software Defined Radio for 4G Cellular Network

Abstract

4G and 5G networks aim to provide new types of services such as vehicle to vehicle and machine to machine communication, industrial automation, gaming and so on. These services require high quality of services such as high capacity, ultra-reliability and low latencies. D2D communication presents a potential solution by assuring connectivity of a larger number of devices and lower latencies. This work investigated D2D communication on software defined radios for 4G cellular networks. The SDR platform used was blade SDR. The Core Network that is Home Subscriber Server (HSS), Mobility Management Entity (MME) and Serving-Packet Data Network (PDN) Gateway (SPGW) and OAI eNodeB are installed on the same laptop. A bladeRFx40 SDR with two antennas one for transmission and reception is attached to the laptop to complete the eNodeB. tests were conducted using a software-defined radio (SDR) platform. An SDR based system was selected to enable a low cost and highly flexible iterative approach to development while still providing the accuracy of real-world measurement. D2D functionality was added to the chosen SDR system with the essential parts of Long Term Evolution Release 8 implemented. iv
