Implementing device to device Communication using software defined radios on 4G Cellular systems

Abstract

With the development of the Third Generation Partnership Project (3GPP), cellular communication has reached 4G standard supporting increased speeds and bandwidth. With the advancement tending to 5G, a large number of devices have been on the rise particularly short range devices supporting data intensive applications such as Machine Type Communication, Vehicle to Vehicle Communication, real time gaming. These applications cause traffic over the base station. As a result, there has been delay in response to user requests. Device to Device (D2D) communication is a key solution to ensure a better spectral efficiency in the cellular spectrum. There have been no working test beds. This report explains the details of the steps taken to establish a test bed to implement D2D using srsRAN Open Source software and Software Defined Radios. The performance of D2D in comparison with cellular communication is discussed in this project.
