Device to device communication using software defined radios on 4G cellular networks
Abstract
With the increasing number of mobile devices with multiple service requirements,
the Third Generation Partnership project (3GPP), has advanced the network
infrastructure and level service in terms of the speeds, bandwidth, security and
delays in communication. This has caused the rapid evolution through different
cellular communication generations.
Currently advancement is towards 5G and 6G which is ultra reliable and low
latency network, supports massive machine time communication and enhanced
mobile broadband. With advancement tending to 5G, the number of devices
supporting data intensive applications such as real time gaming and Machine Type
Communication has increased. These applications cause data traffic over the base
stations with increase in the delay and reduction in data rates. Device to Device
communication allows devices in close proximity to exchange data traffic without
traversing the base station.
Therefore, it is a key solution to ensure a better spectral efficiency, higher data
rates and low latency. However 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 Open-Source software and Software Defined Radios.
