Automatic Radio Selection for Data Transfer in Device to Device

Abstract

Over the years, as technology evolves in telecommunication, the choice of the kind of radio to be use for data transfer in a multi radio system at a particular time still remains a challenge especially in D2D communications. This is evident in popular user equipment’s such as phones where multiple radio systems such as Bluetooth, WiFi and GSM are present. Despite all these radios in place, the selection of these radios has always been done manually by users which often time, is time wasting before instantaneous data transfer and sometimes fail due to unsimilar radio selection which leads to unsimilar channel operation of the two devices. To mitigate this and to have a smarter system, there is need for D2D to be able to automatically select radio for data tra nsfer based on certain yardstick. One of such yardsticks remains area of coverage as different have different rage of coverage area.to this end, this research presents AUTOMATIC RADIO SELECTION FOR DATA TRANSFER FOR D2D DEVICE. This was used via the use of GPS module, Bluetooth device, Lora module and an Arduino Nano. At the end of the research, the radio selection was possible but with error in distance measurement.
