Abstract [en]

A comparative study between the techniques Bluetooth Low Energy and Bluetooth Classic has been performed in cooperation with Saab AB with the purpose to determine which technique is best suited for transmission of data between an Android unit and an embedded system. The parameters that has been analyzed are throughput, energy efficiency and susceptibility. The study has been performed in accordance with the method Design Science Research and has therefore produced an artefact in the form of a system that has been evaluated in an experiment where performance parameters have been measured and analyzed.

The results show that BLE is more robust in environments with a high level of noise and can handle lower SNR levels than BR/EDR; 3 dB vs 7,5 dB. If enough transfer speed is reached, BLE would also give the best energy efficiency and if the specified maximum throughput is reached, BLE would, according to this study, have more than double the energy efficiency as BR/EDR. BLE is, according to most measures, preferable from Bluetooth version 5 and is future-proof but BR/EDR still provides the highest throughput.
