Increasing Throughput and Efficiency of LoRaWAN Class A

Authors:

Keywords: LoRa, LoRaWAN, TDMA, Burst

Abstract:
The number of Internet of Things (IoT) devices is expected to increase significantly in the next few years due to the availability of low cost IoT hardware and new application scenarios. As a result, many more wireless IoT devices will share the unlicensed frequency bands. Coordinated channel access is required to increase the efficiency of the frequency spectrum usage. In this paper, we propose two extensions to Long Range Wide Area Network (LoRaWAN) Class A, the TDMA and Burst scheme, in order to increase the channel utilization and system throughput. Our calculations show that the proposed schemes can provide more than 60% throughput compared to 18% provided by the pure ALOHA scheme used in the current specifications of LoRaWAN. We verify the feasibility of the schemes with an implementation and measurements on eight LoRaWAN end-devices and one gateway.
