Abstract —A multi-hop approach can extend network coverage, including connectivity to difficult-to-access areas. This paper discusses the implementation and evaluation of the two-hop real-time LoRa (Two-hop RT-LoRa) protocol previously proposed to be used for industrial monitoring and control applications. The protocol was implemented on LoRa devices to support a multi-hop LoRa network that consists of one LoRa gateway and 40 end devices. It is shown with various campus deployment scenarios that the protocol improves reliability in data transmission significantly.
