Despite the growing volume of Long Range (LoRa) wide area networks (WAN) devices, there is limited research on the antenna's influence on a node's connectivity. In this paper, the channel gain of an 868 MHz LoRa-Wan node in an urban environment is used to evaluate the performance of different antennas, as well as evaluate motion, elevation, and shadowing effects on the nodes connectivity.

Abstract

Despite the growing volume of Long Range (LoRa) wide area networks (WAN) devices, there is limited research on the antenna's influence on a node's connectivity. In this paper, the channel gain of an 868 MHz LoRa-Wan node in an urban environment is used to evaluate the performance of different antennas, as well as evaluate motion, elevation, and shadowing effects on the nodes connectivity. A dual-transmitter node with two tightly-coupled antennas is utilized to characterize the channel gain between the antenna-under-test, and multiple indoor and outdoor gateways over 1 km away, through the relative signal strength (RSS). It is demonstrated that using a broadband UWB-inspired monopole implemented on an inexpensive cardboard substrate, the channel gain can be improved over commercially available whip antennas.
