LoRa network testbed performance evaluation in UiTM Perlis

Wireless networks are crucial in today's connected world, where IoT devices are being implemented in many environments such as smart homes, smart offices, and smart cities. LoRa (Long Range) are designed for IoT communication where devices enable connection between remote end nodes and LPWAN for analytic applications. LoRa Technology offers a promising alternative, providing low-power with long-range wireless data transmission. For a LoRa Network to be deployed, a performance LoRa analysis needs to be executed in the campus in order to measure received signal strength (RSS) and signal-to­noise ratio (SNR) for its usefulness. The research objectives are to set up the LoRa testbed in both indoor and outdoor environments and analyze the network performance. The LoRa testbed consists of a gateway and a few nodes that were deployed around the campus. The results for the indoor environment on three floors show higher RSS on the first floor, indicating acceptable signal coverage with the range of SF7 to SF12, whereas in outdoor only 15% coverage compared to the overall buildings except plantation area in UiTM Perlis.
