Performance Evaluation of LoRaWAN on Campus Environment

LoRaWAN is emerging as one of promising wireless technologies for long range IoT communications. At its early stage, its technical specification promises long, reliable communications in ranges up to tens of km (in a rural area). However, its performance of connectivity has not been proved in a real world environment yet. To answer a question of Does it work well in the real setup?, this paper evaluates connectivity performance of LoRaWAN communication technology on a real world campus environment. To this end, we have built a testbed system on our campus and ran experiments measuring RSSI, SNR, and PDR. By analyzing experimental results, we evaluate data delivery performance of LoRaWAN technology.
