Özet:

The low power requirements of LPWAN technologies, long-range transmission capabilities, scalability, broad-space capabilities and other parameters are assessed, and their use in IoT applications increases everyday. In this study, the performance of LoRa and NB-IoT technologies is assessed on a site in the Eyüpsultan district of Istanbul. The LoRa tests are performed on the gas measurements in the corridors, while the NB-IoT tests are observed within the measurements behind the metal cover. In the LoRa tests, RSSI and SF are recorded; in NB-IoT, RSSI values are recorded. The analyses were made on 14 for LoRa; 16 for NB-IoT packages. The results showed that the 30 packages sent reached the base stations without a loss, while the signal quality was not in the ideal range at certain points. In this case, it is expected that the package will be lost. However, it should also be pointed out the need to perform more tests on packages for a better observation.

Considering the parameters such as low power requirements, long-range transmission capabilities, scalability, and inclusiveness of LPWAN technologies, their use in IoT applications is increasing. In this study, the performance of LoRa and NB-IoT on a site in Eyupsultan district of Istanbul is evaluated. While LoRa tests are carried out on the gas meters in the corridors; In the NB-IoT tests, observations were made inside the meter shafts behind the metal cover. RSSI and SF in LoRa; In NB-IoT, RSSI values are recorded. 14 for analyzes LoRa; Made on 16 packages for NB-IoT. While the results showed that the 30 packets sent reached the base stations, it was observed that the signal quality was not ideal at certain points. It is predicted that the packages will be lost when installed under these conditions. However, it should be noted that tests on more packages are necessary for a better observation.
