The internet of things (IoT) subject became widespread during the last decade while 25 billion connected devices will dominate the life by 2030 due to statistical expectation reports. In smart cities, sensors mostly use wireless communication facilities involving huge energy consumption risk. Long range wide area network technology is one of the main solutions inside the low power consumption wide technologies era that are called LoRa and LoRaWAN. In this case study, there are totally 232 water-meters in the research area. Water-meters are deployed in a three-blocksapartment in city of Bursa. We selected one water-meter from every floor. Totally 56 LoRaWAN supporting water-meters selected for performance analysis. Network design and

performance analysis are studied focusing on received signal strength indicator (RSSI), signal-to-noise ratio (SNR), spreading factor (SF) and message transmission number by debugging the

LoRa gateway logs. Best RSSI values are created by the Block B water-meters which are nearest end-devices (EDs) to gateways (GWs) while Block A and C values are already better than the theoretical limits. Also, in comparison to SNR values, Block B has better results. In conclusion, it is detected that Block A uses SF12, Block B uses SF7 and Block C uses SF12 values mostly.
