Today, the deployment of LoRa gateway in Indonesia uses only traditional methods by predicting the coverage and capacity without using formulas related to LoRa gateway performance or considering area type (urban, suburban or rural). This paper conducts the study and research for coverage and capacity analysis of LoRa Gateway to cover all sensor device demands. The formula is calculated to save more resources and optimize the performance of the LoRa gateway covering all demands needed for Smart Gas Meter devices in Urban areas. The location taken as a model is Jakarta City. In order to obtain the number of gateways to cover all smart gas meter demands, this paper uses the Okumura-Hata formula to obtain coverage prediction for each gateway. It uses time on air and interval concepts to determine capacity per interval times. The calculation result is about 4 LoRa gateways need to be deployed, and the interval of transmission data is about once per 35 minutes to cover all Smart Gas Meter devices in Jakarta.
