Propagation measurements for a LoRa network in an urban environment

LoRa is a relatively new proprietary communication technology that allows long-range communication distances while consuming very little power. It utilizes license-free Industrial, Scientific and Medical ISM frequency bands to exchange information at low data rates. LoRa is favourable when looking for limited exchange of data and low-cost devices and infrastructure. This work presents some preliminary propagation measurements in a typical urban environment by using prototype transmitters and receivers working in a private network. Results highlight that LoRa can be used as a communication technology for different ad-hoc networks deployed in an urban area.
