Abstract

Electricity distributors currently face heavily reduced operating and capital investment budgets in an effort to reduce household power bills. With the predicated high growth rate of the Internet of Things the following project has researched the possibility of sing this wireless technology for use in an electrical distribution network. The low cost and long range ability of LoRaWAN system provides numerous opportunities to provide distributors and customer’s information about power usage as well as provide access to once un‐financially viable communications.

The project researches the LoRaWAN specification and where the technology currently sits in Australia. It will define possible uses for the technology in the electrical distribution industry and also examine the types of devices to establish a LoRaWAN network. Most of the objects and devices that will connect to the LoRaWAN network will only require low data rates/response times and small packet data.

After conducting a literature review which details the LoRaWAN specification, LoRa modulation techniques and system architecture the project methodology then identified possible devices to use for the design and implementation of a LoRaWAN network. Theoretical analysis of coverage plots and expected range was completed which was then used for testing the live system.

Lab testing of the LoRaWAN system was completed together with line of sight drive testing using various data rates in urban and rural environments. Data rates were chosen from some typical devices that may be used in the network such as smart meters. The system functioned in line of sight applications as specified with objects having a range of 20km. Lastly limitations and recommendations have been made for the system to be used in a real life application.
