Sub-Gigahertz Inter-Technology Interference. How Harmful is it for LoRa?
Sub-one GHz technologies are getting utilized for different applications in home automation and smart cities, due to their long coverage range and support for large number of end devices. Due to different technologies used by different applications and device vendors, the impact of each technology on each other needs to be assessed in environments where multiple technology are used and most of the time they are coexisting with each other. In this paper, we show an inter-technology interference measurement setup for LoRa, Sigfox, Z-Wave and IO Home Control. In the setup, the packet transmissions are controllable in time and frequency, that makes it possible to test and evaluate various interference scenarios. From the designed and implemented setup, we evaluate the impact of the sub-GHz technologies (Sigfox, Z-wave, and IO Home Control) on LoRa. The results show that there is a significant loss (up to 20%) and a relatively lower loss (up to 12–15%) under Sigfox and Z-Wave or IO Home Control, respectively, when the interferer starts during the preamble and header time. Losses are practically zero if the interferer starts during the payload time.
