Profiling reported SNR from LoRa sensors deployed in Bristol

In the Winter 2021 issue of the SWAN newsletter, we shared an article about a precursor project to SWAN’s work on LoRa, which was funded by the National Security Technology & Innovation Exchange (NSTIx). Building on the LoRa gateway deployments and sensors provided through this pipe-cleaning project, an initial measurement campaign has been conducted to … Read more

Developing methods of RF fingerprinting to improve the resilience of LoRaWAN networks

The ever-increasing use of low-power wireless sensor technology for sensing and monitoring applications, including use cases within critical infrastructure, identifies a need to make this technology robust against cyber-attacks. Within SWAN, we have adopted LoRaWAN, a proprietary low-power wide area technology developed for the Internet of Things (IoT), as a candidate technology for detailed evaluation … Read more

SWAN’s Initial RF Penetration Test-Bed

SWAN’s postdoctoral researchers, with valuable input from our industrial partners, have built their first Radio Frequency (RF) penetration test-bed (pen-test facility) using LoRa as the candidate air interface technology. A pair of SODAQ explorer evaluation modules populated with the RN2483 LoRaWAN transceiver and stack have been deployed in a pair of Tescom TC-5916A RF screened … Read more
