'A Review of LoRaWAN'
A brief summary of the current status of LoRaWAN as a communications technology. Starting with some basics of the LoRa modulation technique and deeper dive into the LoRaWAN specification produced by the LoRa Alliance. Then onto some examples of products on the market and how they enable users to quickly deploy their own LoRaWAN solution. Finally, a quick look at the commercially available network solutions including satellite based solutions.

'Rogue Sensor Identification for LoRaWAN deployments'
With the ever-increasing use of low-cost wireless IoT technology for telemetry applications, including use cases within critical infrastructure, ensuring the ongoing security and resilience of these technologies is of paramount importance. However, as with many of the wireless networks that underpin modern life, these technologies rely on radio frequency (RF) interfaces which can be vulnerable to cyber-attacks or other failures. The detection and mitigation of potential RF cyber intrusions forms one of the research priorities of the UKRI Prosperity Partnership in Secure Wireless Agile Networks (SWAN).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 given the increasing prevalence within remote telemetry applications. In this presentation, a novel unsupervised machine learning (ML) algorithm is presented for the expeditious RF fingerprinting of LoRa modulated chirps, as rogue device identification based on received signal strength indicator (RSSI) alone is unlikely to yield a robust means for sensor authentication within critical infrastructure deployments. Specifically, an unsupervised ML algorithm is used to rapidly train an artificial neural network (ANN) matrix creating self-organizing maps (SOMs) for each authentic transmitter and a potential rogue node. The SOMs are then used to train a general classifier which will be shown to reliably profile each transmitter as friend or foe.

Daniel Clarke, Stakeholder & Partnerships Manager, Connecting Cambridgeshire
'Local Authorities and LoRa WAN – supporting communities, business and service delivery'
Local Authorities are adopting LoRa WAN to gather better information to support service delivery, their local economies and to support local communities. Cambridgeshire will talk about why they are building a LoRa network, how It is being used and some of the deployment issues they have faced when rolling out a network.

‘LoRaWAN - Where next? 'Space, the Final Frontier'
How far can LoRaWAN go? The new LoRa LR-FHSS modulation scheme, adopted into the latest revision of LoRaWAN increases range and spectral density, allowing better in-building penetration. In parallel, the Cubesat revolution allows deployment of gateways and relays in low earth orbit, extending coverage to areas where none exists. This presentation covers the rise of infrastructure-less low power communications, the technology behind them and how hybrid terrestrial and satellite operation avoids roll-out-and-hope network planning.
