Enabling Firmware Updates Over LPWANs
Low-power wide-area networks (LPWANs) – such as LoRa and Sigfox - are considered one of the most suitable connectivity technologies for emerging IoT devices. LPWAN networks combine kilometres of range with years of battery life, and operate in unlicensed spectrum. However, LPWAN networks are very constrained, providing data rates measured in bytes per second, and are subject to duty cycle limitations on many continents. For example, in Europe there is a 1% duty cycle on most bands. In addition, LPWANs operating in the ISM band (open spectrum) can suffer from low Quality of Service, with many other devices and protocols using the same signal spectrum. With these constraints firmware updates - a must if you do large scale long-term IoT deployments - seem impossible. On top of that, firmware updates are bigger than just a network spec. It involves cryptographic verification of firmware, smart gateway planning and shaping your traffic in a way that does not interfere with the rest of your network. This session will explore the challenges of rolling out a firmware update service over LoRaWAN, including a secure reference implementation for both network and device, using an open source license.
