Over the air firmware update is a core requirement for large scale IoT deployments especially when LoRaWAN devices are distributed in remote and inaccessible environments Since LoRaWAN provides low data rate strict payload limitation and downlink constraints FUOTA becomes a technical challenge This article explains the engineering difficulties behind LoRaWAN FUOTA and presents Manthink’s mature solution based on MPOS OS the EB computational framework and multi bin fragmented upgrade technology suitable for massive distributed IoT systems
1 What Is FUOTA?
FUOTA allows remote firmware upgrades for thousands of devices without physical access. In LoRaWAN systems where bandwidth is low and packets must be fragmented FUOTA determines whether a deployment can be reliably maintained over years.
2 Challenges of Implementing FUOTA on LoRaWAN
2.1 Large Firmware Size and Unstable Wireless Links
Table 1 Impact of Firmware Size on FUOTA Performance
2.2 Fragmentation, Reassembly and Synchronization Complexity
