Abstract
In this paper we share our experience with remote software updates for NB-IoT devices. The experience was collected over the years, when managing a fleet of tens of thousands of NB-IoT wireless sensors deployed worldwide by our customers. The paper discusses the main concerns that must be taken into account when designing the remote software over the air (SOTA) update mechanism, describes the remote update algorithm developed and used by us and presents the achieved experimental results based on remote software update of 5 000 NB-IoT sensors deployed in 10 European countries.
