Top 10: IoT Connectivity Platforms

The telecommunications sector is undergoing a profound shift. Once defined primarily by its role in providing connectivity, it is now positioned to become a central orchestrator of value in the rapidly expanding Internet of Things (IoT) ecosystem. No longer is it sufficient to connect devices; the challenge now lies in managing, securing and harnessing intelligence from billions of endpoints. With the global IoT platform market forecasted to reach US$35.1 billion by 2032, growing at a 13.2% annual rate, the scale of the opportunity is clear.

For Communications Service Providers (CSPs) and Mobile Network Operators (MNOs), the task is to rise above the commoditised role of connectivity and secure a stronger presence in the value chain. Telcos must determine whether to embrace platforms that empower them as digital service orchestrators or risk being reduced to low-margin “dumb pipes” in a market increasingly shaped by hyperscale cloud providers.

This week, Telco Magazine delves into the top 10 IoT connectivity providers.
