By 2025, GSMA Intelligence forecasts the total number of IoT connections will grow to 25.2 billion.
Breaking these numbers down, Ericsson projects 5.2 billion cellular IoT connections also by 2025. This means that, by the mid-2020s, cellular IoT connections are expected to number more than 60% of mobile handset subscriptions and growing faster.
The largest proportion of these IoT connections are expected to be low-cost devices that are small in size, have limited processing power and storage, are battery driven and expected to run for 10 or more years.
These devices must remain connected to deliver sensor data and act upon commands from remote locations, and they must do this securely. Secure identities are required to identify these devices and their data, as well as protect them from misuse by remote attacks.
The sort of use cases this covers are sensors, trackers, wearables and other low-cost devices that will increasingly form the backbone of the IoT – a myriad of data sources providing real time information on our world and how we live.
