Many IoT devices are expected to use cellular networks and operators expect to get lots money on the process (Beecham Research expects US$8.9 billion in connectivity revenues for mobile operators by 2020). The threads to that are that huge number of IoT devices can at worst case seriously overload the limited cellular network resources. Cellular Group Rolls IoT Guidelines article tells that trade group GSMA released version 1.0 of its “IoT Device Connection Efficiency Guidelines,” a 70-page document outlining best-practices for chips, systems, and apps riding the cellular network. It is worth to check document if you are into IoT. The GSMA is developing a set of acceptance tests for IoT devices and applications to ensure best-practices are being followed (expected to be ready early next year).
Cellular Group Rolls IoT Guidelines article also tells that embedded SIM specification for remote provisioning of machine-to-machine (M2M) devices is getting support from many operators and module makers. This eUICC spec is expected to accelerate IoT growth (currently fragmented market, the number of cellular M2M connections could rise from 478 million today to 639 million in 2020).
