Connected devices such as smart light bulbs, refrigerators and TVs are all bound by Wi-Fi networks. But that might not be the case for much longer.
Arm, a processor design company, is unveiling a new software stack, called Kigen, that would allow SIM cards to be integrated into internet-of-things devices. That is, your smart objects could connect to the internet more like a phone, rather than being dependent on Wi-Fi. And that could be big business: The company is looking ahead to a trillion connected devices by 2035, though the cellular IoT market would be only a portion of that.
