Industrial IoT faces big challenges

Future cellular Internet of Things (IoT) networks are going to be expected to deliver much lower latency and significantly higher reliability. Getting to that point, however, must be a step-by-step approach, said a telco equipment executive at Mobile World Congress Americas earlier this month.

“Doing one at a time is not so difficult, but doing both at the same time is a challenge,” said Jawad Manssour, head of Networks Portfolio Management at Product Area Networks with equipment maker Ericsson, during a presentation at the conference.

Ericsson is one of the world’s big three principal base station and cellular equipment vendors, along with Huawei and Nokia. Mobile network providers Sprint and Ericsson recently announced that they are building a distributed virtualized core IoT network and an IoT operating system.

Manssour said one needs to look at IoT evolution in four distinct genres — Massive IoT, High-Performance IoT, Critical IoT, and Industrial IoT — to fully appreciate the challenges of IoT overall as use ramps up. Currently 700 million connections are on cellular technology IoT, but that is expected to scale to 3.5 billion by 2023, he said.
