Analyst firm expects automotive to remain the biggest single cellular IoT market.

Global cellular IoT connections will increase to 2.4 billion in 2025, up from 520 million in 2016.

This is according to Strategy Analytics, which on Tuesday predicted that by then, the automotive, utilities and security markets will account for more than 46% of cellular IoT connections.

The automotive sector will remain the single largest consumer of cellular IoT connections, growing its market share by 2025, the analyst firm said.

"With the industry focusing on the path to 5G and low power 3GPP offerings, such as LTE Cat M1 and NB-IoT, coupled with a variety of established connectivity platforms, there are lots of choices for cellular connectivity in the IoT and the outlook has never been brighter," said Andrew Brown, executive director of enterprise and IoT research at Strategy Analytics, in a research note.

The predictions are broadly in line with those of Machina Research, which last year predicted that cellular IoT connections would reach 2.2 billion by 2025, up from 334 million at the end of 2015. It expects the automotive industry to account for 45% of those connections.

Strategy Analytics said on Tuesday that Asia Pacific will continue to be the largest single region for cellular IoT connections during the forecast period, accounting for 1 billion of them.

The world’s top three cellular IoT regions – Asia Pacific, North America, and Western Europe, will together account for 75% of global connections in 2025, the company predicted.
