Revenues from IoT connectivity will increase sharply by 10% per year to fill some of the void left by falling voice and data revenues, accounting for 7% of operator enterprise revenue by 2022.
That's the finding of telecoms research and consulting firm Analysys Mason, which says the worldwide market for telecoms business services will grow from $411bn in 2017 to $415bn in 2022.
"Operators need to look at the opportunity to upsell new services," said Catherine Hammond, Senior Research analyst at Analysys Mason.
"When you're hitting the wall in terms of revenues, it's about bundling, upselling and retaining customers by serving them with a bigger, better package.
"By providing cloud and business services to all sizes of enterprise, operators will be able to sustain their revenue and make themselves increasingly valuable to their customers."
