In today’s increasingly digital-first world, emerging 5G technology and its faster speeds, lower latency, and expanded connectivity promises to become an essential component in how we live, work, and play.

“5G is set to be available in almost every part of the world in the next two years, and many people, especially IT professionals, have high expectations regarding its performance. Individuals are also eager to learn about its capabilities and how it differs from previous networks,” wrote Devin Partida in TechRepublic. “Many service providers are already rolling out 5G across countries like the U.S., U.K., and China.”

A study by Juniper Research published last year predicted that 5G service revenue would reach $315 billion globally this year, rising from $195 billion in 2022 to become 35 percent of operators' total revenue.

“This represents growth of over 60 percent in a single year,” said the study authors. “The research predicts this increase in revenue will be driven by the accelerating migration of cellular subscriptions to 5G networks; owing to operator strategies that minimize or remove any premium over existing 4G subscription offerings.”

The study suggests this is just the start of a 5G network wave with over 80 percent of global operator-billed revenue to be attributable to 5G connections by 2027.
