The number of people accessing both fixed-line and mobile broadband will rise to 1.4 billion by 2015, a new report has claimed.
Analyst firm Ovum expects the two services to converge over the coming years as internet usage continues to increase.
The company said these dual access subscribers will mainly be in the developed markets of North America, Western Europe and Asia Pacific, where 84 per cent will have dual access.
Charlie Davies, Ovum Analyst and report co-author, said: "This convergence of services will see operators growing the revenues they generate from users by offering service bundles."
However, he noted that dual access use will not only be restricted to the mature markets of the developed world.
"Rapidly growing urban areas in the emerging markets where there is a larger proportion of high-value customers will also see growth in this area," he commented.
In a separate Ovum report, the analyst recently predicted that one million people will use mobile broadband as their main form of internet access by 2015.
