Connecting the UK's rural areas with broadband poses a logistical challenge for mobile broadband providers as well as fixed-line operators.
That is according to Richard Warmsley, head of internet and entertainment at T-Mobile, who was speaking to PC Pro in the wake of Lord Carter's Digital Britain report.
In his recent publication, the communications minister set out plans to cover the whole of Britain with broadband access offering speeds of up to 2Mb.
However, while many have highlighted mobile broadband as a possible solution to the problem of connecting remote areas, Mr Warmsley has suggested that it is not that straightforward.
He said: "The cost of putting mobile-broadband access in relatively low population places is always going to be a challenge. The economics are always going to be a factor."
"The next stage [of Digital Britain] is to look at the practicalities," he added.
While some Brits are still without access to broadband internet, BT recently announced the areas which will benefit from the first stage of its £1.5 billion super-fast broadband roll-out, including several cities in Scotland, parts of London and districts in West Yorkshire.
