eBay has urged the government and Ofcom to get the new generation of 4G mobile broadband rolled-out by the end of 2013.
The internet auction giant has submitted a "Mobile Manifesto" to ministers setting out what industry and policymakers need to do to support the country's "burgeoning" mobile economy.
Ofcom was recently forced to peg back the auction of 4G mobile broadband from early next year to between October and December 2012.
The delay was fuelled by legal complaints and commercial disputes between broadband operators, according to ISPreview.co.uk. However, the regulator still hopes the first commercial services will surface in late 2013.
eBay claims in its report that the UK's digital communications industry, including mobile operations from retailers, network providers and developers, is worth over £50 billion to the UK economy and directly employs 531,000 workers in the UK.
Research commissioned by the website found that consumers are being held back from spending because the speed at which they can complete everyday functions like browsing and shopping on mobile devices is inadequate.
Nearly half (45 per cent) of the 2,000 consumers polled said they were dissatisfied with the speed at which they can download mobile data.
eBay is calling on Ofcom to prioritise improvements to mobile broadband coverage on key infrastructure routes such as railways and roads as 36 per cent of consumers already shop on their devices whilst travelling.
Miriam Lahage, Vice President of Global Fashion at eBay, said: "The mobile economy is proving resilient as people increasingly see owning and using a mobile as an essential expense, despite cutting back in other areas.
"As tablet ownership increases there will be even greater potential rewards for companies investing in mobile, and this is particularly true for retailers."
