Three has expressed concerns that it may run out of wireless spectrum capacity by the end of next year.
The broadband provider believes its 3G network could reach saturation point, which could prevent the firm from maximising its growth potential.
As such, Three is eager for the government to press ahead with the 4G spectrum auction, which will give the provider the opportunity to gain capacity for super-fast mobile broadband.
The firm recently expressed concerns that some of its rivals, who still have spare 3G spectrum, may seek to delay the auction.
Three's Chief Executive Officer David Dyson told the BBC that he believes the auction will go ahead in 2012.
Should this be the case, then network congestion will not happen, he said.
"We have been assured by the government and Ofcom that distortions will be rebalanced when the auction happens," Mr Dyson added.
