Norway plans to auction off three blocks of mobile spectrum in the 1800-MHz band early next year.

The Norwegian Post and Telecommunications Authority (NPT) on Wednesday released a preliminary timeline for the allocation of spectrum left unsold in the country's late-2013 auction.

Interested parties will have until 12 January 2015 to register their intention to participate. The auction itself will begin on 26 January, the NPT said.

Like last year's spectrum award process, the regulator will seek to sell the remaining 1800-MHz spectrum via a multi-round ascending auction. It will publish its draft auction rules in September and finalise them by 8 December.

Norway raised 1.78 billion kroner (€210 million) from December's auction of frequencies in the 800-MHz, 900-MHz and 1800-MHz bands.

The biggest spender in the auction was Telco Data, which is owned by Access Industries, parent company of Norwegian mobile broadband provider Ice.net and Sweden and Denmark's Net 1. Telco Data agreed to pay NOK705 million for spectrum in all three bands.

TeliaSonera and Telenor also won spectrum in all bands with bids of NOK627 million and NOK453 million respectively.

Tele2 also took part in the auction, but did not win any spectrum.
