TeliaSonera Telenor have offered to sell up to 40 percent of a network infrastructure unit, part of their proposed Danish mobile deal to win over EU antitrust regulators worried about a lack of competition resulting from their deal. The novel proposal from the Swedish and Norwegian operators came after a first offer to sell two blocks of 2100 megahertz spectrum, and rent up to 15 percent of the merged Danish unit's network capacity to a new rival, received negative market feedback.
