ComReg said that it will not rerun the auction for at least 12 months.
The spectrum was unassigned in a 2012 4G auction, which was aimed at promoting the roll-out of LTE in Ireland. The four successful 4G auction bidders were Vodafone, Three, Meteor and O2.
ComReg decided to award the unassigned 2x15MHz of 1800MHz spectrum – available for use until July 2015 – as three lots of 2x5MHz linked to specific frequencies within the band.
