Australian IT is reporting that incumbent Telstra has been confirmed as the unknown bidder that successfully snagged the wireless spectrum of now-defunct operator Personal Broadband Australia (iBurst). iBurst’s spectrum was reported to have been sold just five days after the wireless broadband operator’s network was shut down on 19 December. Telstra has announced that it won a competitive tender process for the 5MHz of radio spectrum in the 1.9GHz band and the licence is valid until 2017. Having acquired the spectrum Telstra adds the cities of Adelaide, Brisbane, Melbourne, Perth and Sydney to the three existing areas where it has 1.9GHz licences; Canberra, Darwin and Hobart. Other operators that had reportedly shown an interest in the spectrum included BigAir, which revealed it had a bid rejected in October 2008 for the iBurst network.
