TPG and Vodafone were today announced as having placed the winning bids in Australia's latest spectrum auction. Telco TPG acquired the sole 2 x 10 MHz lot on offer, for for $1.26 billion.

my guess is that they plan to use a mix of the spectrum they just bought and wifi calling by turning broadband customers modems into hotspots to help fill in the backbone in areas where they have less dense coverage.
