Any thoughts on the up and coming 3.4GHz 5g spectrum Auction... currently scheduled for the end of this year but could be brought forward for the early adoption of 5G.
At the moment it will be uncapped, which means one carrier could take the lot.
Any carrier that doesn’t buy some, could be left in the 5G wilderness for 12-24 months. Until more spectrum is available.. What will TPG’s chequebook look like in November halfway through a rollout of a mobile network in Singapore and Australia. Beachfront 5G spectrum for Auction.. TPG spent over $1B for 10MHz at 700MHZ.... what bids do we get for 100MHz at 3400 MHz.. I suspect a number well north of $1B
