Not sure what they hope to achieve
Creating an open access mobile network a la fixed internet great idea. However the net neutrality debate gets a bit hotter in the mobile space. Any operator of this network will immediately become a victim of their own success, as people are freely connecting using their own services.
How do you attribute the right cost/revenue to the right user to allow you to invest in the network so that it performs adequately?
Who says this spectrum won't sell for Billions anyway? Apart from the economics of telecoms no longer supports such lunacy. Still going to cost a lot.
So this "open" network will be expensive when compared to fixed access, may have varying levels of QOS for service categories and will no doubt involve some throttling of blacklisted services such as p2p.
Doesn't sound so great now does it.........
