Re: 2nd Class?
"I think they put cells in the tunnels in the cities and made the mobile companies share if I remember rightly."
The problem in the UK is that doing that (shared infrastructure) is explicitly illegal and would take regulation changes to sort out (Arguably this should have been done years ago)
It's the same problem which means you end up needing to have 3 separate farms of femtocells to provide coverage in a business/enterprise environment where mobile coverage is patchy-to-nonexistant.
