The investment side of it would surely not be the issue which you think it would? I am not sure that outright coverage is really being improved upon these days anyway, the networks would still be free to fight the current battle for fast mobile data coverage.
Technically surely this isnt an issue, the issue would be financial rather than technical? Roaming itself isnt new, we do it every time we go to another country!![]()
No it isn't a technical issue as you say its a financial / competitive advantage issue, on the investment side I was talking more about future next generation roll outs / more 4G roll outs.
In the future, if an operator has invested in a site in some rural area, there wouldn't be an incentive for another operator to do the same as they could piggy back off someone else's. Yes a payment system could be set up so the owner of the site is compensated but the loser could end up being the customer with a service with less capacity.
