I guess the problem is it's a shared medium. In many European countries, LTE (4G) rollout has been used as an excuse to halt investment in the DSL connectivity of rural areas. The results thus far have been disappointing, with LTE cells already becoming overloaded where no sensible DSL speeds are available. And that's with the severe volume caps that come with LTE contracts.
