About the feasibility of 4g systems. I feel that they have a bright future, if and only if the human understanding of the particulate nature of electromagnetic radiation is not enhanced to the level of manipulation and usage, and remains primitive as it current exists.
If organizations like CERN can manage to manipulate em-radiation communications at quantum level, then there will be quantum wireless communications. With Wifi already in the market, 3g, 4g will be a sure flop if such an innovation comes.
Of course the entry costs for any new internet rivals will depend on US Government or EU funding.
