The most heated battles over FCC chairman Julius Genachowski's new network neutrality proposal will involve its impact on wireless providers. Network neutrality attempts to ensure that Internet providers treat all traffic equally. Traditional landline-based providers have done so from the start, and the chairman's proposal merely aims to make sure they continue to do so. But wireless Internet providers have done just the opposite from the start. Thus the proposal, if enacted, would force them to change their businesses completely. And the biggest reason they will oppose that change is mobile VoIP.
