Wireless carriers trying to block free broadband

Mobile telephone service providers are trying to block a plan to create a free, nationwide wireless broadband network by insisting on protections from interference that would make it impossible to deliver wireless broadband, according to the company proposing the network. Mobile carriers, led by T-Mobile, are insisting on interference protections for their existing spectrum that goes beyond any current protections and would disqualify several widely used products that currently emit low levels of energy in the radio spectrum, including microwave ovens and Wi-Fi equipment, said officials with M2Z Networks, a startup that proposed building a free wireless network on unused spectrum. The two sides are now arguing about the interference questions before the U.S. Federal Communications Commission, which has released its own proposal to auction spectrum for a free, nationwide network. Mobile carriers don't want a free broadband network that would compete with their own services, John Muleta, M2Z's CEO, said at a Monday press briefing previewing an M2Z filing to the FCC.
