Microsoft, which has been pushing the use of TV white spaces to close the rural broadband divide, has joined with C Spire, Airspan Networks, Nokia and Siklu to form a coalition to come up with a "disruptive blueprint to close the adoption gap." The consortium will use Mississippi and Alabama as testbeds for driving affordable internet access and drive adoption. The consortium has not unveiled any of the potential technologies being tested—more details are supposed to be shared at the Mobile World Congress—but Microsoft made clear TV white spaces tech should be one of them.
