Battles of the Bands

I heard about this problem a couple months ago. Today's WaPo has a good summary. It seems that a wireless broadband network presently under development may cripple aviation GPS (and many consumer receivers as well):

Two of 21st-century America’s favorite gadgets — the smartphone and the GPS device — are on a collision course, according to a report delivered Friday to the Federal Aviation Administration.

The report says deployment of a massive new network of towers and satellites to expand wireless communication may effectively shut down Global Positioning System devices that are at the core of a multibillion-dollar plan to revolutionize aviation. They also may affect some GPS units used by drivers, bicyclists and boaters.

Whoops.
