It's All About the Airwaves

As a digital TV transition delay grows more likely, wireless companies that paid billions for the airwaves are crying "foul"

This week, the House passed a bill delaying the digital TV transition originally planned for February 17 to June 12. President Obama is expected to sign the bill, which would give your grandparents and Gossip Girl-addicted luddites another four months to ensure a broadcast signal by purchasing a digital television or government subsidized $40 convertor box.

The delay has been heralded by consumer advocates as a necessary measure to ensure that every American has the opportunity to make the transition from analog to digital broadcast television. 6.5 million households have still not made the jump and there have been problems with the government’s digital converter voucher program.

Television Signals Plug the Holes in GPS

GPS is indespensable, but reception is spotty indoors and in urban areas. A new system that uses digital television signals should clear the way for anytime, anywhere positioning

Today’s Global Positioning System is great for tracking tanks in the desert, but turn on your Garmin in New York City or inside virtually any building, and you’ll be staring at satellite static—GPS doesn’t perform well indoors or in urban canyons. Now a new technology is poised to pick up where GPS satellite signals cut out.
