White Spaces Worth Some Money
The FCC recently made the decision to leave the white spaces unlicensed much to the chagrin of broadcasters who currently use the spectrum for wireless microphones. Tech companies such as Google and Microsoft see this as the next generation wireless opportunity as they can provide tools and services more cheaply by leveraging this spectrum without the additional cost of licensing and managing the spectrum.
According to the report, spectrum sensing will soon become mandatory technology for those wishing to use the white spaces. For an overview of the report check out this site. You can find the full FCC order here.
