Worth of White Spaces With Wireless Broadband on TV Airwaves

White Spaces are those section of TV airwaves that have hitherto remain unused by any of the TV channels. The FCC had recently approved the usage of these white spaces to be used for wireless broadband services. If that was to be the case, how much worth will the white spaces carry?

Annual revenues from white spaces in 15 years time : $3.9 billion to $7.3 billion

Chips needed to power white space devices will only need $10 a device by 2012, and this is expected to fall at a rate of 30% a year.
