“Spectrum is a limited resource,” Rotondo commented. “There certainly are better ways to use what we have.”
Rotondo pointed out that the trick with white-spaces spectrum is that it is used – and thereby only available – on a market-by-market basis. “In some urban markets there is little white-spaces spectrum, while there may be a lot of it in smaller markets,” he said.
While the FCC is now beginning the certification process for equipment that uses the spectrum, the ecosystem still needs to be developed. “Discovering that the spectrum can be used, freeing it up, making it available to others and developing a certification process, among other things, are not routine matters for the commission,” Rotondo added.
The article noted that xG is demonstrating that “junk” spectrum can be effectively put to use through its xMax carrier-class cognitive radio solution. This effort will not only help drive the white-spaces initiatives, but also pave the way to free up smaller blocks of spectrum, and not causing interference to other licensed users, thus bringing more spectrum to market.
