The technology uses gaps in radio spectrum, called 'white spaces', which exist in between frequency bands.

The superconductor's lack of resistance allows the firm to build filters that can chop a signal into much narrower frequency bands than a traditional filter.

ECONOMIST: Superconductors are starting to become useful

For example, 3G cell phones require multiple power amps (compared to one in each 2G phone) to support 2G and 3G air interface standards across multiple frequency bands.

Huawei Ascend P1 LTE is currently the device compatible with the highest number of frequency bands and is being tested on operators' networks across Europe, Latin America, North America, Asia-Pacific.

The freed-up airwaves in the proposal would mostly be unlicensed spectrum with "WiFi-like uses, " but at a much lower frequency than the 2.4GHz and 5GHz bands that WiFi needs today: as the first consistent, unlicensed spectrum at that range in the US, it could create opportunities for longer-ranged, free wireless that aren't even on the table in 2012.
