Call it the holy grail of radio transmissions if you must, but even if you're not about to toss that label on it, there's no question that the work being done in Stanford's engineering labs could destroy quite a few preconceived notions about wireless interference.

Baoli President QiangHua Shao said he sees significant opportunities in China and other Asian markets for Superconductor's SuperLink equipment, which reduces interference in wireless networks that leads to dropped and blocked calls.

Now, however, thanks to the dramatic decline in the cost of computer power, wireless devices are far cleverer, meaning that they can use spectrum more efficiently and are more tolerant of interference.
