Wi-Fi and cellular networks are among the highest profile and most popular wireless technologies available to consumers. With newer technologies such as WiMax on the way the potential increases for interference because of careless use of the spectrum. "People are seeing a lot of more interesting things to do with spectrum - We need to be more efficient about what we have, because we can't make more," Intel Senior Fellow Kevin Kahn said in a CNET report.

The Federal Communications Commission (FCC) has been re-evaluating the use of the currently occupied wireless spectrum. Its recent efforts have involved freeing up over-the-air television broadcast spectrum. The television spectrum is particularly valuable because it's in the lower radio bands, which means signals with significant amounts of bandwidth per channel can be sent over a long range. Kahn added, "the industry is better off making spectrum more flexible" and "that he sees a day when technologies are developed to enable smoother transitions across networks".
