Super-high frequencies could one day deliver your mobile video

Mobile operators want a way to keep urban users happy as they get more thirsty for data, and a professor in New York City thinks he’s found what they’re looking for.

In crowded cities, very high radio frequencies that most people had written off for use in cell networks might help carriers to stave off a feared bandwidth crunch for years, according to New York University’s Ted Rappaport. That’s why industry researchers are going to a conference in Brooklyn this week to talk about millimeter-wave wireless, an emerging technology that employs frequencies many times higher than those used today to carry cellular data. Equipment makers are also exploring the frequencies and think they could give an extra boost to the 5G technology coming around 2020.
