If you have a cellphone, you've probably heard the terms "3G," "4G" and maybe even "5G." They're all generations, or Gs, of cellular systems, ranging from the very first analog cellphones, which ran on 1G, to today's high-speed smartphones, which run on 4G.Researchers at the University of Arizona are working with industry on 5G -- even faster systems with extremely low latency, which means minimal delays in processing."5G is happening as we speak," said Marwan Krunz, Kenneth Von Behren Endowed Professor in the Department of Electrical and Computer Engineering at the University of Arizona. "It's a leap forward from 4G, both in terms of speed and in terms of what it can do. This low latency allows us to do things that were not imagined before: remote surgery, interactive vehicles, autonomous vehicles, which all require very rapid responses.
