If anyone has a crystal ball in which to see the future of wireless communications, it is Professor Andrea Goldsmith. In this interview, she mapped a future in which magic will happen everyday. Highways will monitor and guide their own traffic. Neurological disorders will be treated with simple electrical impulses. Some communications devices will consume so little energy that recharging as we know it will disappear. It is a vision of the future that draws closer each time Goldsmith describes it.
