A "3D" processor could make wireless communication more efficient according to scientists at the University of Florida. It could benefit both WiFi and cellular data services. One of the limitations of current WiFi tech is that it uses a "planar ... processor" to handle the wireless signal. Because these processors are (in practical terms) two-dimensional, they can only work with a limited range of wireless frequencies. Expanding the range of frequencies planar processors can handle is only possible by making them wider, a little like increasing capacity on roads. But making the ... (view more)

Fifty years ago, on April 3, 1973, Martin Cooper, an engineer at Motorola, made the world's first cellular phone call. Back then, making a phone call from a mobile device was a major achievement - but now, smartphones have become an indispensable ... part of our daily lives.
