5G is coming soon. Already widespread in much of China, the next generation of mobile data transmission is being tested in cities across America and Europe. It will be 100 times faster than 4G/LTE and unleash a tidal wave of smart devices. Doctors will use it to carry out surgery remotely, taking advantage of its low latency to precisely control robots. Designers and lawyers will work remotely too, through shared virtual realities, and scientific experiments will be carried out over long distances, allowing scientists at opposite corners of the world to take part in common research projects.
