Europe's 5G wake-up call

Whereas the battle over 4G was essentially commercial, focusing on job creation and profits, the ongoing 5G debate is about geopolitics, technological leadership, and national security

How times change. Not so long ago, the next big thing in telecommunications was 4G mobile networks, which promised massive data transfers and cheap voice calls. Now comes 5G, which will potentially spur all sorts of new digital innovations, thanks to its greater speed (200 times faster than 4G), faster data transfers from wireless broadband networks, and, most important, the ability to connect cyber-physical objects in the context of the Internet of things. Moreover, 5G is expected to enable the much more rapid reaction times required for driverless cars, advanced factory automation, smart cities, e-health, and many other applications.
