Next year, fifth-generation wireless technology (5G) will begin to form the backbone of future economies and public services. It will touch every part of our lives, from cellphones to self-driving cars, to critical services such as electrical grids and water systems.
Unfortunately, the new infrastructure needed to support 5G can subject countries to threats to their national security. A major concern is that equipment might be installed by a company that can be controlled or swayed by a foreign government.
