It's nowhere near a sure thing, but the idea is percolating: Fearful of a spying China, members of the Trump administration's national security team say a mobile 5G network needs to be in the cards, and that maybe the government should be the one to build it. The news was first reported by Axios, which obtained a PowerPoint deck and memo that were drafted by a senior National Security Council official and shared within the administration. It outlines two paths to 5G: In one scenario, wireless providers build their own 5G networks; in the other, the feds build (and foot the bill for) one 5G network, which Axios says would "be an unprecedented nationalization of a historically private infrastructure" but "needed in order to create a secure pathway for emerging technologies like self-driving cars and virtual reality."
