Trump national security officials are considering an unprecedented federal takeover of a portion of the nation's mobile network to guard against China, according to sensitive documents obtained by Axios.

Why it matters: We've got our hands on a PowerPoint deck and a memo — both produced by a senior National Security Council official — which were presented recently to senior officials at other agencies in the Trump administration.

The main points: The documents say America needs a centralized nationwide 5G network within three years. There'll be a fierce debate inside the Trump administration — and an outcry from the industry — over the next 6-8 months over how such a network is built and paid for. 

Two options laid out by the documents:

The U.S. government pays for and builds the single network — which would be an unprecedented nationalization of a historically private infrastructure.

An alternative plan where wireless providers build their own 5G networks that compete with one another — though the document says the downside is it could take longer and cost more. It argues that one of the "pros" of that plan is that it would cause "less commercial disruption" to the wireless industry than the government building a network.

Between the lines: A source familiar with the documents' drafting says Option 2 is really no option at all: a single centralized network is what's required to protect America against China and other bad actors.

The source said the internal White House debate will be over whether the U.S. government owns and builds the network or whether the carriers bind together in a consortium to build the network, an idea that would require them to put aside their business models to serve the country's greater good.
