The Trump re-election campaign’s wireless open access proposal was a poorly vetted scheme possibly intended to score political points. It was squelched almost immediately after it became public, as shocked White House staff members complained that it contradicted the administration’s support for competing wireless networks. The twist? Open access wireless is actually a terrific idea. Some forward-thinking Democrats and public interest advocates have been pushing it for decades.

The concept, promoted by Republican operatives such as Newt Gingrich and Karl Rove, is for a network supporting fifth-generation (5G) wireless technology to operate on a wholesale basis. Carriers such as AT&T, Comcast and Verizon could buy capacity. So could anyone else: Apple, Amazon, Walmart, Uber or small operators serving rural areas. No company could use exclusive control over spectrum to block competition.

Last year, a leaked National Security Council presentation called for nationalization of 5G networks to improve cybersecurity and better compete against China. The proposal was ignominiously killed and its author left the White House. The Trump re-election campaign’s proposal wisely dropped the government takeover. It shifted the focus to wholesale access, which could be overseen by an independent nonprofit organization, like the independent system operators that manage electricity markets.

Today’s cellphones use fourth-generation wireless technology, or 4G. 5G, a set of standards under development, promises higher speeds, improved coverage and better support for new technologies such as augmented reality, autonomous vehicles and connected sensors in all types of devices. 5G networks require denser construction of towers, reducing the distance between a tower and each device. To make 5G a reality, companies and consumers around the world will have to invest hundreds of billions of dollars over the next decade to upgrade hardware, phones and networks. The countries leading the way could reap huge economic benefits.
