Why are China and the U.S. sparring over 5G?
Sino-American rivalry has loomed large through the 5G era, turning what was once a routine network-investment cycle into a geopolitical arms race. The Chinese and U.S. governments have each signaled their intent to control the future of 5G infrastructure not only in their home markets but around the world. Policymakers on both sides of the Pacific are hoping to reap the economic benefits that ultrafast cellular networks can offer their country’s private sector while controlling the technology used to build them.
China moved early to enhance its national infrastructure, blanketing the country with 5G base stations as soon as manufacturers started making them. The country’s three major mobile phone carriers anchored those transmitters to a dense network of fiber-optic cables and encouraged a range of businesses from seaports to coal mines to use the ultrafast connections. It has also provided subsidies and regulatory support to telecom operators and tech companies, facilitating their growth and enabling them to compete on a global scale.
At the end of June, 5G base stations in the country connected 676 million 5G phones and more than 2.12 billion Internet of Things devices, China’s central government officials said in a press conference in July.
U.S. officials offered their national cellphone carriers fewer direct subsidies than their Beijing counterparts, but policy makers granted many requests on the companies’ wish lists. Trump administration appointees fast-tracked auctions of 5G-capable wireless frequencies and consolidated the wireless sector by approving T-Mobile’s takeover of rival Sprint, a deal that the company and government leaders said would accelerate long-planned network upgrades.
At the same time, the U.S. has tried to persuade other countries to not buy Chinese gear—an effort that prompted some governments to ban its telecom equipment. But China’s homegrown supplier, Huawei, has weathered the U.S. efforts and played a pivotal role in both the domestic and global 5G markets. At the same time, they have turned away from Western suppliers like Qualcomm for some components and are now relying on domestic suppliers. Huawei remains the world’s largest seller of telecom equipment, commanding about a third of the global market, with sales about twice those of the second and third-ranked suppliers, Nokia and Ericsson, according to market research firm Dell’Oro Group.
What happened to businesses being big 5G consumers?
One of 5G’s most alluring promises remains the private network: a system built to the same standard as a high-speed cellphone service but tailored for a business operating in a smaller area like an office, farm or factory. Those networks can connect a range of computers, sensors, and robotics without the hassle and cost of hooking them up with wires.
For now, though, companies have been slow to adopt private networks. Consider “the factory of the future” that Ford and Vodafone previewed outside London in 2020. The companies detailed plans for a swarm of mobile robot welders receiving orders over superfast 5G connections, so they could assemble electric cars more quickly and precisely than traditional equipment.
Three years later, the factory of the future is still just a concept. Ford doesn’t use the high-tech wireless standard on its production line, and Vodafone says it ended its proof-of-concept project with the American automaker. A Ford spokesman didn’t respond to a request for comment.
In all, organizations have built more than 750 private cellular networks around the world, according to Besen Group, a private-network consultancy. Installations run the gamut from college campuses to open-pit mines, though many of them use less-advanced 4G gear instead of the latest-generation electronics.
That is partly because of a chicken-or-the-egg problem with private networks. A device maker might not want to create 5G gear for factories until more factories have installed cellular networks. But factory owners don’t want to invest in those networks unless there are enough 5G-ready devices on the market to justify the upgrade.
“This is actually fairly typical for new network equipment,” says Vodafone cloud and private-network chief Jenn Didoni. “The devices will certainly come, but there aren’t as many as in 4G, and they aren’t as tested and understood.”
Dell’Oro estimates that private networks make up less than 1% of the market for the relevant 5G equipment, but the research firm predicts that early revenue will grow, on average, at a 25% annual rate over the next five years as more connected gadgets hit the market.
“In the beginning, a lot of the conversations used to be about feasibility,” says Durga Malladi, a senior vice president at chip maker Qualcomm. “If I am interested in moving robots and overhead cranes using 5G, can I even get the same level of reliability and latency that I have expected from just wired? And the answer to that is, in almost all instances, absolutely yes.”

How has 5G affected the home internet business?
Many industries have yet to experience the market disruption that 5G’s boosters promised. A notable exception: Some telecom companies are enjoying a windfall from wireless bandwidth improvements at the expense of their cable-internet rivals.
Cellphone carriers like T-Mobile and Verizon have used new high-speed wireless equipment to beam internet service straight into customers’ homes, racking up more than five million new subscriptions altogether in under three years. The over-the-air service has dented cable-industry revenue and forced companies to compete in areas where they were once the only game in town.
Telecom companies have long known how to beam internet connections into people’s homes without the considerable expense of new wires and equipment. But wireless companies faced an uphill fight against their hard-wired competitors until 5G improvements brought advances such as more-efficient signals that could run through the same cell-tower antennas that companies were already installing to connect cellphones.
That helped mobile-network operators quickly rack up home-internet customers at much lower variable costs, especially in America, where cable companies’ dissatisfied customers offer a juicy target.
“The U.S. is very unusual because we pay so much for home broadband,” says Jeff Heynen, an analyst for Dell’Oro. “The way T-Mobile and Verizon are addressing the service, clearly you know who they’re going after.”
Markets with many far-flung customers, like Australia and Saudi Arabia, could soon follow the U.S. lead in 5G home-internet service, Heynen adds. Industry experts warn that the booming wireless-broadband business isn’t going to replace cable soon, however.
Capacity is the main factor holding back wireless internet services. A single cellular tower can only handle so many videogames, TV streams and Zoom calls at once, even after 5G upgrades offer those towers more bandwidth to go around.
T-Mobile CEO Mike Sievert has even played down his company’s booming home-internet business, telling investors at a Goldman Sachs conference in September that the service would eventually reach a customer base in the single-digit millions. That is a sliver of the more than 100 million U.S. households that could use broadband service.
“It’s a very mainstream offer, but we don’t think it’s going to take over cable and fiber,” Sievert said.
