“This is going to change everything,” said Steve Perlman in a New York City hotel room in February, two days before revealing that his new start-up, Artemis Networks, plans to commercialize its pCell wireless technology. “We can deliver in 2014 all the goals of 5G on 4G phones,” he said, including more network capacity and faster, more reliable connections.

Many wireless experts aren’t convinced. “This is a promising technology, but some of the claims seem too good to be true,” says Lingjia Liu of the University of Kansas, in Lawrence.

When the COVID-19 pandemic erupted in early 2020, the world made an unprecedented shift to remote work. As a precaution, some Internet providers scaled back service levels temporarily, although that probably wasn’t necessary for countries in Asia, Europe, and North America, which were generally able to cope with the surge in demand caused by people teleworking (and binge-watching Netflix). That’s because most of their networks were overprovisioned, with more capacity than they usually need. But in countries without the same level of investment in network infrastructure, the picture was less rosy: Internet service providers (ISPs) in South Africa and Venezuela, for instance, reported significant strain.

But is overprovisioning the only way to ensure resilience? We don’t think so. To understand the alternative approach we’re championing, though, you first need to recall how the Internet works.
