5G Has Infrastructure Role: FCC, Qualcomm Chiefs

Much of the discussion has been on extending the reach of fiber networks, Rosenworcel said. “We really need to have robust connections to those towers … to make sure our wireless networks can deliver all that 5G has to offer.” About 50 million Americans are on 5G , Rosenworcel said. She noted the importance of 5G to IoT. Next-generation machine learning and artificial intelligence are “where the real 5G revolution comes,” she said. Rosenworcel said the FCC “made a mistake” last administration putting too much emphasis on high-band spectrum, repeating a criticism she made as a minority commissioner. Millimeter-wave 5G requires “lots of ground-based facilities,” which are “really costly” to deploy, she said. Mid-band is “the sweet spot” and “how we’re going to deploy 5G,” she said. “We’re doing a lot to fix where we were.” The FCC started the C-band auction, the first mid-band auction for 5G, under former Chairman Ajit Pai (see 2012080040). "The last FCC took unprecedented action to advance American leadership in 5G,” Pai emailed now. “A key part of that plan was freeing up spectrum for the commercial marketplace,” he said, noting the citizens broadband radio service and C-band auction. “Notably, today's leadership voted against each and every one of these measures,” he said: “The agency is now going backward on mid-band by putting on ice the 2.5 GHz auction and the 4.9 GHz initiative." Commissioner Brendan Carr "is proud that he voted in favor of freeing up more than six gigahertz of spectrum for licensed 5G services," a spokesperson emailed: “There is work ahead if this Commission is going to match the pace and cadence it hit with mid-band spectrum over the past few years.” Rosenworcel says the 2.5 GHz auction would come following the 3.45 GHz auction. Mid-band means more 5G outside urban centers, she said now. "That future is not quite here yet.” Broadband is becoming “critical infrastructure,” said Qualcomm CEO Cristiano Amon. Governments “should care,” he said. “I have not met a single government that does not worry about how they can build 5G and how fast.” Amon also noted the debate in Congress: “For the first time, you have a cellular technology that can really replace, or augment, fiber deployment,” which will be easier to build in rural areas. Amon predicted most major U.S. cities will have 5G in 2021, and it will cover the “majority of the country” by Dec. 31, 2022. Most Manufacturing Institute members report they hope to use 5G in their plants by year's end, said Executive Director Carolyn Lee: “They also recognize that the speed with which 5G is deployed will really impact their ability to be globally competitive.”
