CBRS Leading a Global Trend of Private 5G: H-P
The U.S.’ citizens broadband radio service approach has been at forefront of a global movement for private 5G, said Dave Wright, Hewlett-Packard head of global wireless policy, said at an FCBA spectrum CLE seminar Wednesday. CBRS commercial service has been…

available since 2020 in the U.S., and the FCC has authorized more than 500 devices in CBRS, and more than 4,300 professional installers are CBRS certified, he said. Beyond traditional spectrum access via licensing or unlicensed use, CBRS in the 3.5 GHz frequency range is a new approach in spectrum management by introducing a three-tiered sharing model, he said. Incumbents get protection from interference from priority access licenses and general authorized access, and PAL has priority over GAA, he said. One key difference in the U.S. approach is that no other country has used a dynamic framework like the U.S., and in most cases they're using local licenses instead, he said. Unlicensed spectrum is increasingly a linchpin for communications networks, with more devices using more data, said Alex Roytblat, Wi-Fi Alliance vice president-worldwide regulatory affairs. Telehealth, virtual reality and industrial IoT will require connectivity magnitudes faster than what's provided today by 5G, and opening up the 6 GHz band will help enable them, he said. That will require more use of local-area short-range communications and spectral reuse, he said. “The wide area network model is not going to be there to support our connectivity,” he said. The U.S. is unique in spectrum management with two agencies having authority -- the FCC regulating non-federal commercial use and NTIA regulating federal use such as by DOD, said Becky Tangren, NCTA associate general counsel. With spectrum increasingly crowded, the FCC is no longer as focused on exclusive access and is getting more creative in allowing access, such as via unlicensed bands, or shared use, she said. Some 2023 World Radiocommunication Conference agenda items will look at harmonizing frequencies for 5G, and WRC-2027 will likely look at what bands are to be used for 6G, she said.
