Key Bridge completed testing of its environmental sensing capability software for the citizens broadband radio service band, said a filing posted Monday in docket 15-319. NTIA initially required Key Bridge to complete testing with the agency’s Institute for Telecommunication Sciences by Dec. 31, 2020, but that was extended by a year due to “COVID-19 related access restrictions at the ITS laboratory,” the filing said.
CBRS
The Citizens Broadband Radio Service (CBRS) is designated unlicensed spectrum in the 3.5 GHz band created by the FCC as part of an effort to allow for shared federal and non-federal use of the band.
Dish Network said Thursday it’s working with FreedomFi on what it calls the “world's first community-driven” neutral host 5G hotspot network, using citizens broadband radio service spectrum. “This collaboration furthers DISH's position that the next generation of wireless networks can be cloud-native open source platforms, leveraging” open radio access network technology, Dish said. FreedomFi, meanwhile, said it's making available a consumer-deployable cellular base station, which uses CBRS spectrum.
Congress approved $50 million in the Infrastructure Investment and Jobs Act for a 3.1-3.45 GHz study, to be done by DOD, with the support of NTIA. Carriers had worked behind the scenes to oppose the allocation, which was a top priority of DOD, industry officials said. The legislation would give DOD 21 months to complete the study and says an auction can't start before May 31, 2025. Some say that's too much time and carriers can’t wait almost four years for more mid-band spectrum for 5G.
Charter Communications will launch a field trial early next year that pairs its Wi-Fi service with citizens broadband radio service (CBRS) band small cells for mobile subscribers, letting it offload wireless traffic that otherwise would be on Verizon's network through the companies' mobile virtual network operator (MVNO) agreement. The test will involve thousands of pole-mounted small cellsites in an unnamed designated market area, CEO Tom Rutledge said Friday as the company announced Q3 results. Charter bought 210 licenses in 106 counties in the 2020 CBRS auction. Rutledge said Wi-Fi with CBRS has "an opportunity to make a significant change" in how much traffic is on Charter's network vs. using the MVNO.
Incumbent informing capability, a new and sophisticated sharing technology that makes use of AI and machine learning, is a major NTIA focus, but the agency doesn’t have the congressional funding it needs to put IIC in place, experts told us. IIC would be the next generation of sharing, a more sophisticated version of what's being done in the citizens broadband radio service, replacing the environmental sensing capability (ESC) used in that band.
The Biden administration is looking past 5G to 6G, said Evelyn Remaley, NTIA acting administrator, at the Americas Spectrum Management Conference Wednesday. She's “very optimistic” about opening the 3.1-3.45 GHz band for 5G and sees industry support for developing a national spectrum strategy. Others cited the importance of the C-band and issues that must be addressed after the record-setting auction.
The FCC remains focused on opening the 3.1-3.45 GHz band for 5G, acting Chairwoman Jessica Rosenworcel told the Americas Spectrum Management Conference Tuesday. Other speakers said the U.S. is making progress on 5G, but it's a time of uncertainty and change on spectrum policy. Promoters had planned an in-person event but took it virtual with the rise in COVID-19 infections.
The FCC let spectrum access system administrator Amdocs use Key Bridge’s environmental sensing capability to protect federal incumbents in the citizens broadband radio service band. “Amdocs has demonstrated that its SAS can properly interoperate with Key Bridge’s ESC and that it will comply with all relevant provisions of the Commission’s part 96 rules,” said a Wednesday notice by the Wireless Bureau and Office of Engineering and Technology.
DOD is focused on making 3.1-3.45 GHz available for 5G, but doing so won’t be easy, said Vernita Harris, director-spectrum policy and programs, at the virtual NTIA Spectrum Policy Symposium Tuesday. Others said after the fights during the last administration, the Biden administration is improving coordination on sharing between federal agencies. The 3.1-3.45 GHz band is widely viewed as the most promising mid-band spectrum on the horizon for 5G.
Google asked for an emergency waiver of its commitment to be an environmental sensing capability administrator in the citizens broadband radio service, after its monitoring systems went down during Hurricane Ida. The sensor sites affected are in Plaquemines Parish, Louisiana, said a filing posted Tuesday, in docket 15-319. CommScope and Federated Wireless sought similar waivers last week.
