| Samsung initially launched CBRS-certified products late last year and now expanded availability to all mobile operators. Bringing broadband service to underserved areas through fixed wireless access over 3.5 GHz spectrum is one of the key use cases called out by Samsung’s Head of Customer Technology Solutions Sanjay Kodali in a blog post about the vendor’s CBRS gear.Roughly two years ago in September 2018, AT&T picked Samsung to supply its 5G-ready CBRS gear and discussed plans to use spectrum in the 3.5 GHz band to expand its fixed wireless access network. AT&T said it would use Samsung’s CBRS-compliant radios and base station equipment, and tap CommScope as the Spectrum Access System (SAS) provider.In Kodali’s post, he emphasized that operators can add new radios to existing cellular sites to deliver wireless broadband more cost effectively than by using a cable or fiber approach. Kodali noted those options can pose a challenge in many underserved areas because of the cost and time associated with getting access to right-of-ways and needing to dig to lay down new cables or fiber. Samsung already has a foothold in next-gen networks in the U.S., supporting both AT&T and Verizon’s 5G rollouts. It has also deployed “tens of thousands of mid-band Massive MIMO radios” in South Korea, which Kodali suggested gives Samsung proven experience for commercial deployments looking ahead in the C-band. The FCC’s much anticipated C-band auction is slated to kick off in December, offering 280 MHz of key mid-band spectrum for 5G. At this point, most 5G deployments in the U.S. have either used millimeter wave or low-band frequencies, and mid-band resources for 5G have been scarce. T-Mobile is the exception and actively working to turn on a deep pool of 2.5 GHz spectrum previously held by Sprint before the two carriers merged in April. -- ???????? | |||
