The two groups focused on ‘technical interworking’ with CBRS operation
Continuing the push to commercialize OnGo–the brand name for Citizens Broadband Radio Service-compatible products–the CBRS Alliance and the Alliance for Telecommunications Industry Solutions are collaborating to work some technical issues associated with shared use of the 3.5 GHz band.
Operators and other interests can access the CBRS band following a three-tiered model with incumbents at the top, priority access in the middle and general authorized access at the bottom. A spectrum access system prioritizes traffic to protect incumbent use, primarily by the U.S. Department of Defense, and other users. As the U.S. Federal Communications Commission decided in October, priority access licenses will be assigned on a per-county basis for a 10-year renewable term.
Specific to the work going on between the CBRS Alliance and ATIS, the goal is to detail how ATIS’ International Mobile Subscriber Identity, Home Network Identity and Priority Services will work over CBRS.
According to the two groups, because access to 3.5 GHz will be shared, not all users will hold a spectrum license but rather have access to certified base stations. “With such broad a low-cost access to the shared licensed spectrum,” the two groups said in a statement,” ATIS’ IMSI Oversight Council derived a strategy for allocating blocks of IMSIs for users with the 3.5 GHz CBRS band. Within the 3.5 GHz band, a shared HNI is used to identify CBRS operations, thus conserving HNI resources.”
ATIS President and CEO Susan Miller said the relationship “will continue our collaboration…which has been effective in creasing infrastructure to utilize the 3.5 GHz CBRS band for LTE services, while also advancing IoT applications.”
“Earlier this year, ATIS and the CBRS Alliance achieved a key milestone in enabling use of CBRS spectrum to improve mobile connectivity and make it more widely available,” said Susan Miller, President and CEO of ATIS. “This new agreement affirms that we will continue our collaboration with the CBRS Alliance, which has been effective in creating infrastructure to utilize the 3.5 GHz CBRS band for LTE services, while also advancing IoT applications.”
CBRS Alliance has laid out a number of use cases that fall into three broad categories: in-building, public spaces and industrial IoT. Within those categories, there are specific use cases covering everything from connecting multiple-dwelling units and healthcare facilities to supporting IoT implementations from manufacturers and utility interests.
