ATIS and CBRS Alliance Collaborate to Advance Use of CBRS Spectrum
WASHINGTON, DC — ATIS and the CBRS Alliance today announced a successful collaboration that will enable Citizens Broadband Radio Service (CBRS) spectrum to be commercially deployed. The work took place in ATIS’ International Mobile Subscriber Identity (IMSI) Oversight Council (IOC) and has resulted in a solution to support the use of CBRS spectrum to aid in providing mobile connectivity service in locations such as stadiums, apartment buildings, malls and other large facilities – as well as for other uses as they evolve.
The IOC oversees the U.S. assignment of the limited IMSI resource, a critical 15-digit international identifier that allows for network roaming. Through the IOC, and in collaboration with CBRS Alliance, ATIS developed an innovative new IMSI code that is specifically allocated for use by CBRS spectrum operators. IOC will also begin administration of an IMSI Block Number (IBN), under the oversight of the IMSI Administrator, iconectiv. The IBN will be assigned to CBRS spectrum operators to support the implementation of network services. This work is essential for utilizing CBRS for LTE services while also advancing IoT applications.
