Exponentially rising data traffic, scarcity of spectrum, and expectations of enhanced user experience including 1Gbps data rates are driving operators to explore the use of shared spectrums such as CBRS – Citizens Broadband Radio Service. Operators can deploy LTE networks in 3.5 GHz CBRS spectrum using LAA. CBRS can be used in various business models including traditional mobile operators and new operators. CBRS also supports Private LTE networks. The course provides a high-level overview of the CBRS system, motivation for CBRS deployment, network architecture, network operation and deployment use cases.

A high-level technical overview to personnel involved in product management, marketing, planning, design, engineering, and operations.

After completing this course, the student will be able to:
• Define CBRS
• Differentiate among Incumbent Access (IA), Priority Access (PA) and General Authorized Access (GAA)
• Give examples of business models and use cases for CBRS
• Sketch the architecture of a CBRS-based network
• Describe the roles of a CBRS Device (CBSD), Spectrum Access System (SAS), and Environment Sensing Capability (ESC)
• Step through the life of a CBSD and UE in a CBRS deployment
