Overview of CBRS
TPR1039d | On-Demand | 5G Access | 2
Course Duration: 4 hours
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.
Intended Audience
A high-level technical overview to personnel involved in product management, marketing, planning, design, engineering, and operations.
Objectives

■ Define CBRS
■ Differentiate Tiered licensing structure: IA, PAL and GAA
■ Give examples of use cases for CBRS
■ Sketch the architecture of a CBRS-based network
■ Describe the roles of a CBSD, SAS, and ESC
■ Step through key operations of CBRS
