SAS - correct answer.Spectrum Access System CBRS - correct answer.Citizens Broadband Radio Service CPI - correct answer.Certified Professional Installer FCC - correct answer.Federal Communications Commission What is the purpose of CBRS? - correct answer.CBRS allows a range of RF bandwidth previously allocated to one licensed user to be shared among many users while maintaining that low priority users do not interfere with high priority users. What RF band does CBRS control? - correct answer.3550 MHz - 3700 MHz When and by who was CBRS created? - correct answer.Created by the FCC in 2015 What is the CBRS vision? - correct answer.150 Mhz of new wireless bandwidth that can be used for fixed or mobile broadband access. What does the SAS do? - correct answer.The SAS (Spectrum Access System) monitors all CBRS clients and receives information from CPI's that allows it to make sure that low priority users are not interfering with high priority users What are the advantages of a shared spectrum? - correct answer.Efficiency: lower priority users are able to use parts of RF spectrum that were previously allocated to a single user 100% of the time even when they weren't being used. Time To Market: It is very quick and easy for new companies to start using parts of the CBRS RF spectrum, where it used to take over 10 years to gain possession of bandwidth. Cost: It is completely free for a new business to begin using bandwidth, where companies do have the option to pay for higher priority. Before CBRS it used to cost billions of dollars to take possession of a range of bandwidth. What is an Aggregate Interference Constraint? - correct answer.Aggregate Interference Constraint refers to something that makes sure that interference seen by higher priority users is kept at a usable and acceptable level. Incumbents - correct answer.Tier 1 users who were using the CBRS band before the CBRS was created. What kind of architecture does CBRS use and what are the individual parts? - correct answer.CBRS uses a 3-tiered architecture in order to define who has priority over others.

What information does the SAS gather from individual devices? - correct answer.Location and Transmitting Information CBSD - correct answer.CBRS Device
