CBRS Sharing Ecosystem Assessment

Summary

The objective of this project is to collect the data required for DISA DSO to ascertain the effectiveness of the sharing ecosystem between CBRS systems as managed by Spectrum Access Systems (SASs), and DoD systems as monitored by Environmental Sensing Capabilities (ESCs).  The five year project will provide insight into the sharing ecosystem’s effectiveness, and track changes in the spectrum environment over time. ​

Description

Background: In 2020, FCC auction 105 auctioned licenses in the Citizens Broadband Radio Service (CBRS).  CBRS (3.55 GHz to 3.7 GHz) has a three-tiered framework to accommodate shared federal and non-federal use of the band. The DoD 3.5 GHz Transition Plans focus on ecosystem validations, environmental assessments, and continued engagement on refining the CBRS infrastructure.  One component was identified for submission to NASCTN, to evaluate the effectiveness of the CBRS sharing ecosystem to co-exist with DoD radar systems, via independent trusted agent.
