Is the CBRS Spectrum Planned For Integration With Nextgen Active/Digital DAS Systems?

Reliable sources indicate that CBRS may soon integrate with Active/Digital DAS systems—a significant development that was previously not feasible. This potential advancement could change how the CBRS spectrum is deployed, offering new possibilities for both private and public network solutions.
Impact on Standards and Private 5G Market Adoption
If confirmed, this integration could lead to the development of new industry standards, best practices, and numerous product development opportunities, particularly for Private and Public Neutral Host “DAS” systems. The enterprise market may experience more widespread adoption, offering enhanced control of system and enabling third parties to fund and deploy neutral host DAS systems (with the CBRS layer of DAS pie funded by enterprises), while providing a future pathway for upgrades on licensed spectrum if MNOs choose to participate. TCO could become tricky with many different configurations and CBRS Private 5G blend.
Integrating CBRS spectrum into next-gen DAS systems could revolutionize cost-effective simulcasting and enable rapid deployment of neutral-host solutions, attracting MNO interest from day one or when conditions become favorable on business terms with Private & Public ROI Model. Third-party companies with capital may aggressively target commercial real estate, where outdated systems need swift upgrades.
CBSD EIRP Limits and Nextgen DAS Solutions
The current Class-A CBSD EIRP limit of 30 dBm supports the case for low- and mid-power Neutral Host DAS solutions. Here, you can expect a maximum power radio of 30 dBm located in the headend, connecting with C-Band or CBRS low-power points of interconnection (POI) and simulcasting through Fiber DAS, utilizing Active or Digital intelligence. However, high-power DAS products—especially those relying on passive distribution—may face challenges in this new landscape due to 30dBm CBSD EIRP rule. Fiber-to-Edge DAS could become increasingly popular, and DAS products may need to evolve, factoring CBRS power levels into their overall link budget designs.
Future FCC Regulations
I remain hopeful that the FCC will revisit and improve the indoor power limits for Class A CBSDs, which could provide greater flexibility in DAS Product Development Roadmap. Next-generation DAS systems will require intelligent design to ensure compliance with the current 30 dBm limit. Designing with some buffer could be advantageous, should FCC regulations shift in the future.
Impact on Design Tools
In light of these changes, tools like iBwave, Atoll, and any future Gen-AI/ML-based design platforms will require updates to support new component files and guidelines, ensuring that they remain aligned with emerging CBRS and Nextgen DAS standards.
Speculation or Reality 
The coming months may clarify the feasibility of a CBRS solution through Active DAS/Digital DAS. We will also observe how the SAS will interact with CBSD in cases of simulcasting. Stay tuned!
