Active DAS + CBRS

Active Distributed Antenna Systems (DAS) using Citizens Broadband Radio Service (CBRS) represent the next evolution of in-building wireless connectivity, merging the reliability and multi-operator flexibility of DAS with the agility and cost-effectiveness of shared spectrum. This architecture enables seamless indoor coverage across carriers and devices, a single secure infrastructure for both public and private cellular services, lower total cost of ownership, and readiness for 5G and beyond.

Active DAS using CBRS is more than an incremental improvement; it marks a fundamental shift in how in-building connectivity is designed, deployed, and managed. By combining the proven performance of Active DAS with the flexibility of shared spectrum, this model bridges the gap between mobile network operators and enterprises, aligning both around a shared, carrier-grade platform. As a result, CBRS-based Active DAS stands out as the most scalable, interoperable, and future-ready approach to indoor wireless.

Economic Efficiency

Eliminates dependency on complex operator-funded systems, lowering deployment and operational costs

Operational Simplicity, Security & Compliance

Cloud-based control, AI-driven optimization, and secure CBRS SAS coordination streamline operations and ensure compliance

Scalable Future-Proof Architecture

5G-ready architecture supports both public (MNO) and private networks— scalable and software-upgradeable for long-term viability

Wi-Fi Networks

Easy and cost effective to deploy but lacks the mobility, reliability, and security for enterprise-grade service

Small Cells

Strong localized coverage that requires dedicated spectrum and is typically a single operator network

Passive or Active DAS

Robust yet historically complex, costly, carrier-specific installations using licensed spectrum

Active DAS + CBRS

Combines the performance and multi-operator flexibility of DAS with the flexibility and cost efficiency of CBRS shared spectrum

Seamless Multi-carrier Connectivity

Deliver dependable, uninterrupted mobility for employees, customers, staff, digital services and more across buildings, campuses, and mixed-use developments

Secure and Flexible Network “Slices”

Create dedicated “lanes” for carrier, enterprise, and IoT traffic on one infrastructure ensuring performance and control

Public Safety and Compliance

Support in-building coverage mandates (e.g., for 911 access) and critical systems throughout public venues and large-scale spaces

Expanded Operator Coverage and Capacity

Extend indoor coverage and enhance capacity without consuming licensed spectrum or investing in complex bespoke systems

• Active DAS uses high-speed fiber connected radio heads and remote units to distribute RF signals with minimal loss and full digital control, providing uniform coverage, high capacity and positioning flexibility.
• The fiber-fed remote units convert digital signals to RF and actively manage output power and interference across multiple antennas. Within CBRS, each DAS transmission point is treated as a Citizens Broadband Radio Service Device (CBSD) and registered with the SAS, ensuring FCC Part 96 compliance.
• The Federated Wireless CBRS Spectrum Access System (SAS) platform and ESC network dynamically coordinate frequencies and ensure interference-free operation nationwide across CONUS and OCONUS regions.
• Combined with CBRS-based neutral-host frameworks one installation serves AT&T, T-Mobile and Verizon simultaneously as well as private 5G “network slices”.
