The only DAS digitally connecting every major RAN vendor through both CPRI and O-RAN.
Fast, reliable in-building connectivity is no longer optional — it’s expected. Across stadiums, airports, hospitals, offices, factories, and campuses, people demand seamless, high-performance mobile service everywhere they go.
A distributed antenna system brings mobile operator signals into a building or venue and distributes them throughout the space to provide reliable cellular coverage and capacity.
The ANDREW® ERA® Distributed Antenna System meets that demand with a proven all-digital architecture and native CPRI and Open RAN (O-RAN)—an industry first, and the only DAS to digitally connect every major RAN vendor over both. ERA is deployed and operating in live networks today.
Why ERA?
ERA simplifies in-building wireless with a flexible, software-defined architecture designed for operators, venues and enterprise networks.
Any venue. Any operator. Any technology. One infrastructure, approved by global operators, for public wireless, private networks and public safety—from 2G through 5G.
Local. Campus. Cloud-RAN. Place the RAN where it makes sense—on-site, across a campus or centralized remotely—with low-, medium- and high-power radios matched to the venue.
CPRI and O-RAN. Both. Today. Evolvable. An industry first: ERA digitally connects every major RAN vendor to the DAS through CPRI and O-RAN.
No analog RF in the headend or transport. No radio heads, POI systems or RF combining in the headend, reducing traditional sources of PIM. The signal remains digital from the baseband to the DAS radio.
Performance that’s measured. Throughput, signal-quality and latency gains validated in live, high-density deployments.
Smaller. Cooler. Greener. Less headend space, fewer RF components, lower power consumption and reduced cooling.
Simple to deploy. Intelligent to operate. Zero-touch configuration, software-defined routing, real-time visibility and built-in security—from deployment through operations.
Lower CAPEX. Lower OPEX. Fewer RF components, software-based expansion and fewer site visits.
Proven. Not promised. Digital CPRI and O-RAN connecting operators in live networks today.
Digital since 2014. More than a decade of digital DAS innovation—and still advancing.

Common questions
Quick answers about ERA architecture, network support, efficiency and real-world deployment.
ERA is ANDREW’s all-digital distributed antenna system (DAS): a modular platform that distributes multi-operator cellular signal digitally throughout a building, with native CPRI and O-RAN support across 2G through 5G.
Yes—natively. ERA digitally connects every major RAN vendor to the DAS through CPRI and O-RAN, eliminating the need for an analog RF headend.
ERA supports public, private and public-safety networks across 2G, 3G, 4G and 5G FDD and TDD, plus cellular IoT protocols including LTE Cat M1 and NB-IoT. Its architecture is carrier-, band- and technology-agnostic.
Compared with a traditional analog DAS, ERA can reduce the headend footprint by up to 90% and lower power and cooling requirements by as much as 55%. Its next-generation access points use up to 40% less energy.
Yes. ERA operates in live, high-density venues on a platform backed by more than a decade of ANDREW digital DAS deployments. Live deployments have demonstrated approximately 30% better signal quality and throughput and up to 98% lower latency.
A traditional analog DAS typically requires radio heads, point-of-interface (POI) systems, and RF combining hardware in the headend. ERA keeps the signal digital from the baseband to the DAS radio, reducing RF hardware, headend space, power, and cooling.
