Cellular coverage for real-time operations
Every moment in a transportation hub depends on real-time coordination and uninterrupted digital awareness. Passengers expect instant travel updates and intuitive movement from curb to gate, platform or terminal, while operational teams stay synchronized across concourses, tunnels, airfields, rail lines and back-of-house zones. Reliable end-to-end cellular coverage is now transportation infrastructure — as essential as signaling, public-safety systems and power. And in a tunnel there is no outside to add a tower to — the network has to be brought inside.
ANDREW® brings the mobile operators’ networks inside and distributes them across terminals and concourses, reinforced structures, underground platforms, supporting tunnel segments and multi-level parking facilities. Whether the answer is a building-wide distributed antenna system (DAS), targeted small cells or both, ANDREW designs it as a true neutral-host foundation — energy-efficient and ready to scale.
Challenges and opportunities
Reliable, end-to-end cellular coverage now shapes passenger experience and operational performance alike. This is where in-building cellular coverage matters most.
Passenger flow
Transportation hubs depend on mobile workflows requiring high bandwidth, low latency and reliable handoffs — the workflows that keep systems safe, efficient and on schedule across terminals, platforms and supporting underground areas:
Passenger experience
Transportation hubs rely on mobility and digital tools to improve passenger flow and engagement — reliable connectivity improves satisfaction, reduces delays and enhances the whole travel experience:
Safety & security
A rising ecosystem of mobile and connected systems depends on end-to-end coverage, and these systems must function everywhere — including reinforced structures, below-grade stations and back-of-house operational spaces:
Deployments
Large international airport terminals
Regional and commuter airports
Major rail stations and concourses
Subway and metro stations
Supporting tunnel environments
Intermodal hubs and passenger facilities

Frequently asked questions
Answers about indoor signal, DAS, small cells, carriers, Wi-Fi and underground coverage.
The macro network was built to cover ground, not to get through it. Reinforced terminal structures, deep concourses, below-grade platforms and tunnel segments absorb cellular signal — often enough to take a strong outdoor signal down to nothing before a passenger reaches the gate. Adding towers outside does not fix it, because the structure is the obstacle.
A DAS distributes every operator’s network across a large or complex building on one shared system; a small cell adds focused cellular capacity in a specific area. ANDREW offers both — the ERA® DAS platform and ONECELL® in-building small cells — and helps match the right approach, or a combination, to your terminal, station or system.
Yes. ANDREW’s platform is one infrastructure, approved by global operators, carrying public cellular, private networks and public safety from pre-4G through 5G.
Yes — they do different jobs. Wi-Fi carries the systems the operator runs — kiosks, back-office, baggage, building services. A DAS or small cell brings the operators’ cellular networks to every passenger on any carrier, and only cellular carries E911 that knows where the caller actually is rather than where the account is registered, Wireless Emergency Alerts to every device in the building and public-safety communications.
Yes — supporting tunnel segments and below-grade platforms are core to the design. One shared system carries every operator at once, so a passenger on one carrier and an operations lead on another have service on the same platform.
Proven. ANDREW’s all-digital DAS is operating at scale today on more than a decade of digital deployments, and is first to connect all three major U.S. operators, across every major RAN vendor, digitally on one DAS — deployed at scale, not promised on a roadmap.
Let’s discuss how ANDREW can help get you there.
