The facility is built for security. Cellular signal still needs to get in.
Cellular coverage for mission-critical facilities
A data center is engineered to keep the outside out - poured concrete, structural steel, EMI shielding, no windows by design, and whole halls below grade. All of it stops a cellular signal at the door. The compute and storage run on infrastructure the operator owns; the people do not. Technicians, security, vendors and first responders move through the building on their own phones, on carriers the operator does not run.
That is a safety problem before it is a convenience one. A lone technician in a hot aisle has to be able to call for help. ANDREW® brings the mobile operators’ networks inside and distributes them across data halls, below-grade plant, electrical and UPS rooms, meet-me rooms, docks and generator yards. 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
In a building engineered to block a signal, this is where in-building cellular coverage matters most.
Safety
The people who keep a data center running work alone, around high voltage and high heat, in spaces built to block a signal. Reliable coverage lets a lone worker call for help and an emergency call pinpoint where they are.
Operations
When something goes wrong, minutes matter. Technicians, vendors and on-call engineers coordinate across the floor, down the levels and out to the plant. Connectivity everywhere is what keeps a response moving.
Security
The guard force, escorts and contractors coordinate across a footprint measured in acres, on their own phones - and the perimeter, docks and yards need coverage as much as the halls do.

Frequently asked questions
Answers about signal penetration, DAS, small cells, carriers, Wi-Fi and below-grade coverage.
The macro network was built to cover ground, not to get through it. A data center is the extreme case — poured concrete, structural steel, EMI shielding, no windows by design, and hall after hall of racks that stop a signal a hundred rows deep. A strong signal in the parking lot is nothing by the second row of the first hall. Adding towers outside does not fix it, because the building was built, on purpose, to keep the outside out.
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 facility or campus.
Yes. ANDREW’s platform is one infrastructure, approved by global operators, carrying public cellular, private networks and public safety from pre-4G through 5G - and it is live across all three major U.S. operators.
Yes - they do different jobs. A data center’s networks — production, out-of-band, corporate, building — are among the most controlled anywhere, locked down on purpose, and none of them is the cellular network in a technician’s pocket. A DAS or small cell brings the mobile operators’ cellular networks to staff, vendors, contractors and responders on their own phones. Cellular also carries E911 with accurate location, Wireless Emergency Alerts and public-safety communications.
Yes. Those sealed, RF-hostile spaces are exactly the design target, so technicians, security and responders keep coverage from the hottest aisle to the lowest level.
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.
