Multi-Carrier DAS Engineered for Data Center Environments

Situation

As data center operations become increasingly complex, dependable in‑building wireless connectivity is critical for day‑to‑day on‑site teams, safety, and service providers. Our customer, one of the largest global carrier-neutral data center companies, needed consistent cellular coverage inside one of its facilities to maintain a high‑performance data center environment.

Requirements

The in-building wireless solution would need to:

• Deliver reliable cellular coverage throughout approximately 100,000 square feet of interior corridor space
• Support multiple carriers, including AT&T, Verizon, and T‑Mobile, on a shared system
• Minimize disruption to ongoing data center operations
• Meet carrier design standards and approval requirements
• Be deployed seamlessly from initial assessment through activation and documentation

Key Project Highlights

Our team delivered a comprehensive in-building Distributed Antenna System (DAS) solution tailored to the unique requirements of a data center environment.

• RF Coverage Assessment
  The project began with a detailed site walk and RF analysis to evaluate existing signal strength and identify coverage gaps across the facility’s corridors.
• Custom System Design
  Using the collected RF data and building layouts, our team engineered a DAS design optimized for corridor coverage, performance, and future scalability.
• Carrier Coordination and Approvals
  NTI managed the full carrier engagement and approval process with AT&T, T‑Mobile, and Verizon, streamlining what is often one of the most time‑consuming phases of DAS deployment.
• Equipment Procurement and Installation
  The project included installation of rooftop donor antennas & sleepers, a dedicated DAS head‑end, and strategically placed in‑building antennas in alignment with data center operational constraints.
• System Activation and Optimization
  Once the system was installed, our team commissioned and activated it across all three carriers, with coverage verified against design specifications.
• Project Closeout and Documentation
  The team delivered a complete closeout package, including as‑built drawings, test results, and system documentation to support ongoing operations and compliance needs.

Results

• Improved indoor cellular reliability
• Activated multi‑carrier cellular service for AT&T, Verizon, and T‑Mobile
• Reduced operational friction for on‑site personnel and service teams

What’s Next?

This DAS project in a large colocation data center demonstrates how a proactive, end‑to‑end approach to in‑building wireless can simplify deployment while delivering reliable results in mission‑critical environments. While this project scope was limited to cellular, we also partner with data center owners, developers, and operators to design and build full solutions for public safety and 2-way radio connectivity including:

• Assessing current and future in‑building connectivity needs
• Designing carrier‑approved, scalable DAS systems
• Managing approvals, installation, activation, and documentation
• Delivering wireless connectivity that supports efficient data center operations and long‑term growth
