1. The Problem

A 797,000 sq ft D.C. data center had zero usable indoor cellular coverage due to dense construction, creating dead zones that hurt tenant experience and competitiveness.

A 797,000 sq ft data center in Washington, D.C. needed reliable indoor cellular coverage across common corridors and operational areas. The facility had no usable service from any carrier. Dense construction materials such as concrete, metal, and windowless interior spaces created complete cellular dead zones. This negatively affected tenant experience and reduced the building’s competitive appeal - when attracting new clients.

The customer initially approached RSRF after receiving a quote for a hybrid system from another vendor. After reviewing the design, RSRF recommended an ADRF Active DAS, which would provide stronger amplification across the large footprint and take advantage of the existing fiber network to support future expansion between building sites.

Our Process

Simple, from start to finish

1. Initial Budgetary Estimate
< 1 week
2. Design & On-Site Visit
1 to 3 weeks
3. Final Proposal
1 week
4. DAS Deployment
4-12 weeks upon approval

2. The Solution

RSRF designed and installed a 5G-ready ADRF Active DAS, using fiber-fed remotes and off-air donor signal to deliver reliable multi-carrier coverage across the massive facility.

RSRF performed a site survey and RF assessment that confirmed extremely low indoor signal levels. Data centers of this size often have a large footprint but low capacity requirements, which made it possible to bring in the donor signal off-air and avoid costly carrier signal sources.

RSRF designed and installed an ADRF Active DAS that provided coverage for all major carriers. Fiber-fed remote units delivered the power needed to overcome the concrete structure and metal racking and cabinets installed throughout the facility.

Installation required additional coordination because one of the tenants required escorted access, but the team maintained the project schedule without disrupting operations. Pre and post installation walk tests verified complete coverage and system performance.

3. The Results

The Active DAS delivered up to 25 dB stronger signal, improved SINR by 11 dB, restored full-bar coverage for all carriers, and led the customer to partner with RSRF on 20+ additional projects.

The Active DAS delivered immediate improvements in indoor coverage:

  • Signal strength increased by up to 25 dB
  • SINR improved by up to 11 dB
  • Strong and reliable service for all major carriers
  • Verizon improved from no bars to 5 bars throughout the building

Tenants, technicians, and employees now have consistent connectivity for voice, data, MFA tools, and day-to-day coordination.

RSRF completed the project ahead of schedule, within budget, and with better performance than the competing proposal. The customer has since partnered with RSRF on more than 20 additional projects.
