Global investment bank coverage

A global investment bank brings cellular coverage into its new corporate campus



Global investment bank moves to a modern 7-story complex, but has no indoor cellular coverage.


CEL-FI QUATRA active DAS Hybrid


  • Installation of a CEL-FI QUATRA system within 3 weeks
  • About a third of the cost of an active DAS
  • Full cellular coverage with plans to extend to other parts of the complex

The Challenge

During the renovations the IT installers were having trouble getting cell signal and were experiencing dropped calls, so the bank approached one of the carriers for a solution. Historically a traditional active Distributed Antenna System (DAS) would have been recommended by the carrier, but this was off the table because it would have taken a year to install and employees were moving into the building in two months. So instead, the carrier recommended CEL-FI QUATRA, an active DAS hybrid. The bank engaged Atlantic Technology Group based in Maryland to install the solution.

“The building is beautiful, but the new windows blocked out RF signals from penetrating indoors. This is a common problem in new buildings,” explains Dan Connelly, founder and owner of Atlantic Technology Group. “We put together a proposal to improve the customer’s cell reception for all four carriers – Verizon, AT&T, T-Mobile and Sprint. We could install the CEL-FI QUATRA system within a few weeks at about a third of the cost of an active DAS.”

The Solution

The six floors of the building, five above ground and one below, are each 55,000 square feet. Each floor was fitted with two CEL-FI QUATRA Network Units (NUs), the headends of the system—one to provide coverage for AT&T and Verizon subscribers, and the other for T-Mobile and Sprint customers. Each NU was then connected by ethernet cable to four Coverage Units (CUs), the remote units that distribute the signal to provide strong, uniform coverage throughout the floor. A total of 12 NUs and 48 CUs were installed in the building. Six CEL-FI Wideband Omni Donor antennas were placed on the roof to provide strong donor signal.
Atlantic Technology Group used the CEL-FI WAVE remote monitoring and management platform to manage the installation. Connelly explains, “We always use the Cel-Fo WAVE app. After we attach the network unit, we log into the CEL-FI WAVE app remotely with a cellular router and made sure that we have a really good donor signal and the rooftop antennas are optimized. We make sure that the coverage units have sufficient gain. Then finally we walk the floor with the client, just to make sure everybody’s happy with the end result.”

The Results

The customer was happy. The installation was complete within three weeks. “We went from zero to one bar in some areas of the building to three or four bars. The customer was pleased we resolved the coverage problems before the employees moved in,” says Connelly.”

Atlantic Technology Group plans to outfit the bank’s underground parking garage with a CEL-FI GO Smart Signal Booster in the near future.
