In-Building Wireless: DAS and BDA Systems



A Distributed Antenna System (DAS) is a reliable method for dealing with isolated spots of poor wireless coverage inside a large building or throughout a public venue. A DAS system works by installing a network of relatively small antennas throughout the building or area, which serve as repeaters. These small antennas are physically connected to a central controller, which is then connected to the wireless carrier network’s base station, providing seamless communications throughout the facility.


Distributed Antenna Systems (DAS) can be passive or active types:

Passive DAS grabs cellphone signals from antennas positioned on the roof, running them through cables throughout the building connected to the antennas. With Active DAS, the signal is passed from roof antennas or carrier-supplied base stations through fiber cables. Along the way, these active systems boost and amplify signals as needed. Both types of DAS Systems are transparent to mobile devices; providing both voice and data services to mobile devices just like any tower on a cellular network.


 ComtronICS' in-building DAS projects include:

university buildings  large athletic venues  hospitals  manufacturing facilities  casinos  malls 

Our customers include both carriers and self-maintaining end users.

Paul Brown Stadium

Cincinnati, OH

At Paul Brown Stadium, we installed a complete Tyco headend using a new technology called CDIU, which uses a CPRI fiber cable from a baseband unit, that then connects to the carrier via a CIAD unit. Once connected, it utilizes the Tyco infrastructure to distribute the signal and bypasses the high power remote units used with other systems.

University of Illinois

Chicago, IL

At the University of Illinois, we installed a complete multi-carrier BDA system in the dormitory's basement.

At Great American Ball Park, we installed a complete headend and Tyco stadium DAS system. The original system has been upgraded several times since its initial installation in order to keep current with the technologies and frequencies required by newer mobile devices.

We installed a complete Mobile Access system at Cincinnati Microwave.


At Cox Healthcare, we installed a complete DAS system throughout their multiple facilities.

At Memorial Hospital, we installed a complete multi-carrier DAS for public safety, covering multiple facilities.
