US communications holding company AT&T (NYSE:T) announced on Friday that it has expanded its mobile broadband coverage at BWI Thurgood Marshall Airport, at Baltimore/Washington, by completing the installation of a new Distributed Antenna System (DAS) to serve customers throughout the facility.

The company said that a DAS installation consists of several strategically-placed antennas that distribute AT&T's wireless network coverage throughout BWI Thurgood Marshall Airport, providing for more efficient management of wireless capacity in heavily-trafficked areas. DAS reportedly has the ability to provide enhanced wireless coverage to customers in indoor or outdoor spaces where geographical limitations, or crowd density, might otherwise prevent an optimal wireless experience. This additional capacity is expected to help improve call reliability and enable more consistent network access to help customers make the most of their AT&T devices, the company said.
