AT&T Stadium, an 80,000 seat venue and home to the Dallas Cowboys, installed Westell’s ClearLink® Universal DAS Interface Tray (UDIT™), an active radio frequency (RF) DAS conditioner and management system that optimizes signal performance between a small cell or high power base station transceiver (BTS) and a DAS. A 300 point-of-interface (POI) configuration, AT&T Stadium IT management cites comprehensive remote monitoring of DAS alarms, RF parameters, and configurations via a web-based graphical user interface (GUI), as key benefits to the Westell solution.
AT&T Stadium was designed, purchased, and built to be upgraded to 50 sectors of MIMO across 3 different frequency bands for the first preseason game of the year. With Westell’s assistance, the AT&T Stadium was able to have additional sectors added on, with 850 MHz and 1900 MHz turned up by the first official home game of the year. Shortly after, the 700 MHz frequency was added. The low insertion loss of UDIT permitted flexibility in the DAS head end signal combining. Westell’s solution was able to service all four bands while ensuring continuous signal on the uplink and the downlink.
