Since the Public Safety DAS market is very mature with many competitors in Denver, there needs to be significant cost and feature considerations when bidding for a project as large as these two towers. One of the biggest issues with creating a competitive solution was the sheer size of the buildings, with over one million square feet to cover. Utilizing a fiber distributed DAS would be too costly and complex to cover heavy stairwells and enclosed garage spaces as well.
Two Westell 2 watt, 90dB gain BDAs would be installed into the central location of each of the two towers. This would split the building in half instead of trying to cover it as one whole building. By locating them centrally, this would minimize coupler loss at the upper and lower end of the towers. The parking structure would be covered by running separate feed lines from the BDAs to better control RF power to each building. In addition, the Westell BDA provide additional features that the City of Denver requires, such as oscillation control and self-healing.
