What is an Active DAS?

Active Distributed Antenna Systems use fiber optic cable to distribute signal between a centralized signal source and “remote nodes” placed around a building. The signal source is typically a “head-end” that combines signals from multiple carriers, which each need to provide their own signal source to the system, typically via their own fiber backhaul.

When additional capacity is needed, like in a football stadium or airport, an active DAS system is typically used. A state of the art active system can cover virtually any size of building and up to any capacity. Some of the most ambitious active DAS systems have been designed to cope with the load of over 70,000 Superbowl attendees, or the 2.47 million sq. ft. of coverage for 170,000 CES 2016 attendees.
