Distributed Antenna Services (DAS) is a network architecture designed to improve wireless coverage and capacity within buildings or large areas where traditional cellular signals might be weak or inconsistent. DAS involves a network of distributed antennas connected to a central base station or a signal source, which helps to evenly distribute cellular or wireless signals throughout the facility.

This system enhances signal strength, reduces dead zones, and supports high-density environments like stadiums, shopping malls, or office buildings. By providing robust and reliable wireless connectivity, DAS ensures better performance for mobile users and supports a range of wireless technologies, including cellular, Wi-Fi, and public safety communications.
