A distributed antenna system (DAS) is a network of spatially separated antennas connected to a common source. This system enhances wireless communication by improving signal strength and coverage in areas where traditional antennas may struggle, such as large buildings or urban environments. DAS can support various wireless technologies, including cellular networks and Wi-Fi. DAS works by distributing the signal from a central point to multiple antennas placed throughout a designated area. This setup reduces dead zones and provides better service quality for users. It is commonly used in venues like stadiums, airports, and shopping malls to ensure reliable connectivity for many users simultaneously.
