Local 5G DAS
A Local 5G Distributed Antenna System (DAS) consists of a network of small, low-power cellular base stations, known as small cells, distributed throughout a specific area such as a building or neighborhood. These small cells are connected to a central hub and work together to enhance cellular coverage and capacity, particularly in locations where traditional macrocell towers may be less effective.
