sDAS+ is a fiber Distributed Antenna System (DAS) to support dual band/multi carriers. With star chain topology, sDAS+ is good for building owner to support up to 8 different tenants.
sDAS is a fiber Distributed Antenna System (DAS). Each HEU can hook up six RAUs which can cover 9,000 sq. meter (10,000 sq. feet). The fiber distance between HEU and last RAU is up to 5km (3miles), this is far longer than using a coaxial cable and better for high building, elevator and campus.
