The in-building Digital Distribution System that can simultaneously provide Digital DAS (Distributed Antenna System) and 2G & 3G Ethernet (with WiFi) Services allows you to resolve the shadow areas in your building.
Digital DAS relays signals to DHU (Donor Hub Unit) and MHU (Master Hub Unit) interworking with a base station (BTS, Node-B) via an optical cable and to SHU (Slave Hub Unit) and RU(Remote Unit) via a UTP Cable. The digital transmission is adopted from start to end points and the loss is much lower than that of the analog transmission so that you can build a more effective and efficient distribution network.
If you choose to use PoE(Power over Ethernet) for the RU (Remote Unit) at the end, you can operate the system without any separte power source due to its self-power supply system.
