MDAS solution is called Multi-service digital distribution system access system, the working principle is as following :

1. System couple 2G, 3G and 4G signals from BTS via the access control unit.

2. Use the way of digital transmission, transmission to the proximal end of the extended unit by fiber optic, broadband access signal combiner in the extended unit.

3. And then transfer via Gigabit Ethernet port to several remote radio units.

4. After remote RF unit processed signal to digital, 2G, 3G and 4G signals through an antenna to achieve coverage.

5. While 4G signal use dual antennas to receive and transfer. Wideband signal through the Fast Ethernet port broadband network coverage.
