BDA (Bi-directional Amplifier) Large Coverage BDA covering the signal blind area BDA (Bi-directional Amplifier) for Blind Areas . For example Tunnels, Indoor coverage.

System Flexible Networking Completely IP Based ：“Why IP Technology? IP Technology is basis for converging networks IP Technology potentially allows for an easy and full-fledged integration in the existing IP infrastructure of the customer IP Technology holds potential cost advantages for network operators and promotes the use of standard HW (COTS) One IP/MPLS backbone network for several communication & data services Evolution from customer-specific or proprietary HW in IT environments IP Technology has become mature in offering high quality media services by MPLS, QoS Tagging and Traffic Shaping
