DS-9300
BDA (Bi-Directional Amplifier) is used to provide bidirectional communication between radio terminals and the base station in order to fit in any kind of environments. It can be used outdoors to extend the coverage range of base station, making communication services available in areas with no or weak signals. Additionally, it can be used indoors as the signal source to improve signal strength. With a multichannel selecting unit, BDA can selectively amplify the signals, ensuring the frequency purity of repeated signals and the stability of output power.
Features
Excellent hardware performance
low inter-modulation, high rejection, high isolation.
Network management platform
The network management system adopts the SNMP protocol, providing features such as site information identification,real-time data sampling, performance parameter setting, positive alarm report and automatically remote upgrade
Full digital processing
Supporting star, chain, ring and mixed networking, SDR technology is adopted to compensate the time delay, silence the uplink and downlink noise
