Based on Caltta's advanced SDR platform, Caltta base station implements a distributed architecture that separates the baseband from the radio frequency (RF). It consists of B8200(BBU) and R8881(RRU) and is compatible with both digital and analog trunking.
World-leading SDR architecture, broader coverage.
Flexible networking with star and chain networks supported.
Optical fiber connection without feeder loss.
High sensitivity and better call quality.
Adapts multi-carrier technology, and realizes software expansion for cost savings.
High environmental adaptability.
Smooth evolution to 4G.
Frequency scanning to eliminate interference.
Efficient amplifier, natural heat dissipation, 80% power saving.
