ZTE ZXSDR R8984E is a TDD 4 Path Remote Radio Unit that supports single-mode TD-LTE 4-path 4-carrier technology, and is used to construct indoor and outdoor macro networks and fill coverage holes. Its highlights include:

United platform: The ZXSDR R8984E is developed based on the unified SDR platform, which supports a smooth evolution to the new technologies in the future, and protects the operators' investment to the maximum extent.
Green and energy saving: The ZXSDR R8984E is small is size and light in weight, and uses multiple efficient power amplifier technologies, for example, CFR, DPD, and Doherty, and uses energy-saving technologies, for example, power amplifier voltage adjustment, decreasing the power consumption.
