The ZXSDR R8972E is a new compact TD-LTE two-path Remote Radio Unit (RRU) with multiple carriers and high power, which was developed with Digital Pre-Distortion (DPD) technology, highly-efficient power amplifier technology and Software Defined Radio (SDR) technology. The ZXSDR R8972E and BBU form a complete eNodeB to achieve wireless transmission in coverage regions and control of wireless channels.

By using the ZTE unified SDR platform, the ZXSDR R8972E supports seamless evolution, protecting operators' investment to the utmost.

• Multi-carrier, seamless upgrade and Carrier Aggregation (CA) is used to increase system capacity.
• 2x2 MIMO, greatly optimizes the spectral efficiency and thus provides good user experience.

• The maximum output power of 80 W (2 x 40W) meets the multi-carrier requirement in in-depth coverage scenarios such as subways, tunnels, gyms and stadiums without trunk amplifiers.
• The high-power transmit mode can compensate for the long cable loss during sharing the antenna system with the 2G or 3G system, reducing the engineering installation difficulties and costs.

• The ZXSDR R8972E has a small size (the smallest size is 11.6L) and light weight (12.3 kg), facilitating transportation and engineering installation.
• The ZXSDR R8972E can be mounted on a pole or a wall without equipment rooms or auxiliary facilities. It supports AC and DC power supplies for rapid network deployment.
• The ZXSDR R8972E supports the cascade of RRUs to enable flexible network deployment.
