ZXSDR R8882 Product Description 1 Overview 1.1 Introduction ZXSDR R8882 (hereinafter R8882) is one distributed Remote Radio Unit (RRU) used in ZTE Uni-RAN total solution, with two transmitters. Based on the new generation of ZTE common RRU platform, R8882 can work in GSM, UMTS, LTE single mode or Multi-Mode. R8882 series includes R8882 2*60W, 2*40W, 2T2R and 2T4R. They have the same architecture; only differ from each other in power amplifier and physical vision.
ZXSDR R8882 Product Description R8882 supports GSM, UMTS, LTE or mixed technologies. It supports Multi-Mode at the same frequency band simultaneously. Instead of running hardware on independent platforms for each technology, operators can implement various wireless technologies through software configuration on the same hardware platform. It fully satisfies operators’ requirements of hybrid network deployment and long term evolution with low cost.
ZXSDR R8882 Product Description The differences between 2T2R and 2T4R modules include working bandwidth and number of receivers. In the physical appearance, R8882 2T4R has four antenna feeder interfaces but R8882 2T2R has two. The physical appearance is shown as follows. Figure 2-1 R8882 (2*60W) Physical Appearance Figure 2-2 R8882 (2*40W) Physical Appearance R8882 has two PAs, with both PAs working on the same bands, or one PA in 900MHz and the other in 1800MHz.
