Small cell traffic backhaul is a growing challenge as small cellsproliferate in 4G/LTE mobile infill situations and for other cellular areaswith patchy (or no) coverage. Millimeter-wave backhaul presents one solution tothis challenge and Xilinx has just announced IP to support millimeter-wave radio backhaul atdata rates to 1.6Gbps with future extensions planned to 10Gbps. The Xilinx 256QAM Millimeter Wave SmartCORE Modem IP solution supports point-to-point and multipointline-of-sight communications and addresses the needs of both 60GHz and 80GHzradio backhaul.

小基站设备（Small cell）流量回程正面临日益严峻的挑战 (Small Cell，这是因为一方面4G/LTE移动网络中的小基站数量激增，另外，宏基站之间的弱覆盖或者没覆盖的盲点也在增多，而毫米波回程是应对这个挑战的有效解决方案。赛灵思已经推出了支持毫米波无线回程IP，其速率可达1.6Gbps，未来速率将提到10Gbps，这个256QAM毫米波SmartCore modem IP 支持点对点以及多点视距通信，可以满足60GHz和80GHz无线回程需求。

All integrated versions of the modem are supported by the Zynq-7000 SoC,Kintex FPGAs, and the new Kintex UltraScale device family. The modemincorporates all PHY layer features including QPSK-256QAM modulation, 20-250MHzbandwidth support (optionally up to 500MHz), adaptive modulation, adaptive DPD,FEC, I/Q imbalance correction, automatic frequency recovery, and a hybriddecision-directed equalizer. Both 1GbE and 10GbE interfaces can be used aspayload interfaces. You can also use a CPRI interface for wireless fronthaulapplications.
