Huawei innovatively proposes Super Dual Band solution based on AM, QOS and EPLA technology, binding traditional band and E-Band. Traditional band realizes 500Mbps with 99.999% availability. E-Band provides 4Gbps higher bandwidth while reducing availability to 99.9% for extending distance. Take rain zone K for instance, the transmission distance can reach 5.32km at 4.5Gbps, and farther to 12km at1.2Gbps.
