E-Band operates at extended band 71-76 GHz and 81-86 GHz. The 1st-generation E-Band system, primarily used for enterprise networks, uses simple modulation techniques (for example, QPSK), with a transport rate of only 1 Gbit/s on 1 GHz or wider channels. It also lacks carrier-class Ethernet features and reliability.
Huawei’s 2nd-generation ultra-broadband E-Band microwave, which features high spectral efficiency and carrier-class reliability, is strategic for building next-generation mobile broadband networks. Huawei’s E-Band uses high-efficiency 64 QAM modulation to reach a transport rate of up to 2.5 Gbit/s (over 250 MHz channels), which will be further improved to a fiber-like capacity of 10 Gbit/s or higher. This significantly reduces bandwidth leasing costs. Huawei’s E-Band also offers a variety of carrier-class features, including Ethernet, packet clocks, bandwidth compression, and automatic bandwidth adjustment. Furthermore, it supports powerful network management functions.
“Huawei’s innovation in the microwave field is driven by a customer-centric strategy. To enable smooth evolution to all-IP networks, Huawei has taken the lead in launching IP microwave. Huawei will continue to unveil innovative products in the LTE era, helping customers cope with the upcoming bandwidth pressure and dense deployment of base stations,” said Jack Wang, president of Huawei’s transport network product line.
As a pioneer in the transport network field, Huawei is committed to providing operators worldwide with premium WDM/OTN, MSTP/Hybrid MSTP, and microwave products, as well as end-to-end transport solutions. According to consultancy firm Dell’Oro, Huawei ranks No. 2 in the global microwave market as of Q2 2012.
