At the Mobile World Congress 2017 (MWC 2017) in Barcelona, Huawei unveiled 5G-oriented microwave bearer solution. Featuring ultra-high bandwidth, ultra-low latency, and cloud readiness, it supports 5G application scenarios, helping operators manage future challenges to 5G bearer networks.
5G application scenarios include enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communications (uRLLC), and massive Machine Type Communications (mMTC). The IMT-2020 report, published by ITU, defined 5G and laid out its requirements, specifying that 5G should support 10 Gb/s per user, 1 ms latency, and 1 million device connections per square kilometer. To meet the challenging requirements on bandwidth, latency, and flexibility, Huawei has developed its 5G-oriented microwave bearer solution, which features the following:
- Ultra-high bandwidth: 20 Gb/s
Huawei’s solution maximizes the value of the microwave spectrum through super dual band and large capacity E-band technologies to provide 10 to 20 Gb/s broadband access, meeting the requirements of carrier customers. Huawei is also actively researching D-band (110 to 170 GHz) and W-band (75 to 110 GHz), and is facilitating the development of standards that will support the smooth evolution to 50 – 100 Gb/s.
- Ultra-low latency: less than 100 μs
To reduce the per-hop microwave latency from hundreds of μs to tens of μs, Huawei uses its own chips and optimization algorithms in its solution. This fulfills the requirement for ultra-low latency. In addition, routing microwave allows for more flexible deployment of mobile bearer networks, reducing the latency of X2/eX2 services in LTE and LTE-A scenarios.
- Cloud readiness: improving efficiency and meeting multi-service requirements
Using Huawei’s All-Cloud Network architecture, the 5G-oriented microwave bearer solution significantly improves the efficiency of network operations, enables agile service provisioning, and reduces OPEX. Combined with the sub-solutions of Huawei’s All-Cloud Network solution, the 5G-oriented microwave bearer solution can efficiently transmit different services.
The launch of the 5G-oriented microwave bearer solution will drive the evolution of the microwave industry towards large bandwidth, low latency, and cloud readiness to enable the business success of operators.
