5G application scenarios include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communication (URLLC), and Massive Machine Type Communication (mMTC). The IMT-2020 report, published by the ITU, defined 5G and laid out its requirements, specifying that 5G should support 10 Gbit/s per user, 1 ms latency, and 1 million device connections per square kilometer. These requirements pose a brand new challenge for bandwidth, latency, and flexibility of bearer networks. In practice, 5G deployment is very complex.
As the number of 5G base stations continues to increase, the fiber to the mobile base station (FTTM) rate becomes low and limited CAPEX budgets become apparent. This creates huge demands for microwave transport. Data shows that about 50%–60% of the world’s mobile base stations have used microwave backhaul. Therefore, 5G transport using legacy microwave links is also a focus for global operators.
To address operators’ 5G bearer requirements, Huawei has launched a next-generation 5G microwave bearer solution, which features the following:
- 10 Gbit/s-to-site
Huawei’s 5G microwave bearer solution uses both the intra-band carrier aggregation technology and inter-band Super Dual Band and MIMO technologies to provide a maximum of 10GE to the site, meeting the requirements of evolving most base stations towards 5G. In addition, 8192QAM modulation, 112/224 MHz channel bandwidth, and co-frequency interference cancellation technologies can be used together to increase the bandwidth of common bands.
With the unique chip and innovative algorithm developed by Huawei, Huawei is currently the world’s only microwave solution vendor that has the ability to aggregate four carriers for common bands. Through the carrier aggregation technology, operators not only significantly increase single-site microwave transmission bandwidth but also greatly reduce engineering and installation costs caused by network upgrade or evolution. More importantly, the carrier aggregation technology helps reduce the tower space by 50%.
- Smooth evolution
“Smooth upgrade and no worries for 10 years” is Huawei’s commitment to customers. Huawei’s 5G microwave bearer solution is dedicated to help customers maximize the use of their assets on the live network to meet 5G bearer requirements. With the carrier aggregation technology, hardware deployment and multiple software upgrades can be performed to smoothly match the traffic growth on the wireless side, minimizing customers’ initial CAPEX investment. Super Dual Band can also be employed to integrate common-band microwave on the live network with E-band microwave to achieve a significant bandwidth increase from hundreds of Mbps to the maximum of 10 Gbit/s. The modular antenna design can keep the antenna body unchanged and transform single-polarized antennas to dual-polarized antennas by replacing only feeders, achieving an improvement from common-band antennas to E-band antennas.
