[Shenzhen, China, September 21, 2017] Huawei announces that its Blade optical transport network (OTN) solution will assist China Telecom (Liaoning) in building a 5G-oriented cloud radio access network (C-RAN) fronthaul network. These fronthaul networks will enable Liaoning Telecom to effectively cope with denser site deployment requirements in the future 5G era in addition to further improving the existing 4G network coverage. As a result, Liaoning Telecom can greatly improve users' access bandwidth and user experience of mobile broadband access.
To meet the ever-increasing user experience requirements of mobile broadband, Liaoning Telecom implemented the comprehensive coverage of e-Surfing 4G+ networks. It has been gradually adopting C-RAN architecture to cope with difficulties in site acquisition and energy consumption. However, because C-RAN network architecture consumes a large amount of fiber resources at the access layer, there will be a severe shortage of fiber resources in the coming 5G era due to the requirement of denser site deployment. Liaoning Telecom is in urgent need of a new solution that will allow it to conserve fiber resources and quickly improve wireless network coverage.
As the sub-solution of the X-Haul solution, Blade OTN is fronthaul-oriented and can effectively meet Liaoning Telecom's network deployment requirements. Blade OTN uses Huawei's Turbo WDM Technology to achieve the industry's largest 100G bandwidth using 10G optical components. It supports a maximum of 15 channels of Common Public Radio Interface (CPRI, as C-RAN fronthaul interface) access, and implements aggregation of multiple service channels at the lowest total cost of ownership (TCO), helping Liaoning Telecom reduce core fiber requirements by over 90%.
The optimal intelligent design of this solution eliminates wavelength planning, automatically provisions services upon power-on, and remotely locates faults, meeting the rapid network deployment and automatic O&M requirements of C-RAN fronthaul networks. Line-side 1+1 and ring network protections are configured to improve the reliability of C-RAN fronthaul networks. In addition, cascading ensures the smooth network evolution towards 5G fronthaul networks, and protects live-network investments.
To promote the development of the UBB industry and explore ways to boost service growth, Ultra-Broadband Forum (UBBF) 2017, will be held from October 18 to October 19, 2017 in Hangzhou, China. This UBBF will focus on the topics of ‘New Growth with B2B’, ‘Deliver the Video Dividends’, ‘Accelerate Gigaband Society’, ‘Towards 5G Era’, and on the innovation of All-Cloud Network solutions. Huawei will comprehensively demonstrate how X-Haul will help operators keep up with service requirements in the 5G era, promoting the full deployment of 5G bearer networks.
