In October 2018, Huawei Technologies Co., Ltd. (hereinafter referred to as Huawei) opened the world's first 3GPP-based 5G millimeter wave commercial first call. The success of the first commercial use of millimeter waves indicates that the 3GPP-based 5G millimeter wave network and related industry chains have matured, and the global 5G millimeter wave applications have begun to set sail.
Millimeter wave is a high-frequency new frequency band defined by 3GPP for 5G, with 28GHz as the mainstream frequency band. High-frequency millimeter waves have natural advantages such as large bandwidth and large capacity, and the user experience rate can reach more than 10Gbps. At this stage, based on the 3GPP R15 protocol, millimeter waves can be commonly used for personal mobile enhanced services (eMBB) in hot traffic areas, and enterprise and home broadband access (FWA). The coverage area of ​​the first call commercial scene includes two hot traffic areas and a hot traffic street, which is a typical 5G millimeter wave eMBB application at this stage-a patchy hot area and a street coverage scene.
This commercial solution is based on 5G millimeter wave 28GHz frequency band, 5G and 4G joint networking (NSA). Huawei provides the industry's largest millimeter-wave base station with transmit power (EIRP), using 4CC carrier aggregation technology, 200M per carrier, with a total bandwidth of 800M. After successfully opening up the commercial first call, Huawei will continue to verify the peak rate, delay, coverage and mobility of millimeter wave commercial networks.
After 3GPP R15 defined eMBB and FWA services, the millimeter wave industry chain was quickly matured. In terms of FWA, Huawei launched the first 3GPP millimeter wave-based 5G CPE chip-Balong 5G01 in early 2018, and took the lead in launching the industry's first millimeter wave 5G CPE; for eMBB, Huawei is also about to release the Kirin series of 5G chips that support millimeter waves. With 5G mobile phones. Millimeter wave technology as eMBB can enable mobile 8K/3D/360-degree panoramic ultra-high-definition video, VR/AR immersive user experience and other applications; as FWA, it can help operators with more flexible and economical investment than fixed network construction Mode, faster deployment of fiber-like home and enterprise broadband networks.
In 2019, R16 will also define more new millimeter wave applications: integrated access and backhaul (IAB), regional industry low-latency applications (uRLLC), etc. As the only manufacturer capable of providing end-to-end 5G full system (including core network, bearer, 5G access network, 5G CPE, chips) in the industry, Huawei will continue to provide comprehensive and leading high-frequency millimeter wave solutions, and global operations Together, expand the application boundary of 5G millimeter wave and open up a blue ocean of new 5G business.
