On the eve of the 2023 Spring Festival, the China Academy of Information and Communications Technology released the "Statistical Bulletin of the Communication Industry in 2022", which shows that my country's 5G mobile network construction is the world's leading, and the total number of 5G base stations accounts for more than 60% of the world, and it continues to expand to more vertical fields. application. In the context of the continuous expansion of 5G communication infrastructure construction and application scenarios, coupled with the limitations of 4G network resources, high-definition video uplink transmission applications that have a strong demand for "wide connectivity" and "high uplink" increasingly require 5G technology to enable . The high-bandwidth, low-latency, and highly reliable 5G technology provides a strong communication guarantee for high-definition video transmission, and can achieve stable return of up to 8K video signals. High-definition video transmission applications covering IPC monitoring, drones, webcasting and other fields can achieve high-speed and mobile video transmission, which is inseparable from the efficient support of 5G modules.
In the field of live video broadcasting, live broadcast backhaul requires an uplink transmission bandwidth of up to 40-80 Mbps. 5G networks can provide stable real-time transmission capabilities for ultra-high-definition videos. UHD video transmission requirements.
The video resolutions of different terminals have different requirements on the rate
In various large-scale live broadcast applications, the original video stream collected by the camera enters the encoding and streaming device such as the live broadcast backpack, and after encoding, it is converted into an IP data stream, and the video data is forwarded to the 5G base station through the built-in 5G module. The 5G base station transmits video data to the broadcast guide vehicle through the core network, and then transmits the video data to the TV station video server through satellite or microwave, conducts broadcast guide editing, storage, and sends it to the video display terminal in various ways. The original video stream collected by the camera can also be encoded by streaming equipment such as a live backpack, and then converted into an IP data stream, and the video data is forwarded to the 5G base station through the built-in 5G module, and the 5G base station directly transmits the video data through the core network. To the video server of the TV station, guide, edit, store, and send it to the video display terminal in various ways.
In the field of industrial inspections, AI inspections through drones and 5G video transmission can shorten the manual inspections that lasted more than ten days to a few hours, and at the same time avoid the safety risks caused by inspection personnel working at heights . The definition of picture and video transmission supported by the 4G network is obviously insufficient, but the 5G network can achieve an uplink single user experience rate of more than 100Mbps, lower air interface delay, and better inspection effect.
巡检无人机可与高清相机、红外相机、夜视相机、激光雷达等多种传感器进行组合，传感器通过搭载5G模组将巡检视频通过上行链路传输到服务器，工作人员再通过平台进行观看，实现工业巡检高清视频即拍即传即看。
在安防监控领域，5G安防监控设备可摆脱有线部署的束缚，随需布置视频监控节点。5G提升上行带宽，支撑更精细化的视频内容识别与传输。搭载了5G模组的安防监控设备，如摄像头、工业相机、机器视觉设备等，可将作业现场画面传输至云平台，从而进行视频AI分析。
以当前典型垂直行业应用为例，在智慧矿山场景中，井下巡检、综采面和掘进面无人操作、开采现场均需采用超大上行5G专网对超高清视频进行无线回传；在应急通信救援领域，利用5G网络的大带宽传输能力，通过机载摄像头实时拍摄并回传现场高清视频画面，结合边缘计算能力与AI技术，实现快速的人员识别及周边环境分析，便于救援人员针对性地开展营救工作。
高清视频在垂直行业的数字化转型中应用广泛，但各行各业的差异性决定了其对网络的需求存在较大差异。5G上行速率较4G有明显提升，已从Mbps迈向Gbps，可大大满足各类终端对高清视频上传的速率要求。广和通5G模组全面赋能垂直行业，加速推进企业自动化、信息化与数字化，为行业应用提供超大带宽、超低时延和超高可靠性的保障。
