5G network is the fifth generation mobile communication network. Compared with 4G network, 5G network can increase data traffic density by 1,000 times, increase the number of device connections by 10-100 times, increase user experience speed by 10-100 times, and reduce end-to-end delay by 5 times. It can provide wireless network users with 1-20Gbps extreme experience rate, millisecond ultra-low-end end-to-end delay, and one million connection density and tens of Tbps traffic density per square kilometer. 5G network has the characteristics of large bandwidth, low delay, mass connection and low power consumption, so that the communication between people begins to shift to the communication between people and things, and even the communication between machines, thus bringing revolutionary impact on social economy and life. As of November 2018, 182 operators around the world have conducted 5G trials, deployments and investments in 78 countries. China has announced it will start 5G trial commercial use in 2019 and achieve 5G commercial use in 2020. 5G network sustains the future hope of the whole mobile Internet industry chain, which can deeply empower the security industry and meet the needs of the security industry.
5G large bandwidth capability and support for security services
In recent years, with the maturity of cutting-edge technologies such as big data and AI, security services have gradually improved their requirements for video clarity. Security cameras have developed from standard DEFINITION cameras at the beginning to quasi-hd 720P and HD 1080P cameras, and now 4K and 8K ultra-hd cameras. With the improvement of video definition, video transmission requires more and more network bandwidth. For example, for a single channel 4K video with 4096*2160 resolution and H.265 video encoding, the bandwidth rate is required to be 10-20Mbps, while for a single channel 8K video with 8192*4320 resolution and H.265 video encoding, Its bandwidth rate requirement is about 40-60Mbps. For some AR, VR, ultra HD video and other new mobile services, 4G network can no longer meet the demand, and the large bandwidth capacity of 5G network will be able to provide more high-definition monitoring data at a faster speed, and the higher definition of the picture and richer video details will make the video monitoring analysis value higher.
5G provides high reliability, low latency and support for security services
5G network has millisecond delay, which means faster response speed, which is of great significance for VR/AR security, mobile inspection, emergency response and other scenarios. Through millisecond low delay 5G network, remote agile control of UAV/robot can be realized and inspection tasks can be efficiently completed. For VR/AR scenes, VR/AR products often cause vertigo to the experience, which is due to the delay to a certain extent, and the low delay feature of 5G can effectively solve this problem. To achieve 5G low delay, on the one hand, air-port transmission delay should be greatly reduced; on the other hand, forwarding nodes should be reduced as much as possible and the distance between source and destination nodes should be shortened. For example, in terms of network architecture, Key technologies such as SDN and NFV, network slicing, core network function sinking and moving edge computing (MEC) are adopted to reduce latency.
5G mass connection capability and support for security services
The number of wide area IoT devices is expected to reach 4.1 billion by 2023, while the number of connected IoT devices in short range will reach 15.7 billion. The massive machine communication (mMTC) feature of 5G will bring massive device connections, further expand the scope of security monitoring, and enrich the acquisition of monitoring data, which will provide more extensive and multidimensional reference data for intelligent security cloud decision center
So as to make more comprehensive analysis and judgment, and make more effective safety precautions. The mass connectivity features of 5G will be of great significance in terms of equipment condition monitoring, asset tracking, and iot and inventory monitoring.
