The large bandwidth, low latency, and weak coverage of Mmwave determine that it is mainly suitable for three types of scenarios:
Mmwave is a hotspot coverage area for dense crowds with large business traffic. For example, transportation hubs such as stations and airports, stadiums, shopping malls, theaters and other crowded areas. These areas have a large number of terminals and large traffic demand. With the deployment of Mmwaves, a high-throughput layer of the network can be formed and the upper limit of network capacity can be increased. And especially VR/AR is worth mentioning. This type of scenario currently has a high demand for bandwidth, especially in the multi-terminal scenario. Taking 8K VR as an example, 50 devices, with about 5Gbps, need Mmwaves to meet.
Mmwaves are industrial Internet scenarios such as smart parks, smart factories, smart hospitals, smart schools, and smart docks. 5G empowers hundreds of industries and leads the digital transformation of all industries. In addition to large bandwidth, industry scenarios often have low latency and high reliability requirements, that is, 5G URLLC scenarios.
Taking intelligent manufacturing as an example, the operation of robotic arms and other equipment and the work of high-precision detection equipment all have high requirements for delay. With the help of the large bandwidth and low delay of Mmwaves, it is supplemented by MEC edge computing and AI technology to meet the needs of the scene well and achieve 5G landing.
The current optical fiber infrastructure is relatively complete, so broadband access is basically based on optical fiber. In fact, it is very simple, it is to use Mmwave to do the last mile access. The 5G signal is transmitted to the user's home CPE device through Mmwaves, and then converted into a Wi-Fi or wired signal, allowing users to achieve broadband Internet access.
