IoT is one of the main business applications of 5G. IoT business is widely used in warehouse management of smart logistics and industrial manufacturing of smart factories. fibconet.com fiber optic splitter terminal box
The logistics hub of smart logistics needs to use wireless networks to connect a large number of objects with electronic tags to achieve efficient management, scheduling and transshipment of materials. In the logistics hub, the objects in the three-dimensional shelves need to be identified, positioned and sorted, and the robot needs to be automatically transported to the predetermined position. The three-dimensional warehouse of the logistics hub has many kinds of objects and high density, and even one object per square meter on average. fibconet.com fiber optic splitter terminal box
In a smart factory, a large number of robots, manipulators, AGVs (Automated Guided Vehicles), production equipment, etc. generate a large amount of operating data, which need to be reliably transmitted to the management platform in real time through the network. There are many types and large numbers of connection objects, and each object needs a connection, and it is estimated that one connection per square meter will be reached. In general, in certain indoor scenarios, the 5G network is required to provide an average of one connection per square meter, which is equivalent to one million connections per square kilometer. Since various types of indoor 5G services will be carried by the same network using the “slicing method”, there are many factors that need to be considered in the network construction process, and the challenges faced are great. Under a certain wireless spectrum efficiency, the edge rate of 100Mbps needs to be for larger spectrum bandwidth, only high-frequency bands with more available spectrum resources (such as C-Band and millimeter-wave bands) can be used for networking; 1ms latency and 99.999% reliability requirements require network architecture redundancy and coverage redundancy; With a massive connection area per square meter, the capacity requirement changes with time, and the network needs to have flexible capacity expansion capabilities. In indoor scenarios where the traffic volume changes drastically and new services are activated locally, the network needs to support capacity flexibility and intelligent operation. From this it can be seen that building an indoor 5G network that meets the requirements of the above table will face challenges in high-frequency networking, network capacity elasticity, network reliability, network operation, maintenance and operation.fibconet.com fiber optic splitter terminal box
High-frequency networking has large propagation loss and penetration loss, and it is difficult to cover indoors outdoors.
ITU-R recommends using Sub 6G and microwave frequency bands to deploy 5G networks. Spectrum resources in high frequency bands can provide wider bandwidth. Sub 6G (such as 3.5GHz, 4.9GHz) and different frequency bands such as millimeter wave have different coverage capabilities. According to the law of radio wave propagation, the higher the frequency, the greater the air propagation loss, the greater the penetration loss of the wall or glass, and the more difficult it will be to cover indoors outdoors. fibconet.com fiber optic splitter terminal box
