1. Challenges from business requirements Traditional mobile communication networks are dominated by voice and data services, and 5G The types of mobile communication services in the era are more diversified. Various typical services in the 5G era pose challenges to the network from multiple dimensions, such as: a. High Speed 5G new services represented by virtual reality and high-definition video services have brought unprecedented challenges to network bandwidth. The traffic consumed by a single wireless connection has increased significantly, reaching the requirement of a per capita connection rate of 100Mbps. b. High Flexibility 5G services in hotspot areas have large changes in the demand for network resources, and higher requirements for dynamic network expansion and intelligent adaptation. c. Massive Connectivity In the 5G era, the popularization of mobile connection services represented by the Internet of Things brings massive wireless connections and high-density network topology distribution, which brings great challenges to the anti-interference and operation and maintenance of the network. d. Latency Sensitive In the 5G era, low-latency services represented by tactile Internet, telemedicine, and intelligent manufacturing pose unprecedented challenges to network transmission latency. The transmission delay in the extreme case is less than 1ms, which is one percent of the current 4G network transmission delay. Architectural changes to meet the corresponding needs. e. High reliability Some high-speed mobile services face great challenges in meeting high communication reliability under the characteristics of 5G single-station short-distance communication radius. f. Openness The expansion of 5G services to the public domain and vertical industries requires that the 5G network must be an open network, and technologies such as network slicing are required to meet the diverse needs of 5G services. fiber optic cable spliter fiber optic cable spliter fiber optic cable spliter
Compared with the current 2G/3G/4G mobile networks, 5G mobile networks will be deployed on higher C-Band and millimeter-wave frequency bands to meet the requirements of 5G services for ultra-large spectrum bandwidth. Compared with the sub-3GHz frequency band in the 4G era, the 5G macro base station signal deployed in the high frequency band faces greater link loss when covering indoor scenes through walls. Compared with the sub-3GHz band 4G macro base station signal, when the C-Band band outdoor signal penetrates a concrete wall, it will generate an additional 8-13dB link loss for each wall penetrated. The huge attenuation caused by the 5G signal in the higher millimeter-wave band causes it to basically lose its ability to penetrate walls. The loss of millimeter-wave signals penetrating concrete walls exceeds 60dB. It will be very difficult for the outdoor 5G macro base station signal to enter the indoor coverage, and it is necessary to cooperate with the construction of a dedicated indoor distribution network indoors to provide the highest quality indoor scene 5G services. Therefore, the 5G indoor distribution network in indoor scenarios needs to be deployed at the same time as the outdoor 5G network to ensure the consistency of indoor and outdoor experience for mobile users. fiber optic cable spliter fiber optic cable spliter fiber optic cable spliter
