The principle of ultra dense networ

The principle of ultra dense networking technology is to improve spectrum bandwidth and spectrum utilization by increasing the deployment density of equipment in the regionThe ultimate purpose is to ensure that the future mobile network can fully meet the needs of users for ultra-high data traffic and ultra-high experience rate. The implementation strategy is to improve the frequency reuse by deploying a large number of flying cells with a coverage radius of 20m and leather cells with a coverage radius of 100m. This method can effectively shorten the distance of information and data transmission, and the shortening of transmission distance can also effectively reduce the loss caused by the transmission process and the power consumption of communication tools, but the interference problem needs to be considered [2]. The interference problem faced by this technology is caused by the excessive density of wireless access stations, which will lead to high density of wireless access stationsCause serious interference problems, and even reduce the spectral efficiency of the system to a certain extent. on the other hand,In order to effectively meet the requirements of high throughput and user experience rate in the hot spot area, a large number of spectrum resources need to be introduced and builtSet up wireless access points with sufficient density, which means that the cost of system deployment will increase greatly, and it will also lead to energy consumption
