The Influence Of Network Density And Backhaul Mode For Wireless Backhaul System

As developed,4G technology has made great progress in the business use. However, with the popularity of intelligent terminals, data traffic will show a growth spurt. At the same time, with the way of.life being plentiful, the communication mode is also more diversified."Communication between people" is no longer meeting the needs of the society. Finding the way to solve the problem of "communication between people and things" and "communication between things and things" becomes more important. And establish the network which seems using low power consumption, much safer and can cover everywhere. So in the future, wireless network will develop in the direction of being diversified, intelligent, and broadband. While the distribution of the major data services is more concentrated in the indoor or hot spot area.In view of this, research on the key technology of next generation mobile communication will mainly focus on the data demand and changes in demand patterns. This presents a huge challenge to the load capacity of wireless backhaul network and mobile network deployment. At the same time, increasing shortage of spectrum resources has also brought great resistance to the development of mobile network. Super dense network is one of the key technologies of the communication network in the future and is an effective mean to solve the problem of heterogeneous network coverage and capacity problems. The solution for the load ability of wireless backhaul network is always under research, and there has been made some progress.This paper is based on the MATLAB simulation platform of LTE, and mainly discusses on the backhaul mode of wireless backhaul network and dense network deployment. The main contributions include:(1) According to the method and scene hypothesis of system level simulation by3GPP proposal and with the simulation parameters requirements of3GPP, I maintain the LTE system level simulation platform.(2) For the backhaul network architecture and mode in simulation platform, I add a kind of backhaul mode that can use spectrumresources effectively, and improve the simulation function module and data processing module.(3) For the research on the key technology of dense network, simulate indoor and hot spot area in heterogeneous work. Watch the changing way of network performance and give the reasonable suggestions of network deployment. (4) For the new mode of backhaul, by comparing with the original backhaul mode, predicting the possibility of realization.
