发展异构网以满足LTE网络覆盖及容量需求的研究
|
摘要
分析当前三大运营商的LTE网络覆盖发现,传统的宏基站建设由于频率与站址的影响,无法在城市中进行深度覆盖。在LTE异构网设备不断成熟的情况下,需要在城区、城中村及住宅小区中进行运用。随着智能终端的发展,移动宽带业务不断增长,因此电信运营商也将3G网络升级为速率更高的4G网络。当前的4G LTE网络建设会受到站址资源与频率资源的双重压力,所以主要分析了发展异构网以满足LTE网络覆盖以及容量需求的方法。
From the current LTE network coverage of the three major operators,the traditional macro base station construction can not provide deep coverage in the city due to the influence of frequency and site. In the case of LTE heterogeneous network equipment maturing,it needs to be used in urban areas,urban villages and residential areas. With the development of smart terminals,mobile broadband services continue to grow. For this reason,telecom operators will upgrade the 3G network to a faster 4G network.The current 4G LTE network construction will be under the dual pressure of site resources and frequency resources. Therefore,the development of heterogeneous networks to meet the LTE network coverage and capacity requirements is mainly analyzed.
