摘要
随着高铁大建设,提高高铁无线网络覆盖是运营商目前面临的主要任务之一。因高铁沿线地形环境复杂,基站建设遇到市电引入难、市电引入费用过高以及后期维护困难等问题。文章通过对直流远供系统的分析,结合实际工程,探讨直流远供在高铁场景下的应用。
With the constrction of the high-speed railway, improving wireless network coverage for high speed railway is one of the main tasks for operator currently. As the complex terrain environment along the high speed railway, the base station construction encountered issues., the difficult to introduce mains, and the high cost of introduction mains and later maintenance difficults. This article analyzed the DC remote supply system, discussed the application of DC remote supply in the high-speed railway combined with actual project.
