TD-LTE高速铁路规划方案研究

伴随着电子商务及互联网的飞速发展,移动终端用户对数据传输速率的需要日趋强烈。4G时代的到来,使得高铁移动终端用户可以有良好的体验。但由于高铁的高速移动性以及高铁本身的结构特性,在LTE高铁网络规划建设中会遇到多普勒效应、车体高穿损、小区间切换困难等诸多难题。对以上问题做了相应的研究,并结合某市LTE高铁建设,提出了具体的解决方案。

A study on planning TD-LTE high-speed rail

With the rapid development of e-commerce and internet, the need of high speed data’s transmmison increases strongly and the mobile terminal users on high-speed rail could have good experience with the arrival of the 4G era. Because of the structure characteristics and high speed mobility of high-speed rail, there are some difficult problems in the planning of TD-LTE high-speed rail such as the Doppler effect, the loss of penetration, the switch between cells and so on. This paper does some research on the problems above and put forward specific solutions combined with construction of a city’s TD-LTE high-speed rail.
