高层建筑的窗边由于无线传播环境较好,移动信号比较杂乱,容易产生导频污染,影响通话质量。虽可以通过优化邻区关系、调整室外宏站、增加室内分布天线等常规方法进行优化。但根据现场实际情况,采取分区异频的方法,充分利用信号覆盖与建筑构造的关联性,能更有效解决高层导频污染问题。
High-rise building windows due to better wireless communication environment, mobile signals more clutter, prone to pilot pollution, affecting call quality. Although it can be optimized by optimizing the neighbor relationship, adjusting outdoor macro stations and increasing indoor distribution antennas, conventional methods are available. However, according to the actual situation in the field, the method of zoning and inter-frequency is adopted to make full use of the correlation between signal coverage and building construction, which can more effectively solve the problem of high-level pilot pollution.
