在高话务地区,写字楼里“小灵通”室内分布系统基站容易发生再建链请求率高。分析其原因,提出了设置“侦查天线”的方案,不用分配新频点就能躲避干扰,实践证明可以降低再建链请求率;提出了估测室内场强的公式,与实际误差一般小于10dB,在它指导下经过实验改善了系统性能。
In high traffic area, the office building “PHS ” indoor distribution system base station prone to re-build chain request rate. Analyze the reason, put forward the scheme that set up “the investigation aerial”, can avoid the interference without assigning the new frequency point, the practice proved that can reduce the request rate of chain building again; Proposes the formula to estimate indoor field strength, and the actual error is generally smaller than 10dB, under its guidance to improve the system performance through experiments.
