看看

tiantiangege 发表于 2007-12-7 22:16

我想请问楼主,通过增加AP来实现覆盖范围的扩大,为什么一定要设成中继模式呢?难道不可以把相邻的AP设置成不同的频点吗?还有请教一下用你这种方法的话, 除了中心AP外,其他AP的频点如何设置??

AP1所处位置的接入点覆盖能解决吗？

jmj10101 发表于 2008-10-14 13:42

每中繼一次'帶寬就減少一半'
多中繼幾次'就只剩下不到2Mbps帶寬

你可到本站 http://forum.anywlan.com/viewthread.php?tid=11552&extra=page%3D6
看看更先進的跳台技術

有大功率中继没？
