IEEE 802．11b／g无线网络同／近频干扰研究

随着WLAN用户逐渐增多，网络速度经常不稳定，尤其是在进行大量的数据传输时。其主要原因，就是同近频干扰。我们将以IEEE 802．11b的产品作为研究对象，研究IEEE 802．11b协议相关内容。从原理上说，分离具体频段是相当重要的，频段分离得越开，效果会越好（例如1和11）。不过，依据实验测试，在1和6或者6和11这样的组合下效果已经相当好，分离得更开，效果提升已不太明显，且会导致频段资源的浪费和减少。

Study on Interference of IEEE 802.11b/g with the Same/Adjacent Channel under Aggressive Environment

With the ever increasing users of the WLAN, the speed of the network becomes unstable, especially when large amount of data are being transmitted. The most important reason for this unstableness is caused by same/contiguous frequency interference. In this article, using IEEE 802.11b, we make researches on the related content of IEEE 802.11b protocol. In principle, it＇s quite important to separate idiographie frequency band from each other. The more distinct the frequency band is separated, the better effect can be achieved （as shown in example 1 and 11）. Experimental tests have shown that the effect of the combination which consists of land 6 or of 6 and 11 is very good. However, the effect won＇t be further improved if the frequency is excessively separated, or the frequency band resources will be wasted and reduced.
