The Invisible Threat: Interference and Wireless LANs

---

I nterference is a fact of life in the unlicensed bands used by wireless LANs (WLANs), and is an increasing challenge in all WLAN environments – the enterprise, outdoors (including metro-scale Wi-Fi meshes), and in the residence. As the number of unli- censed devices grows and as ever more mission-critical applications are deployed on WLANs, interference represents a challenge that must be addressed.
Farpoint Group has been studying the impact of interference on wireless LANs, and we have empirically measured the result in a variety of situations. We have learned that many forms of interference can have a detrimental and even destructive impact on WLAN traffic, degrad- ing data both throughput and time-bounded traffic typified by voice and video. In addition, we have analyzed the impact of a variety of interferers often seen in the enterprise and have evaluated their effects on performance. The results of this work will shortly be published in a series of Farpoint Group Technical Notes.
