Farpoint Group has been performing detailed studies of the effects of interference on Wi-Fi-based Wireless LANs (WLANs) for much of the past year. The focus has been on exploring the nature of interference from a variety of angles, and a variety of traffic types, including general traffic, streaming video over Wi-Fi, and Voice over IP over Wi-Fi (VoFi). Overall, it is observed that interference from common radio-based devices, including microwave ovens, cordless phones, and even other wireless LANs, can have significant and indeed devastating impact on WLAN traffic of all types. The paper also explores techniques for evaluating interference in production environments, most importantly the new class of Spectrum Assurance (SA) tools that bring the power of expensive spectrum analyzers to cost-effective and WLAN-oriented products.
