Overview
Miercom was engaged to validate Cisco CleanAir technology for interference classification,
mitigation and avoidance, and to compare it with products from other vendors. The most up-to-
date versions of wireless controllers and access points from Cisco, Aruba, Motorola, Trapeze,
HP, and Meru were compared in terms of their respective performance for this evaluation.
We tested the impact of interference on throughput from a variety of non-Wi-Fi devices,
including continuous wave type signals from video surveillance cameras, frequency hopping
2.4GHz and 5GHz phones and Bluetooth devices, and cyclic type from microwave ovens. The
evaluation included the ability to detect and classify each type of interference from single
sources and the ability to accurately classify multiple sources of interference. We also looked at
the self-healing properties, i.e. the ability to identify major sources of interference, and switch to
another channel to avoid them. Also included in the tests was examining the ability to detect an
off-frequency rogue access point, hiding between standard Wi-Fi channels, that could provide
backdoor access to the wired network.
