Cognio on Interference, Part Deux
October 16, 2006

Wireless Weblog sponsor Cognio has released a new white paper by company CTO Neil Diener, entitled 'Twenty Myths of Wi-Fi Interference.'
It's an expansion of Diener's previous white paper — which was entitled, funnily enough, 'Ten Myths of Wi-Fi Interference' — and examines the challenges inherent in deploying and managing a Wi-Fi network. The ten "new" myths the white paper debunks are as follows:
- "Wi-Fi interference doesn't happen very often."
- "I should look for interference only after ruling out other problem sources."
- "There's nothing I can do about interference if I find it."
- "There are just a few easy-to-find devices that can interfere with my Wi-Fi."
- "When interference occurs, the impact on data is typically minor."
- "Voice data rates are low, so the impact of interference on VoWi-Fi should be minimal."
- "Interference is a performance problem, but not a security risk."
- "802.11n and antenna systems will work around any interference issues."
- "My site survey tool can be used to find interference problems."
- "RF analysis tools are too bulky and too expensive."
