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."
