How many Wi-Fi security sensors should you install?

If you are planning to deploy a Wi-Fi intrusion detection/prevention system, how do you know where to place your sensors and how many of them to install? Sensors, of course, are the distributed wireless devices that continually scan all Wi-Fi channels. They are looking for unauthorized devices that might be connected to your network, exposing it to denial-of-service attacks and malicious hacking. So do you just toss a few sensors up in the ceiling, cross your fingers, and hope for the best? That’s one approach.
