Now that we have a basic understanding of 802.11 channels, let’s describe an
interesting (and not completely uncommon) situation—that of a WiFi jungle. A
WiFi jungle is any physical location where a wireless station receives a sufficiently
strong signal from two or more APs. For example, in many cafés in New York City,
a wireless station can pick up a signal from numerous nearby APs. One of the APs
might be managed by the café, while the other APs might be in residential apartments
near the café. Each of these APs would likely be located in a different IP subnet
and would have been independently assigned a channel.
