Two or more WLANs that overlap coverage
zones (2 cells per network).
Interference can occur (shaded
regions). -- Solution is to configure each AP to operate at a different channel frequency (802.11b
channels 1, 6, 11 do not interfere even when cell overlaps). The wireless devices will acquire the
channel to use once associated to the AP. Interference can cause Denial of Service (DOS) due to
the electrical jamming effects.
