Which design practice is the best to reduce wireless CCI?
A.
Place adjacent access points on different channels.
B.
Place adjacent access points on the same channel.
C.
Eliminate all signal overlap between access points.
D.
Configure access points with the lowest supported data rate.
E.
Place adjacent access points on non-overlapping channels.
Explanation:
Co-channel interference: When access points, whose coverage area overlaps,, are configured in
the same channel or channels with overlapping frequencies, it causes connectivity issues for
clients in the overlapping coverage area. In order to avoid this issue, either change the channel
number to a non-overlapping channel, or move the access point farther away so that their
coverage areas do not overlap. For example, in 802.11b/g, network channels 1, 6, and 11 are nonoverlapping channels.
