Selected Answers: D
Channel utilization is the primary indicator of capacity around an interface. When enabled, the AP is
constantly monitoring the amount of wireless traffic it can decode in the channel, and providing a measure. It
is not only accounting for traffic transmitted by its own clients, but it is also is accounting for other wireless
traffic on the channel, which could be coming from neighboring APs and wireless clients not associated with
your wireless network. The neighboring APs and wireless clients still use capacity, and your network cannot
transmit data while those other transmissions are occurring.
The higher the channel utilization, which is measured in percent, the less the spare airtime that is available.
Channel utilization is the most important indicator of wireless capacity.
High channel utilization is usually caused by a high number of station connections, but can also be caused by
a smaller number of stations transmitting a large amount of traffic. It does not matter if the stations and APs
are your own or if they are neighboring devices
