Device Duty Cycle
The Device Duty Cycle Chart is a stacked bar chart that shows the duty cycle of eachdevic e type on a channel.The
duty cycle is the percentage of time each device type operates or transmits on t hat channel.Though Wi-Fi devices
do not transmit ift hereis another Wi-Fi or non-Wi-Fidevice acti veat that ti me,most non-Wi-Fi devices do not
follow sucha protocol for transmissions. Since t hese devices operate independentlyw ithout regardt o any other
devices operating on the same channel,the t otal duty cycle of all device types may add up to more than 100% on a
channel.For example, one or more video bridges may be active on a channel, each with 100% duty cycle. The same
channelmay have a cordless transmitter wit h 10% duty cycle and a microwave oven with 50 % duty cycle. In this
example,the Devic e Duty Cycle chart shows all three device types wit h their respective duty cycle percentages.
