2.3 Channel Utilization

Channel Utilization is defined by the length of inter-packet gap. Channel utilization can be increased by decreasing the interpacket gap. Increasing the channel utilization also increases the transitions on I/O pins which increases power consumption.

See Appendix Section 6.4 for observing power consumption variations due to change in channel utilization.
