- BE is an exponential value for backoff, which represents a range for backoff selection.
- Each device first waits for a randomly selected slot if it wants to transmit a frame during a Content Access Access Period (CAP). If the channel is busy, the device selects another random backoff value and waits for that time. If the channel is idle, the device wishing to transmit may transmit on the next backoff slot boundary.
