The coordinator and other nodes transceive a superframe during the beacon interval, in which the superframe begins with an active interval, which is immediately followed by an inactive interval, and in which the active interval begins with a contention free period, which is immediately followed by a contention access period, which is immediately followed by the inactive interval.
