Embodiments may define traffic priorities to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames, association response frames, reassociation response frames, and probe response frames with an access category for low power consumption stations or sensor stations comprising a parameter record defining a contention window that is the earliest contention window to open amongst contention windows defined for the access categories for traffic. In some embodiments, the MAC sublayer logic may store the parameter record sets for access categories in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive and detect communications with frames comprising the access categories and store a parameter set for one or more of the access categories in a management information base.
