A network device includes a scheduler and a transmitter. The scheduler creates a media access plan (MAP) that has overlapping transmission opportunities and the transmitter transmits the MAP. Another network device includes a carrier sensor and a transmitter. The carrier sensor senses the availability of a network medium for transmission and the transmitter transmits data of a service during an allotted overlapping transmission opportunity if the carrier sensor indicates that the network medium is available. In another embodiment, the network device includes a unit which receives QoS parameters of at least one transmitted service from a QoS parameter determiner and a scheduler. The scheduler creates a MAP for a plurality of services to be transmitted, the scheduler defining the transmission opportunities based on their QoS parameters as received from either the parameter unit or applications providing the services. |
