10. An apparatus comprising:
-
an external input port; processing circuitry coupled to the external input port, the processing circuitry to determine and process information to be transmitted on a radio channel prior to receiving an indication of availability of the radio channel; media access control circuitry to format the information according to a media access control protocol prior to receiving the indication of availability of the radio channel; and radio circuitry to prepare to send the information on the radio channel prior to receiving the indication of availability of the radio channel;
wherein the radio circuitry sends the information on the radio channel upon receipt of a trigger from the external input port, the trigger indicating the availability of the radio channel. - View Dependent Claims (11, 12, 13, 14, 15, 16)
