Patent ID: 7231451

Claim:
A transmit-only apparatus comprising: a protocol stack compatible with a protocol standard for local wireless communication, the protocol stack comprising selected portions of the protocol standard used for transmitting data; and a transceiver communicatively coupled to said protocol stack, wherein: the transceiver is operable to wirelessly transmit to a second apparatus a synchronization packet at a radio frequency within a predetermined frequency band, the synchronization packet usable to synchronize data transmissions; the transceiver is operable to wirelessly transmit to the second apparatus a first data packet at a radio frequency within the predetermined frequency band, wherein: the first data packet is associated with a first priority level; and the first data packet is transmitted after the synchronization packet by a first predetermined offset corresponding to the first priority level; the transceiver is operable to wirelessly transmit to the second apparatus a second data packet at a radio frequency within the predetermined frequency band, wherein: the second data packet is associated with a second priority level; and the second data packet is transmitted after the synchronization packet by a second predetermined offset corresponding to the second priority level; and the first and second predetermined offsets are usable by the second apparatus to determine the respective priority levels of the respective data packets.
