  • Publication number: 20070100473
    Abstract: A transmitter (500) is provided for transmitting host data over a wireless channel. The transmitter (500) includes a free-running timer (560) that provides a series of increasing free-running timing values; a host interface circuit (510) that receives host data from a local host circuit and a first free-running timing value from the series of increasing free-running timing values; a detection circuit (530) for detecting a global synchronizing event and receiving a second free-running timing value from the series of increasing free-running timing values, and for placing the host data and the first free-running timing value into a host interface packet; and a wireless transceiver (530) for adding the second free-running timing value and an identifier for the global synchronizing event to the host interface packet to form an air link frame, and transmitting the air link frame over a wireless channel to a remote wireless device.

  • Publication number: 20060256818
    Abstract: A method (900) is provided for operating a transceiver that comprises: transmitting a preamble (905); transmitting an outer header (320) identifying parameters of an outer payload (340), after transmitting the preamble (910); and transmitting the outer payload after transmitting the outer header. The transmitting of the outer payload includes: transmitting an inner header (325) identifying parameters of an inner payload (345) (920); transmitting an inner payload after transmitting the inner header (930); and repeating the transmitting of the inner header and the transmitting of the inner payload a plurality of times. A corresponding method of operating a receiver functions by receiving each of these transmitted elements.

  • Publication number: 20060203795
    Abstract: A method is provided for transmitting data. A first device (121) generates a first signal (320) having a first duty cycle, comprising a first gated-on portion (323) and a first gated-off portion (363) in a time slot (260); and a second device (125) generates a second signal (330) having second duty cycle, comprising a second gated-on portion (333) and a second gated-off portion (363) in the same time slot (260). The first gated-on portion (323) is generated during a first segment of the time slot (260) and the first gated-off portion (363) is generated during a second segment of the time slot (260), while the second gated-on portion (333) is generated during the second segment and the second gated-off portion (363) is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots (250) and provide error correction, power control, and the like. A preamble (860) can be transmitted at an increased power level to facilitate acquisition.

  • Patent number: 6480977
    Abstract: A method is taught for monitoring information traffic through a traffic link transmitting first and second differing information signals each having a plurality of information layers and first and second pluralities of information packets in a monitoring system having monitoring circuitry and including processor circuitry and a server operating cooperatively with the monitor circuitry. The method includes segmenting the information packets of the first and second pluralities of information packets into information cells to provide corresponding first and second pluralities of information cells and interspersing the information cells of the first and second pluralities of information cells with each other to provide interspersed first and second information cells.
