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.
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 (326) 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 (336) 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 (326) 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 (336) 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.

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.
Abstract:
A method is provided for a remote device to monitor and communicate with a wireless network using cyclic beacons. The remote device receives a beacon (1405), which beacon includes beacon information that defines a superframe. From the beacon information, the remote device determines whether the received beacon and the associated superframe are assigned to a network device or are unassigned (1410). By receiving as many beacons as there are allowable devices in the network, the remote device can determine if the network is full (1430). If the remote device runs through all of the beacons and all indicate that their associated superframes are assigned, then the remote device determines that the network is full and performs a network-full function. If the remote device receives a beacon that indicates that its associated superframe is unassigned, it determines that the network is not full and performs an association request during the unassigned superframe (1415).
