摘要： A communication access protocol improves the accessibility of devices operating on an asynchronous network (100), while supporting reduced power consumption. The network (100) includes a mediation device (130) for facilitating communications among network devices. Generally, each network device periodically transmits beacon signals to advertise its presence, and listens for communication signals targeted at the network device (532, 534). A device initiating communication with another operates in one of at least two operating modes in order to establish communications (536, 537, 538). In one mode, the initiating device communicates with the mediation device in order to derive timing information for the other device (537). In another mode, the initiating device listens to receive beacon signals directly from the target device in order to synchronize communications with the device (538). The selection of one of the two operating modes depends on a control parameter established for the initiating device, which in one embodiment is dependent on the urgency of communication, a maximum number of retries for using the mediation device, or the like.

摘要： The disclosure is a routing method for data in a personal area network. The personal area network includes a plurality of nodes. The method includes receiving a frame at a node, determining whether the node contains a routing table entry for the frame destination, and when the node contains a routing table entry, determining a route for the frame based on a first routing protocol. The method further includes, when the node does not contain a routing table entry for the frame destination, determining whether a route should be discovered for the frame destination, and when a route should not be discovered, determining a route for the frame based on a second routing protocol.

摘要： A beacon assisted asynchronous method of wireless communication according to the present invention enables initiating and target devices (12, 14) to remain in sleep mode most of the time and to periodically wake up to asynchronously, and directly, communicate with one another. Specifically, each of the initiating and target devices (12, 14) transmits a beacon while operating in a default transmit/receive mode (40, 40a, 42, 42a) and subsequently listens for a response. Alternatively, the initiating device (12) may enter a data packet message mode to receive a beacon from the target device (14) and to subsequently transmit a data packet message to the target device (14) after receiving the first beacon. The initiating device (12) minimizes the length of time in which it must wait to receive the target device beacon by timing a corresponding target beacon receive period based on stored data such as information based on previous communication with the target device (14).

摘要： A method is provided for estimating relative location information for wireless devices. Individual estimates are obtained from two or more alternative means that determining the relative location, such as range information, of first and second wireless devices with respect to each other (710, 720, 910, 920). At least one of these estimates involves an estimate of relative location between one of the first and second devices and a third device. These estimates are combined to provide a new estimate that is statistically more accurate than any one of the individual estimates (740, 940).

摘要： A contention resolution method includes the steps of determining a contention has occurred and requesting contention resolution from radios in the system (604). Radios in the system receive the request and do not transmit in the next control frame (606). Group leader radios (202, 208 and 214) transmit the identification code they were able to demodulate in the previous frame to the master radio (608). The master radio (212) receives the information from the group leaders and transmits a control-channel access message to one of the contending radios (610).

摘要： A subscriber unit automatically selects repeater access mode, if a repeater is available, or talk-around mode, if a repeater is not available (500). The subscriber unit initiates a call by transmitting a call setup request on the outbound channel used by the repeater (510), and by monitoring the outbound channel to detect a response from the repeater (520). If a response is received within a timeout period, the subscriber unit continues the call by transmitting on the inbound channel (530, 540). Otherwise, the subscriber unit continues the call using talk-around mode, by transmitting on the outbound channel (530, 550). In this process, the repeater monitors the outbound channel to determine when a call setup request is transmitted by the subscriber unit (610), and responds accordingly on the outbound channel (620, 630), thereby indicating its availability. The repeater then monitors the inbound channel and retransmits, or repeats, signals received via the inbound channel, on the outbound channel (640, 650, 660).
