    摘要: The present invention provides techniques for responding to overlapping conditions in wireless communications networks include receiving data transmissions from a transmitting device across a wireless communications network. These data transmissions correspond to a connection with the transmitting device and occur within a reserved portion of a communications resource. An interference condition is detected that includes an allocation of the communications resource for a neighboring device that overlaps with the reserved portion. Based on this detection, the method sends a notification to the transmitting device, the notification indicating the presence of overlapping transmissions in the reserved portion of the communications resource.

    摘要: Multiple nodes communicate using repeating patterns of superframes, where each of the superframes includes a beacon period. A beacon slot in a first Media Access Slot (MAS) is reserved by the plurality of nodes. This reserved slot occurs in the beginning of the beacon period and is used for communicating information relating to the superframe configuration. This information may involve adjustments to the number of MASs reserved for beaconing.

    摘要: One or more electromagnetic energy measurements are generated. Each of these measurements corresponds to an available communications bandwidth for a communications device and indicates a frequency of a radio frequency (RF) signal source. From these measurement(s), one or more interference sources are identified. These measurements may include a series of electromagnetic energy measurements over a predetermined time period. An interference source may be identified when each measurement in the series of electromagnetic energy measurements indicates an RF energy source at the same frequency. Each of these measurements may be stored. In addition, statistics regarding these measurements may be generated.

    摘要: Ultra wideband (UWB) techniques are applied to radio frequency identification (RFID). For instance, a reader generates a UWB IR interrogation signal, and receives a UWB IR reply signal from an RFID tag in response to the interrogation signal. In addition, the reader may generate from the UWB IR reply signal a baseband response sequence. This sequence includes at least a tag identifier. A reader may store at least a tag identifier. Upon receipt of a UWB IR interrogation signal, the tag obtains a plurality of clock pulses from the UWB IR interrogation signal. Based on the plurality of clock pulses, the reader transmits at least the tag identifier in a UWB IR response signal.

    摘要: The present invention provides techniques for spatial reuse in wireless communications networks. Accordingly, the present invention provides A device participates in a wireless communications network. The network has a shared transmission medium for the exchange of communications traffic. Further, the device determines a value for at least one interference condition in the shared transmission medium of the wireless communications network. Based on this value, a planned transmission to a remote wireless communications device is scheduled. For instance, when this value is less than a predetermined threshold, this scheduling employs a time-overlapping access technique.

    摘要: The present invention relates to systems and methods for a implementing an optimized low-end radio communication protocol, wherein the communication link is flexible and the power consumption characteristics are optimized. One facet of the system's flexibility relates to the system's ability to negotiate device control roles associated with a polling communication link. Also, once the device control roles are in place and the communication link is established, the system selectively implements a number of polling protocols for a multitude of applications that need a low power consumption. In some embodiments the system maintains a communication link with a reduced frequency polling protocol. This type of communication link maintains efficient power consumption characteristics, as well as, connection times that are faster than establishing a communication link between disconnected devices.
