摘要:
A system for optimizing the operation of a plurality of radio modules incorporated within a wireless communication device (WCD) connected as a slave on a low-power wireless network, wherein a low-power device is acting as the master of the wireless network. The timing of communication between master and slave may be established by the master, and as a result, the WCD may utilize a control strategy to allow substantially concurrent active communication in one or more of the plurality of radio modules while still operating under the parameters set forth by the low-power master device.
摘要:
A system for managing the operation of a plurality of radio modems contained within the same WCD. One or more of the plurality of radio modems may be a dual-mode radio modem enabled to communicate using at least two separate radio protocols concurrently. The operation of the one or more dual-mode modems may be managed by resources encompassed in a radio modem interface coupled to, or integrated within, the dual-mode radio modem. These management resources may receive information from the operating system level of the WCD and from the at least two radio modem stacks utilizing the resources of the dual mode radio modem in order to coordinate the operation of the at least two radio protocols concurrently active in the modem.
摘要:
A communication device including a receiver for receiving information via a first radio protocol directly from a first communication device concerning at least a second radio protocol; and a controller for controlling communication of the communication device in dependence upon the received information.
摘要:
A plurality of polling response transmission times are allocated for a corresponding plurality of remote devices. The remote devices operate according to a first wireless transmission mode, such as Bluetooth LEE. These allocated polling response transmission times are outside of a time interval designated for communications according to a second wireless transmission mode, such as Bluetooth. Each of the polling response transmission times may be offset from a polling packet transmission time by a corresponding delay interval. In addition, a polling packet to the plurality of remote devices is transmitted, and one or more responses to the polling packet are received. Each of these responses is sent by one of the remote devices during its corresponding polling response transmission time. In addition, communications according to the second wireless transmission mode may be conducted during the designated time interval.
摘要:
A lightning detector for lightning detection and a lightning detection method, wherein the lightning detector uses at least two separate channels or frequency bands for lightning detection, and wherein the lightning detector is a mobile RF device provided with radio interfaces for at least two communication channels or frequency bands, whereby at least one of which is normally a telecom channel/frequency range and wherein these channels/ranges are used in lightning detection.
摘要:
A device participates in a wireless communications network having a coordinator device that is responsible for allocating resources in the wireless communications network. Further, the device establishes a peer-to-peer connection with a remote device in the wireless communications network. This peer-to-peer connection is based on a reservation of resources from the coordinator device, wherein the reservation has one or more timing parameters. Upon detecting a disappearance of the coordinator device from the wireless communications network, communications with the remote device continues according to the one or more timing parameters of the peer-to-peer connection.
摘要:
A first device participates in a wireless communications network having a transmission medium designated for exchanging wireless signals in a first format that is associated with the wireless communications network. A portion of the transmission medium is reserved for the transmission of signals in a second format, which may be incompatible with the first format. Accordingly, one or more signals of the second format are transmitted to a remote wireless communications device. These one or more signals of the second format facilitate the remote wireless communications device's participation in the wireless communications network. Accordingly, the remote wireless communications device may be awakened from a sleep state or a hibernation state.
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:
A wireless communications device includes a first receiver and a second receiver. The first receiver is configured to receive a first wireless signal (such as a Bluetooth or WLAN signal), while the second receiver is configured to receive a second wireless signal (such as a UWB signal). In addition, the second receiver is configured to determine spectral characteristics of the first wireless signal. Based on these determined spectral characteristics, an interference detection module may identify interference in the first wireless signal.
摘要:
A method for use by a device communicating according to a short-range wireless connectivity protocol in attempting to establish a connection to another device using an enhanced inquiry and/or paging procedure as part of the connection procedure, the method including a step in which the device transmits a first packet for establishing a connection to the other device, and the other device responds with one or more response packets whose content depends on whether the other device is configured to perform the enhanced procedure. In some embodiments, the first packet is an identifier packet including extension data indicating via a predetermined bit pattern that the device is itself configured to perform the enhanced procedure.
