  • Patent number: 11728862
    Abstract: A communication system that includes a management server communicatively coupled to a gNB and a plurality of remote antenna arrays distributed spatially over a geographical area. The management server causes each remote antenna array of the plurality of remote antenna arrays to obtain one or more signal synchronization block (SSB) signals in a mmWave frequency band from the gNB via a dedicated communication medium. Each remote antenna array of the plurality of remote antenna arrays obtains different SSB signals via the dedicated communication medium. The management server further causes each remote antenna array of the plurality of remote antenna arrays to execute beamforming to direct one or more beams of RF signals corresponding to the obtained one or more SSB signals to serve its corresponding UEs.

  • Patent number: 9059782
    Abstract: Certain embodiments of the invention may be found in a method and system for antenna and radio front-end topologies for a system-on-a-chip (SOC) device that combines Bluetooth and IEEE 802.11 b/g WLAN technologies. A single chip radio device that supports WLAN and Bluetooth technologies receives a WLAN signal in a WLAN processing circuitry of the radio front-end and in a Bluetooth processing circuitry of the radio front-end. Signals generated by the WLAN processing circuitry and the Bluetooth processing circuitry from the received WLAN signal may be combined in a diversity combiner that utilizes selection diversity gain combining or maximal ratio combining (MRC). When a generated signal is below a threshold value, the signal may be dropped from the combining operation. A single antenna usage model may be utilized with the single chip radio device front-end topology to support WLAN and Bluetooth communications.

  • Patent number: 9026048
    Abstract: A near field communications (NFC) device is disclosed that detects a presence of another NFC capable device within its magnetic field. The NFC device observes signal metrics of an observed detection signal at various intervals. The NFC device determines a statistical relationship based upon at least two first signal metrics from among the signal metrics to determine an estimate of at least one second signal metric from among the signal metrics. The NFC device compares a difference between the estimate of the signal metric of the at least one second signal metric and the at least one second signal metric. The NFC capable device makes a first determination that another NFC device is present within its magnetic field when the difference indicates that the at least one second signal metric is non-linearly related to the at least two first signal metrics.
