摘要： An occupant detection system for an interior cabin area of a vehicle includes one or more signal conversion devices including conversion circuitry and a wireless control module including a multi-band transceiver having two or more transceivers. The wireless control module executes instructions to continuously send, by a first transceiver, signals on a first frequency band. The wireless control module executes instructions to receive, by a second transceiver, signals on a second frequency band from a signal conversion device. The wireless control module compares original training symbols from the signals on the first frequency band with training symbols from the signals on the second frequency band to determine a change in value of in one or more channel state information (CSI) parameters, and determines one or more occupants are present within the interior cabin area of the vehicle based on the change in one or more CSI parameters.

摘要： Methods, systems and vehicles are provided for controlling a wireless application provided to a wireless device over a wireless network. One or more radio frequency (RF) parameters of the wireless device in the wireless network are triggered by the wireless application. One or more sensors generate sensor data of the wireless device in the wireless network. A processor at least facilitates determining whether an adjustment is appropriate for the wireless device in the wireless device to mitigate interference from wireless signals outside the wireless network, based on the sensor data, wherein the determination as to whether an adjustment is appropriate is based at least on part on whether the wireless application is being utilized for the wireless device in the wireless network; and adjusting, via instructions provided by the processor, a sensitivity of a receiver of the wireless device, based on the determination that the adjustment is appropriate.

摘要： A method for use aboard a motor vehicle or other mobile system having a multi-core communication chipset includes scanning a radio frequency spectrum to identify candidate access points (APs) operating in a frequency band of the communication chipset, e.g., 2.4 GHz and 5 GHz. The method includes selecting one of the candidate APs as a first AP for connection to a primary station of the chipset. In response to a secondary station (STA-2) of the chipset being connected to an external AP on the same frequency band as the first AP, the method includes automatically disconnecting the secondary station (STA-2), then connecting the first AP to the primary station. Another candidate AP is connected to the secondary station as a second AP. The method may include simultaneously communicating with the first and second APs via the primary and secondary stations, respectively.

摘要： A system and method of facilitating wireless charging of an electric vehicle (EV) include the EV performing service discovery and negotiation via a neighborhood aware network (NaN) to determine charging compatibility of a WiFi enabled charging station or another EV with the EV. The method also includes the EV requesting a reservation from the charging station or a charge from the another EV based on determining that the EV is compatible with the charging station or the another EV by broadcasting a request message that includes a packet with the request via the NaN.

摘要： A vehicle, and methods of operating a mobile hotspot at a vehicle including a plurality of mobile hotspots, are disclosed. The method includes detecting an availability of a first one of the mobile hotspot as an access point. The method also includes delaying an availability of a second one of the mobile hotspots as an access point by a period of time after the detection of the availability of the first one of the mobile hotspots. The vehicle may include a plurality of mobile hotspots, each configured to provide wireless connectivity for one or more non-vehicle wireless devices located in the vehicle or within a proximity of the vehicle. In accordance with the method, one of the mobile hotspots may be configured to delay its availability as an access point by a period of time after an availability of at least another one of the mobile hotspots is detected.

摘要： A dynamic wireless multi-channel switch including a networking device providing access to communicate messages on at least two frequency bands. A wireless access manager module determines a utilization of each frequency band based on the communicated messages. The wireless access manager module dynamically adjusts a time slot ratio of each frequency band as a function of the utilization of the communicated messages by the networking device.
