  • Publication number: 20240098492
    Abstract: During operation, an access point may provide a first WLAN and a second WLAN, where the first WLAN uses a WPA2-compatible authentication protocol and the second WLAN uses a WPA3-compatible authentication protocol. In response to an association request or a probe request associated with (or from) an electronic device, the access point may establish a connection with the electronic device using the first WLAN. Then, the access point may confirm, with a computer system, that a binding between a passphrase associated with the electronic device and the second WLAN exists. Alternatively, when the binding does not exist, the access point may establish the binding in the computer system. Next, the access point may perform a BSS transition of the electronic device from the first WLAN to the second WLAN.

  • Patent number: 8437361
    Abstract: Techniques are provided herein to adaptively and independently disable use of subchannels in transmission sent from a first wireless communication device to a second wireless communication device. The first wireless communication device receives transmission sent to it by the second wireless communication device. The transmissions occupy some or all of a plurality of subchannels within a frequency band that are available for use in the transmission. The transmissions received at the first wireless communication device are evaluated in each subchannel for an over-the-air wireless link between the first wireless communication device and the second wireless communication device. Based on the evaluation, zero or more of the plurality of subchannels are independently disabled in transmissions that are sent by the first wireless communication device to the second wireless communication device.

  • Patent number: 7706812
    Abstract: A system and method are provided for detecting locations of a customer premises equipment in a wireless communication system with one or more base transceiver stations and one is efficient. A plurality of antennas in a base transceiver station (BTS) receives signals transmitted from a customer premises equipment (CPE). A timing detection module extracts the timing offset from the receiving signals and a first calculation module calculates the distance between the BTS and the CPE based on the timing offset. A signal detection module detects magnitudes and phases of the receiving signals and a second calculation module determines a dominant beam according to the antenna pattern and calculates the direction of arrival of the dominant beam. A third calculation module calculates the location of the CPE relative to the BTS based on the distance and the direction of arrival.
