  • Patent number: 9479935
    Abstract: A collocated device functioning as a configurator can use short and long button activations to enter a configuration state, open a timing window, and force client devices currently joined to a network to rejoin the network. If the collocated device functioning as a configurator is unconfigured, a short (or long) button activation can initiate a configuration sequence. A short button activation on that same collocated device, once configured, can cause the device to open a configurator timing window, during which one or more devices can be provided the information necessary to securely communicate on a network. A long (or short) button activation can be used to force all currently connected client devices, or rejoin the network using a new Service Set Identifier (SSID) or passphrase.

  • Publication number: 20160302057
    Abstract: Subsequent association identifier (AID) update within single user, multiple user, multiple access, and/or MIMO wireless communications. Even while a given communication device maintains continuous association within a given communication system, a unique identifier associated with that particular communication device may be updated. For example, considering and implementation including an access point (AP) and a number of wireless stations (STAs), even while at least some of the STAs remain in association with the AP, the respective unique identifiers associated with one or more of those STAs may be updated (e.g., the respective AID values associated with one or more of those STAs may be updated). For example, after an initial assignment of unique identifiers associated with a group of respective communication devices within the communication network, the unique identifier associated with one or more of those respective communication devices may be updated or changed after the initial assignment.
