Abstract: A wireless device implements power saving logic for two or more wireless clients that concurrently communicate on a shared wireless channel (single channel concurrency). When one of the wireless clients transitions from power save mode to active mode (e.g., in response to a beacon signal), the power saving logic causes the other wireless client(s) to transition to active mode as well. Each wireless client ‘awakened’ in this manner transmits a NULL frame having a power management bit set to a logic ‘0’ value to an associated access point (AP), thereby indicating its active status to the associated AP. As a result, all of the wireless clients may concurrently receive buffered data from their associated APs on the shared wireless channel. If the ‘awakened’ wireless client(s) do not need to transition to active mode in response to their next received beacons, power consumption of the wireless device is advantageously reduced.

Abstract: Embodiments relate to systems and methods for enabling stations to connect to wireless hotspots using non-Unicode service set identification information. A WiFi™ wireless router or other access point can broadcast beacon information to smart phones or other stations within wireless range of that device. In existing access point implementations, the character set in which the access point broadcasts this information, including a service set identification indicating the connection services available from the access point, are assumed to be encoded in Unicode format, specifically, UTF-8 format. While English-language options are properly displayed, character sets and/or languages which are not encoded in Unicode (UTF-8) format are translated into unintelligible characters using this approach. According to embodiments, access point hardware can be configured to broadcast the type of character set encoding in the beacon information itself, for instance, in existing SSID information elements, vendor-specific information elements, and/or other locations in the beacon data.
