This disclosure provides methods, devices and systems for establishing and maintaining connectivity between access points (APs) that provide multiple BSSID sets and wireless stations (STAs) that do not support enhanced multiple BSSID advertisement (EMA). In some implementations, a wireless communication device may transmit a burst of beacon frames each carrying a respective partial list of nontransmitted BSSID profiles for a multiple BSSID set. In such implementations, the bursts of beacon frames may be transmitted periodically such that the start of each burst occurs one beacon interval after the start of a prior burst. In some other implementations, a wireless communication device may broadcast multiple beacon frames each carrying a full set of nontransmitted BSSID profiles associated with a respective multiple BSSID set. In such implementations, each beacon frame may be periodically broadcast every beacon interval.

Multiple basic service set identifier (BSSID) beacon broadcast

Methods, systems, and devices are described for determining a quality estimation of a wireless network that may be used to determine whether a particular wireless network meets one or more criteria for association with a station. The quality estimation may be based on a load quality of a basic service set (BSS) of an available wireless network and/or one or more wide area network (WAN) metrics associated with the wireless network. A station may evaluate such load quality and WAN metrics prior to association, and/or after association with a wireless network.

Methods and apparatus for WiFi quality estimation based on basic service set load and wide area network metrics

Systems, methods, protocols and apparatus for information exchange and synchronization using DTMF signaling over telephone communication channels are provided. Information is packetized and converted from one format, e.g., ASCII formatted data, to another format, e.g., BCD formatted data. The information is wrapped in one or more packets by a sending apparatus, each packet including one or more headers, such as a Name and Length field that identify the information being exchanged and the amount of data included in the packet payload/value field. The data in the packets are converted from BCD to DTMF signals and are transmitted over a telephone communication line to a receiving apparatus. The receiving apparatus converts the DTMF signals back to BCD formatted data and processes the packets to obtain the information contained therein.

Systems and methods are disclosed to improve performance of a communications device receiving encrypted communications from multiple sources. The communications device is configured to increase the amount of decryption performed using a hardware-based process as compared to a software-based process by reprogramming the hardware to store a shared security key corresponding to a frame received from a source, allowing the hardware-based process to decrypt subsequent frames from that source.
