20130303232 | METHODS AND APPARATUS FOR LOCATION-BASED PARAMETRIC CONTROL - Methods and apparatus for location-based control of parameters such as radio frequency (RF) transmission characteristics of a wireless device. In one embodiment, a determination of a maximum allowable level for a given characteristic associated with the location of the wireless device is made, and the transmission characteristic of the wireless device is adjusted based at least in part on this maximum allowable level. The location may correspond to a regulatory domain with specific requirements for wireless transmitters. A database is referenced to retrieve these requirements. The maximum allowable levels are derived from the requirements. Thus, exemplary wireless devices are capable of universal regulatory compliance. | 11-14-2013 |

20140365669 | Device and Method for Associating with WiFi Networks - A method automatically connects a device to a WiFi network. The method includes determining WiFi networks that are available for a connection thereto. The method includes categorizing each of the WiFi networks as a private WiFi network or a public WiFi network in which the private WiFi network utilizes a first association process while the public WiFi network utilizes a second association process. The method includes executing a first automatic connection process using the first association process until a successful connection is established to one of the private WiFi networks based upon a first prioritized list. The method includes executing a second automatic connection process until a successful connection is established to one of the public WiFi networks based upon a second prioritized list when the first automatic connection process to the private wireless networks is unsuccessful. | 12-11-2014 |
20150092652 | Wireless Multicast Communication - This document describes multicast communication between wireless devices. A scheduling frame may be wirelessly transmitted by a wireless device. The scheduling frame may include a multicast address indicating a group of intended receiving devices for a payload frame. The scheduling frame may further include scheduling information indicating an order for the group of intended receiving devices to transmit acknowledgement information for the payload frame. A payload frame may also be wirelessly transmitted by the wireless device. The payload frame may include payload information intended for the group of intended receiving devices. Additionally, acknowledgement frames may be wirelessly received by the wireless device from at least a subset of the group of intended receiving devices. The acknowledgement frames may be received according to the order indicated in the scheduling information. | 04-02-2015 |
20150350875 | Device and Method for Basic Service Set Transition Management - A method, station and computer readable storage medium used to perform a roaming procedure. The method performed by the station including determining whether a roam is to be performed, the station being associated with a first access point (AP), receiving network related information for at least one second AP, determining a score value for each of the at least one second AP based upon the network related information, the score value being either a quantitative score calculated as a function of a respective received signal strength indicator (RSSI) value and a respective load value or a qualitative score calculated as a function of a preference value and the RSSI value, selecting one of the at least one second AP based upon the score values and roaming from the first AP to the selected one of the at least one second AP. | 12-03-2015 |
20150350911 | System and Method for Temporarily Joining a WiFi Network - A system, method and station used to establish a guest connection to a WiFi network. A first station establishes a first connection to a second station using a first communication mechanism, receives a data block from the second station, the data block including network information based upon a Basic Service Set (BSS) identification (BSSID) corresponding to a access point of a WiFi network to which the second station has connected, authentication information for connecting to the WiFi network and a time field indicating an amount of time the first station is allowed to access the WiFi network using the data block, establishes a second connection to the WiFi network using a second communication mechanism based upon the network information and authentication information of the data block and disconnects the second connection when the amount of time expires. | 12-03-2015 |
20150350933 | Wireless Link Quality Monitoring - Wi-Fi link health monitoring by a wireless device. Signal strength (e.g., RSSI) of a Wi-Fi link may be monitored. If the signal strength is low, further link quality metrics may be monitored. If it is determined that health of the Wi-Fi link is poor based on monitoring signal strength and other link quality metrics, roaming to a different Wi-Fi network may be performed, the Wi-Fi link may be disconnected, and/or an application processor of the wireless device may be woken. | 12-03-2015 |
20150350957 | Device and Method for Reliable WiFi Data Connectivity - A station and non-transitory computer readable storage medium for determining a first physical layer rate to perform data transmissions between the station and an access point of a WiFi network, the first physical layer rate being based on a primary rate and a plurality of fallback rates associated with the access point, the primary rate having a higher transmission speed than the plurality of fallback rates, determining a trigger based upon at least one current condition of the station and at least one corresponding prior condition existing at a time when the first physical layer rate is determined, selecting one of the plurality of fallback rates when the trigger is determined, performing data transmissions between the station and the access point using the one of the plurality of fallback rates and determining a second physical layer rate based on the one of the plurality of fallback rates. | 12-03-2015 |
