Abstract: Techniques for proving enterprise mode security for relays are disclosed. For example, enterprise mode security based on IEEE 802.1x is provided for relays or other similar devices to extend the coverage of access point hotspots or other similar access point use cases. According to one aspect, a relay incorporates an authentication client associated with an authentication server. According to another aspect, a four address format is employed for tunneling messages via a relay between a station and an access point. According to another aspect, a cryptographic master key associated with an access point and a station is provided to a relay to enable the relay to be an authenticator for the station.

Abstract: A system and method for wireless devices to efficiently receive communications by transmitting and receiving specialized beacon messages. Particularly, a wireless device may await reception of a synchronizing beacon message from a transmitting device. A relative position identifier within the synchronizing beacon message may then allow the wireless device to anticipate future beacon message transmissions and to synchronize its reception pattern with the transmitter. In this manner the wireless device need only receive and decode beacon messages germane to its operation.

Abstract: Systems, methods, and devices provide for efficient access point discovery. One implementation generates a wireless frame to include a first indication of a service set identifier of the access point, and a second indication of a format of the first indication. The frame is then transmitted on a wireless medium. In some aspects, the first indication is a hash of a service set identifier of the access point, for example, a cyclic redundancy check (CRC) value of the service set identifier.

Abstract: Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. A method operational in a receiver device, includes monitoring one or more repurposed channels within a television broadcast frequency spectrum for data waveforms, wherein waveforms of different bandwidths coexist within the one or more repurposed channels, and at least a larger waveform has a first bandwidth larger than a channel bandwidth for each repurposed channel. The method also includes receiving a waveform over a repurposed channel from among the one or more repurposed channels, wherein the received waveform has a second bandwidth smaller than the channel bandwidth. The method further includes processing the received waveform by applying a downclocking factor to a clock of the receiver device that causes the receiver device to process the received waveform according to the second bandwidth to obtain a data payload from the received waveform.
