    摘要： Security techniques and security mechanisms for wireless networks that transmit content such as advertisements. According to exemplary techniques, control messages comprising unrequested content (e.g., advertisement data) may be transmitted in response to a request from a client device, while in other exemplary techniques the control messages may be transmitted without any request from a client device. In some exemplary implementations, security mechanisms such as public key cryptography algorithms may be used to secure transmissions. In some of these techniques which implement public key cryptography, a user may be required to retrieve a public key from a source other than the wireless access point transmitting encrypted advertisements (e.g., a sign or terminal in a commercial entity transmitting such advertisements, or from a web service), such that the user may confirm that the encrypted content is from a source matching the retrieved public key and thus confirm the authenticity of a wireless access point.

    摘要： An advertising framework for transmitting advertisements from wireless access points to client devices that need not be connected to the wireless access point. The client device can display the advertisements on a user interface of the client device. Such advertisements may be transmitted, for example, as part of a control message transmitted by a wireless access point of a wireless network, or other message conventionally used to broadcast network characteristics necessary for a client device to establish a connection to the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including announcement transmissions such as beacons, may be used for control messages.

    摘要： A wireless access point in a wireless network that may be adapted to transmit location data indicating its location to other devices within range, including other wireless access points and client devices. In some embodiments of the invention, the location data may be embedded in a control message or announcement transmission transmitted by the wireless access point, or other message conventionally used to broadcast network characteristics necessary for a client device to establish a connection to the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions. The other wireless access points and client devices may receive the location data broadcast by the wireless access point without establishing a connection to the client device. Devices receiving the location data may use the received location data to determine their own locations, and may provide the determined locations to consumers of location data.

    摘要： A system and method for providing the ability to discover the capabilities of a user's computer to determine whether it is capable of supporting more than one wireless protocol simultaneously is provided. A computing device's capabilities (including, for example, hardware and/or software capabilities) is checked to determine if it supports at least two specific wireless protocols and checking a computing device's capabilities (including, for example, hardware and/or software capabilities) is checked to determine if it supports both wireless protocols simultaneously. The techniques for determining the computing device's compatibility may include comparing lists of protocol requirements to lists of system capabilities and/or generating test signals by the system according to the protocol.

    摘要： A communication system in which an access point and one or more devices communicating through the access point adaptively apply Orthogonal Frequency Division Multiple Access (OFDMA). The access point may assign orthogonal subcarriers to devices as in conventional OFDMA, but the access point senses activity on the subcarriers and selects subcarriers without activity for assignment. In an alternative approach, a device that is configured for OFDMA communication may receive a channel assignment from a device that does not support OFDMA. The OFDMA-capable device may use only a portion of the subcarriers in the assigned channel, which may be communicated to the non-OFDMA device. During the non-OFDMA device may then ignore unused subcarriers in error detection and correction to avoid incorrectly classifying communications as erroneous. Information about OFDMA capabilities, subcarrier assignments and subcarriers in use may be communicated as information elements in network control communications, such as beacons and probe messages.
