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.

摘要： A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.
