    • 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.
    • 一种通信系统,其中接入点和通过接入点通信的一个或多个设备自适应地应用正交频分多址(OFDMA)。 接入点可以像传统OFDMA那样将正交子载波分配给设备,但是接入点感测对子载波的活动,并且选择没有用于分配的活动的子载波。 在替代方法中,配置用于OFDMA通信的设备可以从不支持OFDMA的设备接收信道分配。 具有OFDMA能力的设备可以仅使用所分配的信道中的子载波的一部分,其可以被传送到非OFDMA设备。 在非OFDMA设备期间,可以忽略错误检测和校正中的未使用的子载波,以避免将通信错误地分类为错误的。 关于OFDMA能力,子载波分配和正在使用的子载波的信息可以作为诸如信标和探测消息的网络控制通信中的信息元素传送。

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.
