摘要： A process for secure, safe, and easy provisioning of a wireless device with credentials to connect to a wireless network. A connecting wireless device and an established wireless device both utilize low power transmission at close proximity to exchange wireless connection setting information and/or a password. The connecting wireless device is moved into proximity with the established wireless device and a low power setting is discovered at which the wireless devices may communicate with a sufficiently low error rate. The connecting wireless device is then passed the secret information by the established network device.

摘要： A wireless device that desires to be connected to a wireless network broadcasts itself and its capabilities to a network using an information element. The information element is provided with frames, such as management frames, in a channel that is not protected or encrypted. The information element is forwarded to one or more potential registrar devices. One of the registrar devices then provides configuration information to the enrollee, for example as a registrar information element. The configuration information may be passed out of band or in band, and may be passed using cryptography, which may involve public key cryptography, encryption with a PIN, or some other type of secure exchange.

摘要： A wireless station is connected to a wireless network through an access point and can establish a direct client-to-client connection to a second wireless station. The wireless station can communicate directly with the second wireless station without involving the access point. The wireless station communicates with the wired network and with other wireless stations through the access point. The second wireless station may have an infrastructure connection to the access point or may be independent.

摘要： A mechanism is provided to extend the range of wireless devices beyond the range limit that results from timing restrictions imposed by the IEEE 802.11 standard. The mechanism, which operates at the upper level of the 802.11 MAC, determines whether the wireless devices are far apart or not far apart. When the wireless devices are determined to be far apart, the standard retransmission protocol at the lower level of the 802.11 MAC is disabled and a custom ACK packet is utilized. Delivery of a transmitted packet is confirmed if the custom ACK packet is received within a maximum delay period that takes into account the longer propagation delay between wireless devices that are far apart.
摘要翻译： 提供了一种机制来扩展无线设备的范围超出由IEEE 802.11标准施加的定时限制所产生的范围限制。 在802.11 MAC的较高级别运行的机制确定无线设备是否相距甚远。 当确定无线设备相距较远时，802.11 MAC的较低级别的标准重传协议被禁用，并且使用自定义ACK分组。 如果在最大延迟周期内接收到自定义ACK分组，则考虑到远距离的无线设备之间的较长传播延迟，确认发送的分组的传送。

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.
