摘要： Implementation of opportunistic use of stations in a wireless network as repeaters is described. In one implementation, a station detects the existence of rate anomaly in a wireless network. In response to the rate anomaly, the station may transform into a software repeater for certain other neighboring stations. The repeater function allows for the relaying of packets sent by these neighboring stations to the access point and vice versa. The other neighboring stations, owing to their relative proximity to the repeater station, transmit data at a higher rate to the repeater station. Thus, the removal of the slower stations reduces clogging of the access point and increases the overall data rate within the wireless network. Further, a zero-overhead network coding protocol may be implemented in conjunction with the repeater function to increase capacity of the wireless network.

摘要： The subject disclosure is directed towards configuring and controlling wireless flyways (e.g., communication links between server racks provisioned on demand in a data center) to operate efficiently and without interfering with one another. Control and flyway selection may be based upon steered antenna directionality, channel, location in the data center, transmit power, and measured and/or predicted (estimated) network traffic. Flyways also may be used to route indirect traffic to reduce traffic on a bottleneck (e.g., wired) link. A payload may be sent over a over a wireless flyway with acknowledgment via a wired backchannel so that wireless communication is in one direction. The lack of interference and communication in one direction facilitates flyway operation without a backoff function and/or without clear channel assessment.
摘要翻译：主题公开涉及配置和控制无线飞行路线（例如，在数据中心中按需提供的服务器机架之间的通信链路），以有效地操作并且彼此不干扰。控制和飞行选择可以基于导向天线方向性，信道，数据中心中的位置，发射功率以及测量和/或预测（估计的）网络业务。飞行路线还可用于路由间接流量以减少瓶颈（例如，有线）链路上的流量。有效载荷可以通过无线飞行通过经由有线后向信道的确认发送，使得无线通信在一个方向上。在一个方向上缺乏干扰和通信便于没有退避功能的飞行操作和/或没有明确的信道评估。

摘要： A method and system for optimizing channel access scheduling for multiple wireless computing devices over a wireless network improves channel access efficiency with respect to a primary channel. An access point, or host computer, includes a host transceiver for receiving control information from the wireless computing devices over a low power channel. Upon receiving the control information, the access point applies a scheduling algorithm to schedule channel access for the wireless computing devices to transmit data over the primary communication channel. The wireless computing devices include a low power radio for receiving scheduling information via the low power channel during idle periods. When the scheduling information is received, the wireless computing device activates its primary channel network interface components to communicate data through the primary channel. When the computing device is idle, the device is configured to power down all of its components with the exception of the circuitry required to power the low power channel. As such, the low power channel is maintained in an active state for receiving scheduling information, such as an access schedule, during both idle and non-idle periods.

摘要： An invention is disclosed whereby a wireless network node, equipped with two or more radio transceivers statically tuned to non-interfering frequency channels, can make decisions regarding which channel to use when communicating with a neighboring wireless node. A multi-radio unification protocol implemented in a wireless node coordinates the use of multiple wireless network interface cards and provides a virtual layer that hides the multiple physical network interfaces from higher layers of a node's network protocol stack. The invention is applicable to wireless networks generally, including those in which some nodes do not have multiple radios or do not recognize the multi-radio unification protocol. The invention makes possible simultaneous transmissions using available channels, thereby reducing interference and delay while increasing the overall capacity of the network.

摘要： Described herein is an implementation that reduces the battery consumption of an energy-constrained computing device that is capable of communicating over a wireless network. As conditions and circumstances warrant, the implementation selects one of multiple radios (e.g., two)—with each having a unique combination of characteristics (in terms of power-consumption, data-rate, range and/or frequency band of operation) for wireless communications to and from a wireless device. The implementation selects one radio to minimize power-consumption while maintaining effective wireless data communication. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
