Abstract: A method and system for improving spatial reuse in a wireless local area network (WLAN) by per-client dynamic power management. Each access point of the WLAN associates each of its clients with a minimum power level. A central controller of the WLAN generates a schedule for transmission at different power levels, and each access point varies its transmission power level based on the schedule. An access point transmits data packets, at the scheduled transmission power level, to clients associated with a minimum power level that is less than the scheduled power level.

Abstract: Described herein are various technologies pertaining to scheduling data transfer between a mobile computing device and a base station in a cellular network. A signal quality value for a signal over which data is to be transferred is computed, and transfer of data is scheduled based upon the signal quality value. If the signal quality value is above a threshold, a wireless radio of the mobile computing device is caused to commence data transfer or continue data transfer. If the signal quality value is below the threshold, and the data need not be immediately transferred, then the wireless radio is caused to transition to an idle state or remain in an idle state.

Abstract: A multiple independent narrow-channel wireless network and method for transmitting and received data over a wireless network using a fragmented frequency spectrum. The system and method uses a plurality of narrow wireless channels obtained from splitting a wide wireless channel. Each narrow channel performs sending, receiving, and carrier sensing. Moreover, each narrow channel is independent such that data can be sent or received without any interference from other narrow channels and without synchronization. Embodiments of the system and method include a compound radio having a compound receiver and a compound transmitter. The compound transmitter includes an inter-radiolet symbol synchronization module, to permit use of a single inverse fast Fourier transform block, and a dynamically configurable filter array, to mitigate leakage between channels. The compound receiver uses fraction data rate processing to optimize efficiency. A throughput maximal metric technique is used to determine its frequency of operation in white spaces.

Abstract: One or more mobile devices and a cloud server computing device are utilized to provide Internet access to one or more client computing devices. One of the clients is designated as a Wi-Fi access point. The Wi-Fi access point implements a reverse-infrastructure Wi-Fi mode which tethers available mobile devices and other clients to the access point. The cloud server periodically computes an optimal number of the mobile devices to be used for data striping, and transmits a webpage to a requesting client by striping data associated with the webpage across the optimal number of the mobile devices.

Abstract: A “Wi-Fi Multicaster” provides a practical and efficient Wi-Fi multicast system for environments having potentially large numbers of Wi-Fi clients. Significantly, the Wi-Fi Multicaster does not require any changes to the 802.11 protocol, or to the underlying Wi-Fi infrastructure. In various embodiments, the Wi-Fi Multicaster uses pseudo-broadcast, and augments it with destination control, association control and optional proactive FEC (forward error correction) to improve multicast performance. More specifically, the Wi-Fi Multicaster system converts multicast packets to targeted unicast transmissions. To minimize the amount of airtime consumed, the Wi-Fi Multicaster uses destination control in combination with various algorithms for association control. Further, in various embodiments, the Wi-Fi Multicaster includes an adaptive, proactive FEC scheme to reduce overall packet losses. Finally, to overcome the challenges posed by encryption protocols such as 802.1x, the Wi-Fi Multicaster uses a “virtual multicast interface” that allows clients to “share” a common key for each multicast.
Abstract translation: Wi-Fi Multicaster为具有潜在大量Wi-Fi客户端的环境提供了实用且高效的Wi-Fi组播系统。 重要的是，Wi-Fi Multicaster不需要对802.11协议或底层Wi-Fi基础设施进行任何更改。 在各种实施例中，Wi-Fi Multicaster使用伪广播，并且将其与目的地控制，关联控制和可选的主动FEC（前向纠错）相加以提高多播性能。 更具体地说，Wi-Fi Multicaster系统将多播分组转换为目标单播传输。 为了最大限度地减少消耗的通话时间，Wi-Fi Multicaster将目的地控制与各种算法结合使用，进行关联控制。 此外，在各种实施例中，Wi-Fi多播卡器包括自适应主动FEC方案以减少总体分组丢失。 最后，为了克服802.1x等加密协议带来的挑战，Wi-Fi Multicaster使用虚拟组播接口，允许客户端共享每个组播的公共密钥。
