摘要： Techniques which prevent rogue devices from continued access to a wireless communication system. A control element directs access points as to which mobile stations to service. Each access point maintains a record of the mobile stations it is servicing. At the direction of the control element, one or more access points send ACK (acknowledgement) messages when hearing messages from a rogue device. When the rogue device sends a message, it expects an ACK message in response, but those additional ACK messages interfere with the responsive ACK message, causing the rogue device to never hear the responsive ACK message. The rogue device assumes its message was not received, so it retries sending of that message. When the rogue device retries sending of its message, the responsive ACK message is similarly interfered with, until the rogue device concludes that its connection has been lost.

摘要： An 802.11-compliant device for high throughput is disclosed. A plurality of TCP packets received in a buffer for transmission are stored. The plurality of TCP packets can be aggregated as A-MSDU sub-frames to form a A-MSDU frame in accordance with an IEEE 802.11 standard. Additionally, a plurality of A-MSDU frames can be aggregated as A-MPDU sub-frames to form a A-MPDU frame. The A-MPDU frame is compliant with a number of allowable sub-frames and a maximum size in accordance with an 802.11 standard. The A-MPDU frame is sent for transmission as an IEEE 802.11 packet.

摘要： Reliable multicast delivery in wireless communication, even when a WS doesn't know its AP, is determined at the AP without the sending device. Multicast packets are received at each AP having destinations. Without altering those packets, the AP encapsulates them in an A-MSDU packet. Each A-MSDU packet is sent individually to each destination, and might encapsulate more than one multicast packet. Destinations might receive two streaming messages faster than if sent separately. AP's might choose a 1st multiple of multicast packets from a 1st source, a 2nd, different, multiple of multicast packets from a 2nd source, and a single multicast packet from a 3rd source. Individualized optimization of transmission parameters for each A-MSDU packet and each multicast packet therein. Individualized optimization of transmission parameters for the A-MSDU packet for each destination. The AP collectively optimizes delivery of distinct multicast packets to different destinations.

摘要： ACK messages by access points are suppressed when those access points receive messages from wireless stations for which those access points should not respond. This might occur in wireless communication systems based upon 802.11 protocols in which seamless mobility is desired, with a system controller that assigns wireless stations to specific access points. The access point examines an incoming message from a wireless device to decide whether or not to suppress a responsive ACK message to that wireless device. An access point may suppress an ACK message by suppressing the generation of the ACK, or by suppressing the transmission of a generated ACK. Mechanisms for suppressing an ACK message include setting the ACK transmission to a relatively unpowered transmitting antenna; interrupting a PHY-layer element during receipt of an incoming frame; and limiting entries in a key cache table to suppress ACK messages in response to encrypted incoming frames.
摘要翻译：当这些接入点接收来自这些接入点不应响应的无线站的消息时，接入点的ACK消息被抑制。这可能发生在基于802.11协议的无线通信系统中，其中无线移动性是期望的，系统控制器将无线站分配给特定的接入点。接入点检查来自无线设备的进入消息以决定是否抑制对该无线设备的响应ACK消息。接入点可以通过抑制ACK的生成或通过抑制所生成的ACK的发送来抑制ACK消息。用于抑制ACK消息的机制包括将ACK传输设置为相对无动力的发射天线; 在接收到帧期间中断PHY层元素; 并且限制密钥高速缓存表中的条目以响应于加密的传入帧来抑制ACK消息。

摘要： A system and method for optimizing voice communications in a wireless network including an AP having a message waiting time that provides proper QoS while losing minimal communication bandwidth. The QoS may be responsive to the amount of user traffic in both the AP and neighboring APs. The method may include setting parameters for each level of QoS in response to a measure of the degree of contention for that level of QoS, and in response to a measure of the degree of contention for those levels of QoS with higher priority, and setting waiting time parameters in response to a stochastic model of contention at each level of QoS. Operational parameters might include contention window time, AIFS time, and back-off value(s), and might be modified in response to message QoS.

摘要： A system and method enable the transmission of messages between a source device and a wireless station. A first message is received at an access point from the source device. The access point transmits the first message to the wireless station and stores a copy of the first message in a memory. The access point receives an acknowledgement message from the wireless station and transmits a proxy acknowledgement message to the source device. The access point transmits a control message to the source device to limit the number or size of additional messages sent from the source device based on a number or size of messages currently stored in the memory and a maximum number or size of messages that can be stored in the memory.

摘要： A method wherein a message packet is received at a node in a 1st wireless communication system, wherein said 1st wireless communication system determines whether it is experiencing interference with a 2nd wireless communication system, and wherein said 1st wireless communication system takes action to reduce said interference. Reducing said interference might include reduction in signal strength, change in message coding, and other actions, in response to a set of selected interference thresholds. Different protocol effects might be changed in response to one or more said thresholds, with the effect that distinct wireless communication systems may operate in relatively close proximity with a minimum of interference.
