摘要： Techniques for using at least one of omni-directional and directional antennas for communication are described. A station may be equipped antenna elements selectable for use as an omni-directional antenna or one or more directional antennas. The station may select the omni-directional antenna or a directional antenna for use for communication based on various factors such as, e.g., whether the location or direction of a target station for communication is known, whether control frames or data frames are being exchanged, etc.

摘要： Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.

摘要： An apparatus includes a processing system configured to establish a link with any one of a plurality of access points in a mesh network, each of the access points providing the apparatus with a different data path through the mesh network. The processing system is further configured to compute a metric for each of the data paths and select one of the access points to establish the link with based on the metrics. In a centralized mesh network, an apparatus includes a processing system configured to compute, for each of the access points, a metric for each of a plurality of data paths supportable by that access point, and establish interconnections between the access points based on the metrics.

摘要： Traffic streams through mesh points in a mesh network are managed. Data arriving at the mesh point are aggregated in packet queues. The packet queues segregate arriving data by the data's Quality of Service (QoS) requirement. An appropriate communication channel is selected. The communication channel is accessed through a contention access schema. An M-Request-To-Send (MRTS) message is sent to potential receiving mesh points with receiving mesh points responding with an M-Clear-to-Send (MCTS) message. Data from the packet queues is transmitted to the next mesh point. A mesh point power save mode allows battery operated mesh points to sleep preserving power.
摘要翻译：通过网状网络中的网点进行流量管理。到达网格点的数据被聚合在数据包队列中。数据包队列根据数据的服务质量（QoS）要求隔离到达的数据。选择适当的通信通道。通信通道是通过争用访问模式访问的。将M-Request-To-Send（MRTS）消息发送到具有以M-Clear-to-Send（MCTS）消息响应的接收网点的潜在接收网点。来自分组队列的数据被发送到下一个网格点。网点省电模式允许电池操作的网点保持功率睡眠。
