摘要： Example implementations relate to access point group transmissions. For example, an access point can include instructions to determine a first mesh point to be a first hop for a first data packet and determine a second mesh point to be a second hop for a second data packet. In some examples, the access point can include instructions to group the first mesh point and the second mesh point, and utilize the group to simultaneously transmit the first data packet to the first mesh point and the second data packet to the second mesh point.

摘要： In some examples, a method can include transmitting, with an Access Point (AP), Request to Send (RTS) frames to a wireless client over a wireless medium; determining, with the AP, whether the medium is reserved by failed RTS frames for the client; and transmitting, with the AP, a frame to clear the medium when it is determined that the medium is reserved by failed RTS frames for the client.

摘要： MU-MIMO provides a mechanism for a wireless network device to transmit to multiple client devices at the same time. When employing MU-MIMO, a network device may group two or more associated client devices, and transmit beamformed signals to each group. In some implementations, a network device may initiate channel sounding. Channel sounding may include transmitting sounding frames to client devices associated with two or more basic service sets. Channel sounding may facilitate beamforming transmissions to client devices associated with the two or more basic service sets. The network device may receive feedback frames from client devices associated with the two or more basic service sets. A feedback frame may indicate how a sounding frame was received. In some implementations, the network device may further construct a feedback table from the feedback frames. The feedback table may facilitate grouping of the client devices for beamforming transmissions.

摘要： According to one embodiment of the invention, a network device comprises a plurality of antenna elements, one or more hardware processors, and a memory communicatively coupled to the one or more hardware processors. The memory comprises selective beamforming grouping logic that, upon execution by the one or more processors, aggregates a plurality of beamforming-enabled client devices within a coverage area of the network device. Furthermore, the selective beamforming grouping logic further categorizes the plurality of beamforming-enabled client devices into a plurality of groups based on a data transfer rate level supported by each of the plurality of beamforming-enabled client devices, determines a subset of client devices within a first group of the plurality of groups associated with a lowest data transfer rate level, and applies transmit beamforming simultaneously or at least concurrently for each client device of the subset of client devices.

摘要： Example methods and apparatus to generate recommendation(s) for access point association by a client device are disclosed. An example method includes calculating an effective uplink data rate for the client with respect to a first access point based on a) an uplink data rate and b) a percentage of uplink airtime available to the client. The example method includes calculating a first effective downlink data rate with respect to the first access point based on a) a downlink data rate for and b) a percentage of downlink airtime available to the client. The example method includes computing a first metric for the first access point based on the first effective uplink data rate, the first effective downlink data rate, and a noise floor scaling factor. The example method includes generating an access point recommendation by comparing the first metric and a second metric for a second access point.
