摘要： Methods, devices, and machine readable media are provided for transmission in a network with active and sleeping clients. Some examples can include transmitting a first multicast stream of data in response to an active wireless client being associated with the wireless network device at a particular time. The method can include transmitting a second multicast stream of the data after the first multicast stream in response to a sleeping wireless client being associated with the wireless network device at the particular time and in response to a delivery traffic indication message count expiring. The first and/or second multicast streams of the data can be retransmitted a number of times (e.g., at different data rates). An active/sleep status can be maintained for the wireless clients. A unicast stream can be transmitted when the number of clients does not exceed a threshold.

A wireless network device for an adaptive wireless network can include an application specific integrated circuit (ASIC) including logic and memory resources coupled to the ASIC. The logic can store information received from a number of clients associated with the wireless network device regarding capabilities of the number of clients in the memory resources. The logic can adapt a guard interval and/or a channel width for transmission of a data stream according to capabilities of a number of clients associated with the wireless network device.

摘要： A wireless node receives a beacon from a wireless access point. The beacon includes a wireless protocol time synchronization function (TSF) timestamp generated with reference to a global clock for a network. The wireless node synchronizes a counter according to the TSF timestamp. The wireless node receives a global timing offset (GTO) packet from the wireless access point and combines the GTO packet with a counter value to generate a global timestamp.

摘要： Methods, devices, and machine readable media are provided for wireless client authentication and assignment. Some examples can include a network device with a processing resource and a memory resource storing instructions executable by the processing resource to act as a default gateway and present a web portal for logon in response to a request from a wireless client prior to authentication of the wireless client, to send a dissociation command for the wireless client in response to an initial authentication of the wireless client, and to assign traffic to a local virtual local area network (VLAN) defined on an access point (AP) associated with the wireless client in response to a subsequent authentication of the wireless client. Some examples can include assigning the wireless client to an isolation VLAN that is tunneled via the network device prior to dissociation, where the local VLAN is not tunneled via the network device.

摘要： In an example, packets transmitted over a communication channel from a transmitter are received. Channel state information (CSI) from the received packets are obtained and signal-to-noise (SNR) values of the communication channel are computed based on the obtained CSI. In addition, effective bit error rate (BER) values are determined based on the SNR values, a coherence time period within which the effective BER values of the communication channel remain within a predetermined range is determined, a modulation and coding scheme (MCS) to be implemented by the transmitter is determined based on the effective BER values within the coherence time period, and the determined MCS is transmitted to the transmitter.
