    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: 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.

    摘要: Embodiments herein relate to transmitting information from wireless access points (WAP) sharing a same frequency channel that is part of an industrial, scientific and medical (ISM) radio band. During a beacon transmit period (BTP), the WAPs transmit a beacon. Then, a first WAP is to collect information from at least one of the plurality of communication devices (CD) associated with the first WAP during a control access period (CAP). Next, the first WAP transmits the collected information during an open access period (OAP).

    摘要: A wireless network device includes operating system layer buffers used by an operating system and driver layer buffers used by a wireless network interface driver in the device. Memory stores a capacity bitmap managed by the wireless network interface driver. The capacity bitmap identifies a current capacity of each of the driver layer buffers and the capacity bitmap may be provided to the operating system.

    摘要: Channel assignment for access points (APs) in a wireless network includes determining at least one of a MaxSum and a MaxMin, and determining a channel assignment for the APs based on at least one of the MaxSum and the MaxMin. The MaxSum is a maximization of a system throughput and the system throughput is a sum of throughput of nodes in the network. The MaxMin is a maximization of a minimum throughput of a set of AP-client links in the network. The AP-client link is a link between an AP and a client associated with the AP.
