  • Publication number: 20200229086
    Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

  • Patent number: 10716075
    Abstract: The present disclosure is directed to the use of active feedback from client devices to limit/regulate transmission power control of access points from the perspective of the client device. The instant transmission power control beneficially ensures that clients located at a cell edge still receive sufficient coverage from access points and have sufficient overlap with adjacent cells for seamless roaming for the wireless stations while minimizing co-channel interference. In some embodiments, the present disclosure beneficially leverages 802.11h TPC Constraint to dynamically report client's view of the RF environment and cell size estimation.

  • Patent number: 10635421
    Abstract: The present invention relates to an electronic device, a compiling method, and a computer-readable recording medium. An electronic device according to an embodiment of the present invention compiles a source code of a dynamic programming language compiled during execution of a program to the level of a static programming language compiled before execution, and may comprise a processor which determines whether the source code of the dynamic programming language generated when a command for operating the program is received can be processed by the first compiler in the same manner as the source code of the static programming language processing, and converts the source code of the dynamic programming language by the first compiler if the code can be processed as a result of the determination.

  • Patent number: 10609571
    Abstract: An algorithm for determining redundant radios in APs is disclosed. The algorithm first performs a coverage peak flattening algorithm to predict an impact to the total coverage area if a radio in a selected AP does not transmit signals in a frequency band. If the impact to the total coverage area is acceptable, the algorithm then performs a multi-point check algorithm to determine whether the radio in the selected AP is redundant in the frequency band. After determining that the radio in the selected AP is redundant in the frequency band, the algorithm transforms the redundant radio into various services based on the network deployment and user preference.

  • Patent number: 10433189
    Abstract: A flexible radio assignment algorithm that reduces co-channel interference in Wi-Fi networks is disclosed. The flexible radio assignment algorithm calculates a density value for each of the APs controlled by a network controller. The flexible radio assignment algorithm selects an AP with the highest density value and determines that a radio in the selected AP is redundant. The flexible radio assignment algorithm manages the redundant radio in the selected AP to mitigate co-channel interference in a frequency band.

  • Publication number: 20190246324
    Abstract: In one embodiment, a service receives radar data regarding usage of one or more wireless channels by a radar. The service populates a database of radar features with the received radar data. The service trains, using the database of radar features, a machine learning-based model to predict channel usages by the radar. The service causes a wireless access point to change to a different wireless channel, based on the predicted channel usages by the radar.

  • Patent number: 10257742
    Abstract: Embodiments herein describe control logic for seamlessly switching client devices between radios co-located on the same network device or between radios located on different network devices that have overlapping coverage areas. In one embodiment, the radios are assigned different channels in the same frequency band. To move the client devices between the radios, one of the radios transmits a Channel Switch Announcement (CSA) which instructs the client devices serviced by a first radio to switch to a channel assigned to a second, different radio. For example, the CSA may be used when the first radio fails, is upgraded, performs a Channel Availability Check (CAC), is overloaded, and the like. After the CSA is transmitted, the second radio spoofs the service identifier of the first radio so to the perspective of the client devices, they are still communicating with the first radio.
