摘要： Various techniques and systems are provided for determining a location of a target wireless device. Specifically, various techniques and systems are provided for determining a location of a wireless device using timestamps assigned to communications transmitted between the wireless device and one or more other wireless devices on a same WiFi channel as the wireless device. Implementations describe devices, computer-program products, and methods including transmitting a first frame by a network device on a channel of a radio frequency band, assigning a first timestamp to the frame, assigning a second timestamp to a second frame, determining a time difference between the first timestamp and the second timestamp, receiving an alternative time difference corresponding to an alternative network device, and determining a location of the client device using the time difference and the alternative time difference.

摘要： The present disclosure discloses a method and system for adaptive cell size management. The system can determine a minimum SNR value and one or more current environmental factors for a particular environment. Also, the system dynamically determines a minimum signal strength value for receiving wireless signals based on the minimum SNR value and the one or more current environmental factors, and configures a network device to receive signals with the minimum signal strength value. Alternatively, the system can estimate a particular coverage area such that a first set of wireless signals transmitted by devices located within the particular coverage area reach a network device at a minimum signal strength. The system then computes a transmission power such that a second set of wireless signals transmitted by the network device at the transmission power reaches an edge of the particular coverage area at a particular signal strength value.

摘要： Embodiments of the present disclosure relate to physical layer resource utilization in wireless local area networks. In particular, the present disclosure relates to a policy-based control mechanism for wireless network physical layer resources such as transmit beamforming. Specifically, the disclosed system receives a set of network policy criteria, and information associated with each of a plurality of client devices connected to a network device. The disclosed system then selects a subset of client devices in a wireless network based on the set of network policy criteria and information associated with each of the plurality of client devices. Furthermore, the disclosed system provides the subset of client devices for using one or more of wireless network physical layer resources. Here, the wireless network physical layer resources are limited to a threshold number of client devices. Moreover, the number of client devices in the subset does not exceed the threshold number.
