The techniques described simplify the process of associating wireless devices with wireless networks. Wireless devices can associate with a wireless access point without knowing details of the wireless access point, such as a service set identifier (SSID). Upon associating with a wireless access point, client devices cease transmission of or reduce a transmission rate of wireless probe requests, resulting in more efficient wireless radio frequency use and reduced possibility of interference due to wireless probe request transmissions.

Abstract: The present disclosure discloses a system and method for. classifying Wi-Fi signals from Fourier transform samples. Generally, classifying Wi-Fi signals from Fourier transform samples includes: collecting and dividing Fourier transform samples into frequency blocks; determining the bandwidth for the Fourier transform sample; and determining whether the Fourier transform sample corresponds to a narrowband signal. Further, if a determination is made that the Fourier transform sample does not correspond to a narrowband signal, channel utilization is calculated based on a determination that the FFT sample corresponds to a Wi-Fi signal. If it is determined that the Fourier transform sample corresponds to a narrowband signal, then a determination is made that the FFT sample corresponds to a Wi-Fi signal based on certain criteria. The certain criteria may include one or more of a slope value, a number of sub-peak bins, an analysis of adjacent channels, characteristic matching, or other criteria.

Abstract: System and methods are provided for dynamically setting a threshold signal-to-noise ratio for probe requests for one or more access points in a wireless network based on several factors, including density/distance between access points and/or current and expected load on access points.

In particular, an access point may ignore client device probe requests when another access point may be better positioned to handle such a request and/or when the access point would be unable to meet expected load requirements if such an associate were made.

Abstract: Disclosed herein, one embodiment of the disclosure is directed to a system, apparatus, and method for location estimation in the presence of multipath/non-line-of-sight (NLOS) conditions. Various methods have been contemplated to detect the level of multipath/NLOS propagation between two devices. A SNR variation method determines how the SNR of each chain/stream is varying over a time window in order to detect the chain/stream with least local scattering or multipath. A measure of coherence SNR is defined to measure the level of multipath/NLOS per-chain/stream. Moreover, since per-subcarrier SNR information is available at the one or both nodes, the coherence methods can be used on a per-subcarrier basis to detect multipath/NLOS for the entire channel, for the specific spatial stream or for the specific frequencies occupied by the subcarriers. Furthermore, a coherence bandwidth estimation method uses the SNR variation over subcarriers to detect the coherence bandwidth of the spatial stream.

Abstract: The present disclosure discloses a method and network device for efficient frame aggregation. Specifically, a network device queues a first set of packets until one of the first set of aggregation limits is detected. The network device then transmits the first set of packets, and receives feedback information. Then, the network device modifies the first set of aggregation limits to obtain a second set of aggregation limits based on the feedback information. The network device queues a second set of packets until one of the second set of aggregation limits is detected, and then transmits the second set of packets. Also, the network device determines whether a received packet has a particular characteristic. If so, the network device transmits the first set of packets before at least one of the first set of aggregation limits is detected.

Abstract: A network device includes a communication interface and a processor. The communication interface may receive a multicast stream that includes a frame. The processor is coupled to the communication interface and may determine whether to send the frame unicast or multicast. The communication interface transmits the frame unicast or multicast based on the determination by the processor. The determination by the processor may be based on characteristics of the frame. If the characteristics of the frame include characteristics of a key frame such as an I-frame, the processor may determine to transmit the frame unicast. The determination may also be based on a predetermined state of client devices that are to receive the frame. If a client device is in a predetermined state such as a power save state, the processor may determine to transmit the frame unicast to that client device. Other embodiments are also described.

Abstract: Methods and systems are described for filtering out signal strength data associated with access points and a client device using heuristic and intra-access point analysis. The filtered data may be used to approximate the location of the client device. By filtering signal strength values through a heuristic and intra-access point analysis; the systems and methods described eliminate inaccurate or anomalistic values, which may negatively alter the estimated location of the client device. Accordingly, the systems and methods may produce more accurate client device location estimates by intelligently examining detected signal strength values.

Abstract: When an access point (AP) is first powered up, it lacks provisioning information such as channel numbers, power levels, SSIDS, security settings, and so on. The process of supplying this information required to get the AP operating as part of a network is called provisioning. An unprovisioned AP in a swarm first attempts to obtain a DHCP address. Once it gets a DHCP address or selects an address such as from the link-address (169.254.xx.xx) group, it advertises a predetermined wireless SSID.

Thereafter, transmission of the alert message is suppressed in response to verifying that the intrusion event has been erroneously determined.
