  • Patent number: 9439100
    Abstract: According to one embodiment, a network device is configured to measure a quality of service associated with a real-time streaming packet received at a first transmission rate. The network device gathers metrics to a call quality based on the quality of service, wherein the metrics are specific to a wireless call quality, and adjusts the first transmission rate to a second transmission rate based on the metrics. Herein, the second transmission rate replaces the first transmission rate to balance between a transmission delay and reliability of the real-time streaming packet.

  • Patent number: 9438557
    Abstract: The present disclosure discloses a method and network device for adaptive DHCP assignment with VLAN pool. Specifically, a network device can assign a client device to a first Virtual Local Area Network (VLAN). The network device then detects a first DHCP Discover message, transmitted by a client device, corresponding to a first VLAN. Also, the network device determines that no DHCP offer message, responsive to the first DHCP Discover message, is transmitted to the client device. Then, the network device transmits on behalf of the client device a second DHCP Discover message for the second VLAN to a DHCP server, and receives a DHCP Offer message in response to the second DHCP Discover message. The network device then assigns the client device to a second VLAN, and subsequently transmits the DHCP Offer message for the second VLAN to the client device.

  • Publication number: 20160255661
    Abstract: Described herein are systems, methods and computer program products for controlling operation of wireless network devices, such as wireless access points and wireless client devices. 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.

  • Patent number: 9429647
    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.

  • Publication number: 20160112370
    Abstract: The present disclosure discloses a method and a network device for causing client devices to renew DHCP IP addresses based on link local addresses. Specifically, the network device provides for detecting that a wireless client device has been self-assigned with an automatic IP address, and for de-authenticating the wireless client device such that the wireless client device restarts the authentication process and the DHCP process subsequently without excessive delay. In particular, the network device may receive a packet from a wireless client device. The network device then determines that a source or destination IP address of a received packet corresponding to the wireless client device is a link local IP address. Responsive to determining that the source IP address is a link local IP address, the network device transmits at least one message that causes the wireless client device to request a new IP address.

  • Publication number: 20160037458
    Abstract: 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.
