  • Patent number: 11832355
    Abstract: Some embodiments include assessing multimedia service in a particular environment, determining in real-time whether an extender device would improve the multimedia service in the particular environment, and communicating a recommendation via a graphical user interface (GUI). The assessing is based on physical layer and application layer measurements of the multimedia service in the particular environment. Some embodiments utilize an application on a mobile communications device that may be used in conjunction with a multimedia device to determine placement of an extender device among multimedia devices associated with a same multimedia service customer account for a desired performance and hence, a desired customer experience.

  • Patent number: 11729707
    Abstract: In some embodiments, an apparatus includes a spectral scanning controller configured to interrupt service at a wireless access point (WAP) such that the WAP performs spectral scanning during service interruption. The spectral scanning controller is configured to interrupt service at the WAP at a first scanning frequency when the spectral scanning controller is in a first configuration. The spectral scanning controller is configured to interrupt service at the WAP at a second scanning frequency different from the first scanning frequency when the spectral scanning controller is in a second configuration. The spectral scanning controller is configured to move from the first configuration to the second configuration in response to a change in at least one of a service demand, a service quality, a spectral scanning demand or a spectral scanning quality.

  • Patent number: 11546758
    Abstract: Many customers have difficulty setting up a new extender device in the customer premises environment to improve their multimedia service. Some embodiments include configuring an extender device based on existing WiFi network credentials to minimize errors. Some embodiments include an application for mobile devices that may enable the transfer of network credentials from existing multimedia devices on the WiFi network to configure a new extender device in real time. For example, the configuration may be based on a customer account, a corresponding environment, and corresponding multimedia devices associated with the customer account. The extender device may be configured with the network credentials (e.g., a WiFi service set identifier (SSID) and password) that is common to the corresponding multimedia devices associated with the customer account.

  • Patent number: 8902777
    Abstract: In some embodiments, an apparatus includes an access point (AP) wirelessly coupled to a set of mobile communication devices. The AP is configured to determine a set of weights for a set of metrics based on a performance goal collectively associated with the AP and the set of mobile communication devices. The AP is configured to define, for each mobile communication device from the set of mobile communication devices, a maximum aggregation data unit size, a minimum aggregation data unit count, and a maximum aggregation data unit count based on the set of weights and a set of values for the set of metrics. The AP is configured to send, to each mobile communication device from the set of mobile communication devices, a signal based on the maximum aggregation data unit size, the minimum aggregation data unit count and the maximum aggregation data unit count.

  • Patent number: 5283575
    Abstract: A vehicle navigation system helps locate the vehicle on a road network by overcoming, through the use of fuzzy logic, the errors of positioning sensors and routing computers. In the system, sensors continually feed position coordinates to a processing unit that traces the vehicle's path in a road database. Fuzzy logic-based reasoning is used to determine the most probable location of the vehicle, whether off- or on-road, thereby correcting errors in its raw path as sensed or computed.
