  • Patent number: 10009795
    Abstract: A web-based radio survey service is provided to client devices. The client devices individually conduct a radio survey. The radio surveys are sent to a central server for analysis. The central server evaluates the radio surveys and determines a least congested radio channel for common use by all the client devices. The client devices may thus all switch to the least congested radio channel to ensure reliable radio service with an access device.

  • Patent number: 7983179
    Abstract: A system for collecting data from a communications network includes customer premises equipment (“CPE”) for monitoring and storing response data. A CPE data collection module uses a Web-based service to collect information from the CPE and process the information to determine line quality and any errors that may exist on either the WAN side or the LAN side of the communications network, and further determine the root cause based on built-in business rules for trouble shooting customer service. The CPE conducts per-tone diagnostics on the WAN side of the communications network and obtains WAN side data. The CPE obtains response data from devices on the LAN side. Both WAN side data and LAN data may be transmitted substantially in real-time or stored and transmitted periodically to the CPE data collection module upon requests originated from the CPE data collection module.
