Abstract
Methods and systems for network jamming detection and remediation are provided. Exemplary methods include: detecting by a base unit network jamming, the base unit being disposed in a residence; and issuing an alert in response to the detected network jamming, the alert being last least one of: sounding an audible alarm, showing a visual alarm indication, communicating with law enforcement, and communicating with an alarm monitoring station.
Claims20
A method for network jamming detection and remediation, the method comprising:
- detecting network jamming, wherein the detecting occurs by a base unit disposed in a residence, the detecting the network jamming includes:
- measuring, using a radio, a signal strength over a slot time and over frequencies of a wireless network;
- and
- identifying the network jamming when the signal strength exceeds a predetermined threshold;
- and
- issuing an alert in response to the detected network jamming, the alert being at least one of:
- sounding an audible alarm, showing a visual alarm indication, communicating with law enforcement, and communicating with an alarm monitoring station;
- buffering the alert when the alert cannot be issued due to the network jamming;
- and
- issuing the alert when the network jamming has ceased;
- wherein the base unit is coupled to at least one local area network (LAN) in the residence, is coupled to a wide area network using a broadband interface at the residence, and includes at least one of a radio for a wireless network radio and an interface to a wired network.
