Abstract
In one embodiment, an apparatus for minimizing signal interference for a network device is provided. The apparatus includes a receiver configured to detect an interference signal. The apparatus also includes a signal analyzer that is configured to analyze the detected interference signal. The apparatus further includes an interface. The interface is configured to advertise detection of the interference signal as a service offered by the apparatus to the network device. The interface is configured to accept a request from the network device to subscribe to the service. The interface is also configured to alert the network device when the interference signal is detected.
Claims20
An apparatus, comprising:
- a receiver configured to detect an interference signal;
- a signal analyzer configured to analyze the detected interference signal;
- and
- an interface configured to:
- advertise detection of the interference signal as a service offered by the apparatus to a network device;
- accept a request from the network device to subscribe to the service;
- and
- alert the network device when the interference signal is detected.
A system, comprising:
- a receiver configured to detect an interferer;
- an analyzer configured to analyze the detected interferer and submit a recommendation for a selected one of a plurality of network devices on a network based on the analysis;
- and
- a controller interface configured to:
- advertise to the network a list of services offered by the system, the detection of the interferer being one of the services;
- allow the network devices to selectively subscribe to the list of services;
- broadcast the detection of the interferer as an event to the network;
- and
- send the recommendation to the selected network device.
A method, comprising:
- advertising a capability to detect an interference signal as a service to a network;
- accepting a request from a device on the network to subscribe to the service;
- detecting the interference signal;
- analyzing the detected interference signal;
- and
- broadcasting the detection of the interference signal as an event to the device.
