Abstract
Data is collected and interpreted in response to one or more transmitted signals to determine if an interfering device is present. If an interfering device is present, a message is generated and presented to a user indicating, for example, that the installation of a micro-filter is appropriate. The system can then determine if the micro-filter was installed properly and, for example, commence communication or, if the micro-filter(s) did not solve the problem, initiate communication with or contact a technician.
Claims2
A method of detecting a device that interferes with communication signals comprising:
- transmitting a device detection signal at a frequency S;
- measuring a received signal at frequencies that are multiples of the transmitted frequency S;
- and
- detecting the presence of one or more devices that interfere with the communication signals.
