Abstract
In some implementations, the method may include receiving an RF signal of the RF link by an antenna interface of a primary radio device. In addition, the method may include performing spectral analysis with the received RF signal, where harmonics of the received signal are searched. The method may include, in a case that harmonics are detected, determining a fundamental frequency of the RF signal from a spacing of the determined harmonics. The method may include classifying the RF link based on the determined fundamental frequency.

A method of classifying an RF link, the method comprising:
- receiving an RF signal of the RF link by an antenna interface of a primary radio device;
- performing spectral analysis on the received RF signal including determining harmonics of the received signal;
- wherein, in a case that harmonics are determined:
- determining a fundamental frequency of the RF signal of the RF link from a spacing of the detected harmonics;
- and
- classifying the RF link based on the determined fundamental frequency.
A non-transitory computer-readable medium storing a set of instructions for classifying an RF link, the set of instructions comprising instructions that, when executed by a processor of a device, cause the processor to:
- receive an RF signal of the RF link from an antenna interface of a primary radio device;
- perform spectral analysis on the received RF signal including determining harmonics of the received RF signal;
- and
- wherein, in a case that harmonics are detected, the instructions cause the processor to:
- determine a fundamental frequency of the RF signal of the RF link from a spacing of the determined harmonics;
- and
- classify the RF link based on the determined fundamental frequency.
A detector device for classifying an RF link, the detector device comprising one or more processors configured to:
- receive an RF signal of the RF link from an antenna interface of a primary radio device;
- perform spectral analysis on the received RF signal including determining harmonics of the received RF signal;
- wherein, in a case that harmonics are determined:
- determine a fundamental frequency of the RF signal of the RF link from a spacing of the determined harmonics;
- and
- classify the RF link based on the determined fundamental frequency;
- and
- wherein in a case that no harmonics are detected, the one or more processors are configured to classify the received RF signal of the RF link as an in-band signal.
