Abstract
Systems and methods for detecting, identifying, and locating a source of radio frequency (RF) interference are discussed herein. An interference signal can prevent a user equipment (e.g., mobile phone, smartphone, or the like) from receiving a network signal altogether, can cause a temporary loss of the network signal, can affect the quality of the network signal received, or the like. The system allows for an interference source emitting the interference signal to be detected, identified, and located so that the signal can be powered off to clear a frequency band, thereby improving network service.
Claims20
A system for identifying a source of an interference signal, the system comprising:
- a detection device including:
- a location module configured to determine a geographic location of the detection device when receiving the interference signal;
- a radio frequency (RF) power sensor configured to detect power amplitudes over a range of frequencies of the interference signal;
- and
- a processor configured to:
- compare characteristics of the interference signal to characteristics of a known signal,
- calculate a confidence level of a source of the interference signal, the confidence level indicating that the interference signal matches an identity of the known signal based on the comparison of the characteristics of the interference signal to the characteristics of the known signal,
- identify the source of the interference signal based on the confidence level, and
- output the source of the interference signal.
A method for identifying a source of an interference signal, the method comprising:
- receiving the interference signal;
- determining a geographic location of the detection device at which the interference signal is received;
- determining a signal signature based on power amplitudes of the received interference signal received over a set of frequencies;
- comparing characteristics of the interference signal to characteristics of a known signal;
- calculating a confidence level of a source of the interference signal, the confidence level indicating that the interference signal source matches a source of the known signal based on the comparison of the characteristics;
- identifying the source of the interference signal based on the confidence level;
- and
- outputting the source of the interference signal.
