RadioHound: A Low-Cost Spectrum Sensor

Dr. Hochwald
Principal Investigator: 

Dr. Hochwald, Department of Electrical Engineering. This project also involves Drs. Laneman and Chisum, of the Department of Electrical Engineering, and Dr. Striegel from the Department of Computer Science and Engineering. Also, assisting with this project is Scott Null, Senior Research Software Engineer.

Project Summary: 

RadioHound, an ongoing project at NDWI, is the development of low-cost, portable spectrum measurement sensors capable of tuning over a wide range of frequencies commonly used by everything from cellular phones to wireless local area networks, to radios and televisions. One goal is to distribute these sensors over a wide geographical area and thereby crowd-source the real-time measurements to create a “heat-map” of spectrum usage over the area and across frequency. Such a map would be used, for example, to determine where spectrum congestion is dense.

We are in the fourth year of this project.

Student's Role:

The project has many hardware and software components and opportunities for students to contribute, depending on their technical software and hardware maturities and skillsets. Basic hardware and laboratory capabilities, and knowledge of C, Python, and networking are a plus, but not required.

In particular, we have openings for: (1) laboratory measurement help with the experimental verification of heat-maps that are generated by these sensors. Hence, knowledge of laboratory equipment and practices is advantageous; (2) web-application software development to help with displaying and controlling various aspects of the RadioHound system. Hence, knowledge of web development is advantageous.
