My areas of expertise are telecommunications, radio-location, radio-navigation, cellular networks, and cellphone intercept and tracking systems. I have more than 20 years of experience practicing in these areas in both civilian and government applications.

I was the primary author of OpenBTS, a very widely used tool for cellular technology education, cellphone testing, cellular security research, and basic cellular service in some public networks. I developed the signal analysis and target location algorithms and software for cellphone tracking systems used successfully by US special forces in combat operations.

I have also worked on several US government projects in the area of telecommunications intelligence collection. I also operate a company that provides mobile network equipment and test equipment for small network operators, embedded systems developers, and special applications.
