After over 30 years, I moved from full-time work in systems engineering, enterprise architecture, and RF modeling to providing consulting services in 2014. As of 1 May 2018, I am not accepting new consulting commitments. This action provides time to teach telecommunications at Northern Virginia Community College and conduct/coordinate independent research on the effects of building materials on wireless communication.
