CET was founded in 1984 by Bill and Nancy Davis who wanted to revolutionize the way in which radio frequency sites were designed, planned and licensed. Although they had both worked extensively in the industry it was not until CET was formed that their ideas became reality. Since that time CET has grown and helped to design, plan, and/or license over 650,000 sites all over the world.

Today CET is one of the leading providers of wireless planning, licensing software applications and related services. CET's technology and services are designed to more efficiently plan and license wireless sites whether their use is Wireless Internet, PCS/Cell, Public Safety or other Land Mobile Radio. CET is also currently the only provider that can take your site from the design stages to approval by the FCC as we maintain the central computer network and software of the majority of FCC approved Frequency Coordinators.
