This application focuses on the 14 key equations in the IEEE WCET certification exam glossary (as can be found in the WCET handbook available for free upon request, from IEEE Communications Society). The aim is to help the user to understand the equations. The user can then take the exam, or perform other work in the wireless field, with more confidence.

Features of this application include:
- beautiful, LaTeX-rendered equations
- improve your feel for each equation by trying it out with different values. The settings of the values of the variables is very naturally done through sliders
- a notes section commenting on each equation, pointing out how it is used, and other related information

This application is excellent value for money, when compared with other resources for WCET exam preparation, such as the following (as checked in September 2012):

a) books like the WEBOK, Fundamentals of Wireless Communication Engineering Technologies, etc., selling for $65-$130

b) WCET practice exam with 75 questions, from IEEE, for $50
