Is this project for Amateur Radio Operators only?
This project is not exclusively for Amateur Radio Operators but because they are licensed to use a wide variety of equipment and frequencies Amateur Radio Operators can utilize more of the features than say someone using FRS/GMRS or other unlicensed radios.
Check out http://www.arrl.org/ to find out how to become a Licensed Amateur Radio Operator.
Also, there are a great number of commercial applications for this technology and Xelatec provides professional products and services to support those applications.
