Pi in the Sky, Part 1: WLAN Pi Basics

For some Wi-Fi professionals, WLAN Pi is the ultimate swiss army knife. For others, it is a byzantine puzzle.  Your humble blogger takes great pride in taking the complex and making it accessible. For the WLAN Pi, it starts with the Basics. The WLAN Pi project has been part of the WLAN professional community for several years.
