Excellent, this was just what I was looking for. I found lots on DIY wireless stuff but nothing on the real deal till I found your course. Perfect, thanks.

Hi, Just to let you know this is very good, a lot of detail in the book. It really made it all clear for me. I'm installing an alarm in my house now.
