A little over 40 years ago, I left a position at the largest, national full-service alarm company to start a long-range radio manufacturing business. I firmly believed wireless was the way of the future. The circumstances that led me to that realization are a story for another day. Certainly, the evolution of wireless technology is yet another story.

My work with wireless was directed toward UHF low-power radio for both one-way simplex and two-way polling for non-listed and listed fire and burglar alarm installations. All this was long before electronics, semiconductors and software evolved to make many things possible that I could have only dreamed about back then.
