This bugs me too. I have an "RFID" meeting in an hour or so to discuss an RTLS deployment using various RFID tags and RTLS transponders. The sales team has no interest in improving the management's understanding of what they're buying, only pushing product.

Just do it ++++++ I'm in the middle of nowhere so WiFi is not bothered by neighbors. It's a shared medium and multiple device drag performance down fast. I tried powerline and it worked okay--still use it in some places. Honestly, WiFi is better than power line, but it does help avoid contention. I finally had to break down and start wiring. I bought a 1000' spool and started running wires to places I wanted reliable (or high speed) connectivity. I've had to run wires in every place I've lived. CAT 6A is the long term option, if I had any chance of Google fiber coming here I'd use it. I don't. So, I went cheap with 5e. I'll forever be on 6-12 Mb (aka 18+ power boost) Comcast.
