@H1000 posted:Pretty much every version of bluetooth had good range if it was outputting the right amount power. I have bluetooth 2.1 devices that easily make 500 feet and almost a 1000 if they have external antennas.
The main focus of newer versions of bluetooth isn't really range but throughput.
Obviously, for 99% of the viewing audience here, modifying their BT devices is out of the question, so they go with what Lionel makes. That limits the range to a pathetic 20 feet or so.
