I keep hearing that bluetooth is only good for 30 feet, but look at
these:



The last time I looked there were 3 standard ranges of bluetooth.
Less than 1 meter, less than 10 meters, and 100 meters.

I never heard about the short one either. I must live in a cave.

There are some range extenders for BT, but I have not looked into them
as I do not do anythig with BT over 10 meters.
