The entire BlueTooth (BT) system is power limited for many reasons. One of them is that many devices and users have their own personal space. Given that I can see why your searches failed.

Could anyone recommend a blue-tooth transmitter? It will be connecting to an AV system in a 5 star resort, so the guest in the suite can transmit their music from their mobile device to the system. AV system is in a closet, so something with remote antennas or that can go thru the sheetrock walls and metal studs without issues.
I was thinking about putting a universal type docking station just outside of the av closet. Main issue is, walls and ceilings are up. Price is not an option! Any help would be great! Thanks!!
