Hello everyone. I'm wondering about the effectiveness of bluetooth for wireless keyboards and mice. In one of our conference rooms we have an A/V system that includes a PC. The PC is inside a cabinet on the floor. The door to the cabinet is always closed. I'm wondering if I were to get a bluetooth wireless keyboard/mouse combo in which I plug a bluetooth adapter into a USB port on the PC are the odds good or bad that the signal strength will be sufficient to make it through the cabinet door, as well as through the person sitting at the table using the wireless keyboard/mouse? Any thoughts?
