Just want some advise we have a couple of meeting room's with Microsoft Wireless Mulitmedia Keyboard 1.1 (Microsoft Wireless keyboard 1000) however the range on these seem rather poor. So I thinking of investing in something abit better. I wanted to know though for meeting room's not too big maybe 50x30ftt what is the better technology Bluetooth and Wireless Keyboard. Is their a significant difference between them.

My limited understanding is that Wireless keyboards operate at low frequency and Bluetooth operates at high frequency
