Hi, Any ideas how to measure wifi and BT frequency disturbances with a PDA or laptop? Is there any reasonably priced CF or PCMCIA receiver? Or just any software for Windows laptop which could scan for surrounding BT and Wifi units? The visible problem is that most of time BT mouses don't work over the range of 60-70 cm. I'd like to get a picture what's in the air around Thanks for ideas.
