Question : Measuring distance with wireless

I need to find a wireless technology which can be used to guage distance between 0 and 100 feet.  I imagine that that's the upper range for Bluetooth.  But can I use Bluetooth or any other wireless technology to tell me is somethin is 20 feet away from a receiver (or transmitter) or 40 feet away?

I am very interested to know. So please say so if you any anything about how to do this.

Thanks,
