I was thinking about different ways to make a 'police detector' and I realized that more signals are given out then just radar/laser and radio waves for talking. They have computers in their car that upload data constently to sites like http://cad.chp.ca.gov/ so there must be some sort of way to detect these things. I'm curious what type of waves are given out and at what frequency. Is it GSM or EVDO? I don't know if someone can use a scanner to locate where a phone is. I would love to learn about all of this even if it will not go anywhere.
