Detection 3: Changing Signal Strength

Created by: E3V3A

A rapid change in signal strength when phone is not rapidly moving or "accelerating" and when the currently connected technology (LAC/CID/channel etc) remains the same, would indicate an abnormal and suspicious behavior.

However, a changing signal strength is a very bad indicator all by itself, at least for any phone not laying perfectly still, with people around staying perfectly still, which is a very unlikely scenario. Just waving your hand in front of your phone laying on a table can easily change the received signal strength.

Thus signal signal strength will not be used alone, but in combination with other variables.

Device dependence.

Unfortunately signal strengths is device dependent and thus pretty useless, apart showing your signal bars. In order to make any use of this, a relative signal strength may be more appropriate, where relative changes of several dBm would be more interesting.
