Signal strength in wifi is almost completely worthless & kismet doesn't use it for anything run-time. You can try to use it from the XML for off-line plotting.

Thanks for your reply, channel model is a set of equations you use to convert a received signal strength to a distance (estimates propagation distance from signal strength losses between two terminals). e.g. HATA, SUI, ITU, etc.

So does Kismet consider time delay to estimate a position of an access point (AP) ?

Assume Kismet detected a packet from APo, can Kismet estimate the location of APo ? if yes then what measurement Kismet is using ?

Many thanks
