| signal distance
| the distance that a wireless signal
traveled from a transmitter to a receiver
|
|
signal distance could be estimated by comparing the strengths of
the trasnsmitted and received signals based on a signal
propagation model

|
r1', r2', r3' are the (estimated) signal distances from x to AP1, AP2, and AP3, respectively
|

|
Calculate the postion of x based on the postions of AP1, AP2, and AP3
as well as r1', r2', r3' may be very inaccurate
