Hello every1 .. i am sophomore so excuse me if i ask anything stupid/obviouse. so there are allot of proximity devices but with short range so i was thinking of making one with 2.4Ghz ℝℂ tx & rx. these typicaly have range to about 1km. So all i wanna know is if there is a way to connect the arduino or sumthing to the RECEIVER at any channel or at the antenna so i can measure the strength of the signal being received from the transmitter and hence estimate the distance from the transmitter. It doesn't have to be accurate. →→→THANXX gr8 forum!!
