Re: How to Calculate Distance Between Cell phone/GSM modem &
Theorically, you can calculate the distance by the Friis equation in free space, supposed that the gain of the cell phone antenna and the BTS antenna is given, then you can get the distance by the Friis equation. But in practice, because the effect of multi-path transimission, you can hardly get the distance accurately.
