Calculate distance from BTS to UMTS & LTE EVB KIT (module BG95)

Hi All,
I found the cell id and Rx level of the nearby BTS but I don’t know how to calculate the distance from the BTS to my module.
Please help me solve this problem!
Thank you!

As FAR as I know, you can’t calculate this distance;
How do you know how to calculate distance?

Have you caculated it yet? how do you find BTS on module BG95?
