I was wondering about the the ability of the antenna of mobile to transmit the signals to the BTS. It is known that the BTS uses high powers to provide its antennas with large distances of signal transmissions (more than 20 km ) so that we see that one BTS can cover very big area with a huge number of mobile stations and hence transmits its signals to all the mobile stations, but in the opposite case when the mobile try to transmit its signals to the BTS and the distance between them is very big (say more the 10 km), how can the antenna of mobile station transmit its signals with very small power taken from the mobile battery?
