Hi Rajmohan:

Coverage actually overlaps between cell sites.  So if a cell phone user is 
between two cell towers, both towers actually pick up the transmission. The 
towers negotiate and hand-off the call(transfer between towers) based 
on measuring the power coming from the cell phone.  The tower that sees the 
most amount of power from a particular cell phone user, by definition, must 
be the closest tower to the user, and therefore will service the user.
