This can be done using various techniques such as through radial distance, direction or receiving a signal from two to three different points and then assessing the exact location by overlapping of the three radial distances. Triangulation in cellular communication is commonly used to pinpoint the exact geographical location of a user.

Techopedia Explains Triangulation

Triangulation is widely used in wireless mobile communication to find the location of a cell phone user. Triangulation is utilized in cruise navigation, radar systems, GPS systems in vehicles and other such mobile devices. It plays an important role in emergencies and vast setups like 911 are based on triangulation strategy of locating the location in question. A triangulation mechanism can be affected by the presence of steel structures, water towers, communication posts and signal jammers. Using two or more points to determine the location of radio transmitter or cell phone user give much more reliable results than relying on just one.
