Basically, when you make a call, signal goes from phone to cell site/tower, to a "switch," which sends the call to intended target. #Bosma

As explained earlier in trial...Urban areas have more cell towers each with lesser coverage. Rural areas = Fewer towers with more coverage.

Place call, goes to cell site, then switch, then recipient. Switch gathers billing info: to & from numbers, voice or text, duration, tower.

Phone uses cell site with strongest signal. So usually closest tower is pinged. #Bosma

Fortier says two ways to track a phone's location. If it's on they can "ping" it and get a general latitude & longitude. #MillardSmich

If a phone is off, they have to rely on most recent call records. #MillardSmich

If phone is on, can ping it to get its latitude/longitude. If off, can get last cell site. #Bosma

Large buildings can onstruct radius/signal of a cell tower. So can heavy use of cells in area and weather. #MillardSmich
