Final answer:
Cell networks and Wi-Fi hotspots can be used to determine location through triangulation. Cell tower triangulation estimates location based on signal strength from different towers, while Wi-Fi hotspot triangulation analyzes signal strengths of nearby Wi-Fi routers.
Step-by-step explanation:
The use of signals from the cell network or Wi-Fi hotspots to determine location is a common practice in today's technology. Both cell networks and Wi-Fi hotspots can be used to triangulate a person's location.
When a cell phone connects to a cell tower, it provides the tower with unique identifiers, and the tower can estimate the phone's location based on the signal strength received from different towers. This method, known as cell tower triangulation, can provide a general idea of the phone's location within a few hundred meters.
On the other hand, Wi-Fi hotspots use a similar concept by analyzing the signal strength of nearby Wi-Fi routers. By comparing the received signal strengths of multiple routers, the device can estimate its approximate location.
