You're going hiking in unfamiliar territory this weekend and have downloaded an app on your phone that shows you where you are on the map in relation to the trails and surrounding areas. Which types of location technology could this app employ?

To pinpoint the location of any device with a GPS receiver or cellular service on Earth, GPS, and cellular location services can both be used. GPS locates you by pinging satellites, whereas cellular location services rely on two or more cell phone towers. MDM is a type of data security for mobile devices, and RFID is radio frequency ID, which is frequently used in inventory management.
