Enhanced Cell Identity (E-CID)

Enhanced Cell Identity uses a combination of angular information (the cell sector receiving the signal) and timing information to approximate the location of the handset. Similar to Cell Identification, E-CID fixes the location of the user by identifying which cell in a network is carrying the user’s call and translates that information into latitude and longitude. Best used in less dense spaces, E-CID is little more accurate than Cell ID but has the capability of extending to less serviced rural areas.
