Cellular cell

Positioning technology
Cellular cell is the main location technology for GSM network to obtain location information to realize location service. It is a positioning technology based on Cell ID, which is adopted in the first phase of the wireless positioning call of E911 in the United States, and is also the most widely used positioning technology in wireless networks. This technology does not need to make major changes to mobile phones or networks, so it can build a location search system on the basis of existing mobile phones.

Cellular cell
It determines the user's location by collecting the cell identification number (Cell ID number) where the mobile station is located. As long as the system can collect the geographical location of the cell where the mobile station is located on the map and the coverage radius of the cell, the system will know which cell the mobile station is in after the mobile station is registered in the cell. The positioning accuracy of this technology depends on the radius of the cell. For example, in Beijing, the density of base stations is high, and the COO positioning accuracy can reach about 200 meters; In the suburbs, the density of base stations is low, and the COO positioning accuracy can only reach one or two kilometers.
