LPP (LTE Positioning Protocol) is a standardized protocol used in 4G and 5G mobile networks to determine the geographic location of user devices. It enables communication between the device and the network’s location server, supporting various positioning methods such as Assisted GNSS, OTDOA, and Enhanced Cell ID. LPP is essential for applications requiring accurate location data, including emergency services, navigation, and location-based services. By facilitating precise and efficient exchange of positioning information, LPP enhances both user experience and network capabilities while maintaining security and privacy standards in mobile communications.
