The technology that utilizes GPS for determining a user's location is mobile devices. GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on Earth. Mobile devices, such as smartphones and tablets, are equipped with GPS receivers, allowing them to access information from satellites to pinpoint their geographical position accurately.

In contrast, wired LAN connections, home Wi-Fi networks, and public IP addresses do not involve GPS technology for determining location. Wired LAN connections primarily deal with local network connectivity without any inherent geolocation capability. Home Wi-Fi networks can provide approximate location data based on network proximity, but they do not utilize GPS. Public IP addresses can give a general location based on the registered address of the internet service provider, but again, do not leverage GPS technology. Thus, mobile devices actively integrate GPS to provide precise location services, making this choice the most relevant in relation to GPS usage.
