Some GPS trackers do not require a wifi connection to function. Standalone GPS trackers, which are typically used for personal tracking or outdoor activities, typically use GPS satellites to determine the device’s location and store the location data on the device itself. These devices do not require a wifi or cellular connection to function, and the location data can be downloaded to a computer or other device for later analysis.

Other types of GPS trackers, such as those used for fleet management or commercial purposes, may require a wifi or cellular connection to transmit location data in real-time. These devices typically use a combination of GPS and cellular or wifi technology to determine the device’s location and transmit the data to a remote server or other device for real-time tracking. Additionally, some GPS trackers use wifi to connect to other devices, such as smartphones, to access additional features or to receive alerts. It’s best to check the specific device or service you’re interested in to see if it requires a wifi connection to function.
