A plain-language explanation
Geolocation is the determination of the approximate or exact location of a device based on GPS, cellular network, IP address or available wireless networks.
Where it helps in practice
Geolocation adapts content or service to place, but accuracy depends on consent, device and signal source.
The decision before implementation
Decide whether country, city or a precise point is necessary and design a useful fallback when access is denied.
How to verify the result
Test wrong detections, VPN use, area boundaries, privacy and manual location correction.
