- yoz-y 6y agoNearby wifi hotspot location is the base for aGPS. Without it it would be slower and eat up more battery.
- TrueDuality 6y agoNo... aGPS doesn't use wifi at all. aGPS uses specific services built-in to the cellular network to accelerate your initial fix. You're right aGPS does speed up your initial time to fix so the GPS receiver doesn't have to be on as long to get an ephemeral location but other than that it doesn't have any impact on battery life such as when you're looking at Google maps with a constant fix.
- yoz-y 6y agoMy bad, I have been conflating aGPS and WPS. https://en.m.wikipedia.org/wiki/Wi-Fi_positioning_system https://en.m.wikipedia.org/wiki/Wi-Fi_positioning_system Still, phones do use hotspot location databases for positioning.
