Your phone knows where you are before you do, and tells everyone.
means The technology that pinpoints the physical location of a device or person, usually via GPS, Wi-Fi signals, or cell towers.
from A straightforward 20th-century compound: 'geo-' from Greek gē, meaning earth, bolted onto 'location.' The prefix has a long pedigree — geology, geography, geometry all use it to mean 'of the earth' — but 'geolocation' itself is a modern coinage, born once satellites and networks made it possible to actually ask a machine 'where on earth is this?' and get an answer.
- not gps alone
- wifi and cell towers pinpoint you indoors too
- accuracy tradeoff
- gps precise outdoors, wifi faster but fuzzier
- ip based
- can guess your city from your router alone
- privacy catch
- apps ask once, then track far longer
