If you’ve ever used an older GPS device before you might have noticed that it takes time for the GPS signal to lock on. This is known as a cold start, and can range anywhere from 20 seconds to a minute or so. With today’s mobile devices that have mobile data, this time can be cut down substantially by employing Assisted GPS (AGPS), which uses cell tower location and/or wifi network location to help locate you faster. On an Android device (and most mobile devices), this results in location finding from cold in a matter of seconds, anywhere from 2 seconds up to around 15-20. Do note that this will may use some mobile data, but this is generally extremely miniscule.
Here’s how to enable AGPS on an Android device:
- From Home => Settings => Location & Security
- Use Wireless Networks => On
- From here on, your location based programs which utilise GPS (Maps, Places, etc) will use AGPS.
