One of our goals here on the location team is to keep shrinking that magical blue circle that shows you where you are. In fact, just a few weeks ago, we released new optimizations for My Location that helped us calculate location even more accurately.
Today, we're taking another step toward that goal, with the release of My Location with Wi-Fi, which will provide even greater accuracy when you use a device with Wi-Fi. The premise is similar to what we do with cell tower information: information transmitted by nearby Wi-Fi access points is used to pinpoint your location. Since the range of a Wi-Fi access point is smaller than that of a cell phone tower, this often results in a much more accurate position.
Wi-Fi-based location is available in many major cities around the world, but coverage and accuracy will vary. We expect it to improve over time as more people use it.
So how can you start enjoying this Wi-Fi goodness? If you have a Wi-Fi enabled BlackBerry, please download the latest version of Google Maps for mobile. Maps for other mobile platforms, including Android, will get Wi-Fi location soon.
Wi-Fi-based location is also now available through the Gears Geolocation API, bringing more-accurate location information to the browser on your phone or laptop, including Search with My Location.
Enjoy the smaller circles!
