【Google】 Mobile Search with My Location now with Wi-Fi

Gears Geolocation APIが無線LANからも位置情報を取得できるようになったらしい。

Official Google Mobile Blog: My Location now with Wi-Fi
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.

世界の主要都市に居ないから確認できませんが・・。(´・ω・｀)

前回はGoogle(英語版)上に位置表示されていたはずが・・表示されなくなっています。

Gearsのバージョンは 0.4.20.0→0.4.24.0へ。

Gears API Blog: WiFi-based geolocation, anyone?
Guess what? The Gears Geolocation API got even better! We have just released a new version of Gears, 0.4.24.0, which contains an enhanced implementation of the Geolocation API. This new version uses WiFi access point signals to return significantly more accurate results, making it a lot more useful on laptop computers.

ChromeやAndroidはGears内蔵だからインストール不要とか。

そういえば、Android携帯「T-Mobile G1」は本日発売ですね。
国内キャリア各社の秋冬新製品発表会が来週あたりから始まるそうなので
特にスマフォ関係に注目してみたいと思います。
