Geolocation造句怎么写

让我们回到去年的黑莓开发者大会会场，ResearchInMotion小组展示了一款当时还未发布的叫Geolocation的新功能。

The Geolocation service USES cell towers to gather quick location information and deliver it to applications on BlackBerry smartphones.

Geolocation coverage will extend from hiking trails and sea-lanes all the way downtown, indoors and into areas that are currently plagued with weak reception, such as under tree limbs.
