radio

问题 Is there is a way to determine an iPhone's exact location (indoors, and to a distance of just a couple of feet) via use of radio/antenna's or some other infrastructure located around premises (i.e a hospital, shopping mall, school). Will appreciate any ideas/direction (technologies, research) as for how to overcome this limitation. 回答1: If you mean for an area you have control over (setting up a location network for a specific school/hospital) as opposed to generic location, you'd be able to

问题 The question sums it up ... Here's what I've tried, is there a better way?
