是否有可能地理定位3g USB棒？ [英] Is it possible to geo-locate a 3g usb stick?

问题描述

我尝试了findmyip类型的网站，但3g usb棒的IP地址不能很好地指示设备的位置...

解决方案

这是可能的，但这取决于你的限制和路由流量由供应商完成，您愿意考虑准确的距离。如果你正在谈论街角的准确性，那么如果不使用该设备收集你周围的地标（即已知的Wi-Fi点，手机信号塔等）的信息，然后推动它信息给你。这就是 SkyHook 的工作方式。

如果您更喜欢城市或城市区域，那么您可以根据流量如何通过互联网获得良好的效果。这就是像 Digital Envoy 这样的公司提供企业级地理位置定位的数据能够以某种程度准确性。在这里准确性受到影响，因为它们的数据依赖于互联网的对等点，但它也不需要客户端设备上的软件，并且对用户来说是完全透明的。

Everything's in the question title I guess...

I tried the findmyip kind of site, but the IP addresses for 3g usb sticks are no good to indicate the device's position...

解决方案

It is possible yes, but it depends on what you're limitations are and how the routing of the traffic is done by the provider and what distance you're willing to consider accurate. If you're talking street-corner accuracy, then you aren't going to see that without using the device to gather information on "landmarks" (i.e. known wi-fi points, cell towers, etc.) around you and then pushing that information to you. This is how services like SkyHook work.

If your looking more for city or metro area, then it's possible for you to get good results based on how the traffic is routed to the internet. This is where data from companies like Digital Envoy who provide enterprise level geo-targeting can target a 3G device with some degree of accuracy. The accuracy suffers here b/c their data is relying on the peering point to the Internet, but it also doesn't require software on the client side device and is completely transparent to the user.
