About a year ago, a friend and I canvased the island of Manhattan with a GPS mapping out hotspots, and sure enough we were able to make a reverse lookup directory based on MAC addresses.  Caveat: when an access point moves, your 'map datum' changes.  Hence, this technology will never even come close to paralleling GPS.  GPS, in fact, is already a watered-down technology.  The US Government restricts consumers from using the full power that the GPS offers because they fear that if the GPS units are too accurate, they could be used in home-brewed guided missiles or other nasty devices.  In any event, this isn't news.  http://www.INeedAttention.com staff did it first.]]></description><dc:creator><![CDATA[http://www.INeedAttention.com/ Staff]]></dc:creator><pubDate>Dec 19th 2005 2:39AM</pubDate></item><item><title><![CDATA[Comments on Find your way with WiFi]]></title><link>http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</link><guid isPermaLink="true">http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</guid><description><![CDATA[This is a very big topic for research atm.  USCD have had ActiveCampus running for a while now (http://activecamous.ucsd.edu).  I created an indoor/in office system as part of my undergraduate degree (http://emhain.wit.ie/~p02ac03/cpinfo.html).  MS Research created a system called RADAR (http://research.microsoft.com/~padmanab/papers/infocom2000.pdf).<br><br>Could lead to some really amazing location based games, have a look at Pirates! (http://play.tii.se/projects/pirates/pirates.html)<br><br>:-)]]></description><dc:creator><![CDATA[Andrew]]></dc:creator><pubDate>Dec 19th 2005 2:39AM</pubDate></item><item><title><![CDATA[Comments on Find your way with WiFi]]></title><link>http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</link><guid isPermaLink="true">http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</guid><description><![CDATA[With Metricom's Ricochet network there were similar applications years ago. Made even easier by the fact that a central system operator deployed all nodes and knew their exact location quite precisely. Glad to see it getting there with WiFi, but now with actual GPS chips getting quite cheap it seems that vice versa might be more useful... use your known location to tell you how many feet to move in what direction to get online.]]></description><dc:creator><![CDATA[Raines Cohen]]></dc:creator><pubDate>Dec 19th 2005 2:39AM</pubDate></item><item><title><![CDATA[Comments on Find your way with WiFi]]></title><link>http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</link><guid isPermaLink="true">http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</guid><description><![CDATA[We've been working on a Wi-Fi positioning system too. (http://www.herecast.com/)... the aim of this one is to make it easy for developers to create location-aware services. (As far as I'm aware, RADAR by Microsoft was actually the first.)]]></description><dc:creator><![CDATA[Mark Paciga]]></dc:creator><pubDate>Dec 19th 2005 2:39AM</pubDate></item><item><title><![CDATA[Comments on Find your way with WiFi]]></title><link>http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</link><guid isPermaLink="true">http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</guid><description><![CDATA[The signal strength can be a reasonable indicator of distance from an access point. It can also be a rough indicator of direction if you have a map physical area of coverage. The more access points in the vicinity, the higher the positional resolution. Of course, it gets better if you know what WiFi hardware the client is using! Using a WAP and a bridge, I've been very accurate in locating a mobile card in a 50m WAP radius. I just need simple (I can imagine) software to log, map and visualize locations.]]></description><dc:creator><![CDATA[Geoff]]></dc:creator><pubDate>Dec 19th 2005 2:39AM</pubDate></item><item><title><![CDATA[Comments on Find your way with WiFi]]></title><link>http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</link><guid isPermaLink="true">http://www.engadget.com/2004/06/30/find-your-way-with-wifi/</guid><description><![CDATA[I think GPS is stil better]]></description><dc:creator><![CDATA[hall]]></dc:creator><pubDate>Dec 19th 2005 2:39AM</pubDate></item></channel></rss>
