You...I use cell broadcast information (channel 50). You're right, it's not very reliable (ads etc.) and the location names vary with the service provider. I was just too lazy to find how to read the tower id :)<BR/><BR/>Using google's service would require internet connectivity - something that I didn't want to mandate.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7343912.post-35867331723470100232008-12-13T15:02:00.000+05:302008-12-13T15:02:00.000+05:30mm interesting.

Depending on cell-broadcast information (btw which channel do u use?) is risky because it looks like the service providers are not bound to broadcast tower information. Once I saw vodafone publishing ads through cell broadcast in madurai network. <BR/><BR/>Using the cell phone's tower-id obtained through the underlying OS APIs might be more practical; given that you want the user to give the name of the towers, it should be good enough.<BR/><BR/>Are you aware of the google maps AGPS? where they provide an approximate geographical location based on your tower id? I use this when it is difficult to get the GPS signal inside closed areas (sometimes in train). They have a really huge database of the towerids mapping to geographic locations.Gerald Naveenhttps://www.blogger.com/profile/18255818071617217134noreply@blogger.comtag:blogger.com,1999:blog-7343912.post-44337354298330803272008-12-13T13:33:00.000+05:302008-12-13T13:33:00.000+05:30"When I usually travel by train, ... specially use..."When I usually travel by train, ... specially useful when its dark outside and is difficult to guess the place from the upper berth."<BR/><BR/>I wrote something very similar that uses cell tower information rather than GPS, primarily because my phone doesn't have GPS :).<BR/><BR/>http://msmvps.com/blogs/senthil/archive/2008/07/02/wami-0-1-released.aspxAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7343912.post-58665821560207385702008-12-10T11:01:00.000+05:302008-12-10T11:01:00.000+05:30true. once we start using it, we would realize so ...true. once we start using it, we would realize so many uses of it. <BR/><BR/>However, I should admit that, at least as of today, GPS is not a must-have-gadget.Gerald Naveenhttps://www.blogger.com/profile/18255818071617217134noreply@blogger.comtag:blogger.com,1999:blog-7343912.post-57492428540855514732008-12-10T02:42:00.000+05:302008-12-10T02:42:00.000+05:30that was nice.. so many utilities !!!!that was nice.. so many utilities !!!!யாத்ரீகன்https://www.blogger.com/profile/10770053111944621915noreply@blogger.com
