Someone says below:<snip> I've used some here in India > but most of the times I never got any valid GPS signals at all, which force > me to use Internet connection.</snip> GPS signals are provided by satellites that are equally available in all parts of the world. http://en.wikipedia.org/wiki/Gps At any point in time, you need to see 4 gps satellites in the sky to start, which can go down to 3 once you have an initial location fix. So, your feeling that you get a better gps signal in the US or UK than in India is a misconception. Also, internet connectivity is required by most mobile based map providers, including wayfinder/nokia/google and that is what uses internet much more than a-gps. Internet connectivity on mobile phones is actually many times cheaper in India as compared to the US. I have a fixed cost of rs. 99 on my airtel connection for a month for about 50 MB (which I never use up with gps alone) while it was about $40 a month on AT&T when I was in the US.
A-gps is actually very helpful in getting a quicker initial location fix or for continuing navigation in patches where enough satellites may not be visible for some reason. Finally, if you have enough detailed maps, gps devices are just as successful, if not more, in India as anywhere else in the world and I can say that based on my daily usage here in Delhi and in other parts of the globe. -Manish -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of himalaya singh Rawat Sent: Sunday, February 21, 2010 8:02 AM To: [email protected] Subject: Re: [AI] accessible gps comparison hello pranav, you are right. wayfinder access is needed but seeing the current market situation i doubt vodafone will revive it. nokia has freed its map and it works good. the only this is that it has to be made accessible.
