Mainstream Use?

Unless your in an area/building saturated with WiFi hotspots this doesn't seem like it would be too useful. I just it's a niche product that would work great at corporate headquarters and hospitals, not too many other places....

Math / Geometry dictates that you must have signal to at least 3 wifi access point to get a 2-D location fix. after initial fix, the # of wifi can drop to 2. which means entire company must have double coverage (double the access point) for this to work.

the above is for 2-D fix only. to get 3-D fix (what floor you are on), we need 4 access point initially, and 3 to keep the tracking.

Yeah, but if you needed to do this, it would be dirt cheap in comparison to the other methods I can think of.

OK, forget that. The APs would be cheap. Their software is expensive. $2000 and up depending on how many devices you track.

Remember, GPS doesn't work indoors. The WiFi location system is used to locate things or people within rooms or buildings.

So, you have to have your Palm (with WI-FI)on, right? How many people are going to have their palms on continuously running wi-fi? and if they did, they would only run for like, less than an hour. This is utterly useless (especially since I don't own any corportations and have corportate employees).

What a lame development.

1. If my wife wants to locate me in the house where my home Wi-Fi is, she can yell my name; in the office my secretary does the same thing. Maybe not classy, but it doesn't need software.

2. Nobody in my firm has a T/C. We all have T/Ts. Since the geniuses at Palm/SD can't make a Wi-Fi card for the T/T, even if this swell system were to be useful, perhaps in a big company building, almost nobody can use it with a Palm.

Just so frustrating.

Wi-Fi locator? Check out this site: http://smartid.com.sg/
I purchased the WiFi locator and it works much better than the one manufactured by Kensinton.

Some people will ALWAYS be lost. No matter how high the tech, they'll always be higher!

I would think this would be better for always on Bluetooth than 802.11.

My wife has to sell a lot of candles (www.ccandles.com) to buy her new Palm.

Locator spoofer

Ok, now that someone can position you. Will there ever be any software you can put on your Palm that will counteract it being found? There are a few IR tricks for this like randomizing the lobe direction of your WiFi antenna and the packet burst rate.

The cat and mouse game is on!

Yep, you would probably want some means to override the EXACT positioning: otherwise, it would tell everyone that you are in the bathroom....and WHERE in the bathroom! OMG!

AFAIK, this needs software on the client (PDA) to work. So don't install it if you don't want to be located. You probably also have to tell it which positioning server to talk to on the client, so you pretty much know who is locating you anyhow.

Maybe this'll light a fire under SanDisk's a$$!

Wow, imagine that! An extremely useful app using a Palm device and WiFi! But what's that you say? There's only one Palm OS device supported? Well, hey, that could be a whole lot more if some hardware manufacturer got off their lazy a$$e$ and wrote a nice little device driver for the Palm OS!

Last I checked, there was something like a half dozen Sony devices as well as the HandEra 330 and TRGpro.

Maybe PalmOne needs to wake up on this too.
