Real Time Localization System

Since i prefer c++ to java and other programming langages, i'd like to use Qt to develop a (Real Time Localization System) RTLS using WiFi for a particular architecture.this will be my final project to get my diploma in computer engineering.
actually this software should be developed for PDAs.

my research's results during a couple of days are :
-there is a software made by Ekahau in java.
-there is an API called Ekahau SDK for java developers .
-a similar project was made by c# .

questions :
1)how Qt helps me to develop PDA applications? QtExtented ? please more informations
2) is Qt able to manage (wifi equipements, 802.11 protocol) ?
3)for a beginner(a student yet, u know !), is it feasible to develop such application in four or six mounth ?
4)is it feasible to create a middleware for my needs of networks ?
5)this kind of application is not yet developed using Qt, am i right ?

keywords : RTLS, wifi, WPS, Ekahau SDK

here is a description of a project like i want to develop.

Best regards,
walid.

I may be wrong. If so please correct me.

1) The current Qt packages support development for Embedded Linux and WinCE.
2) No, this is a task for the operating system and device drivers.
3) I think it is feasible. Qt has a very steep learning curve, meaning you learn very fast a lot of things. Of course it requires to read and try out a lot, but compared to other libraries Qt is very easy to learn.
4) Not a clue. I don't even know what a "Real Time Localization System" is :). Something like car navigation devices does? But without the route finding?
5) Maybe someone has, maybe not. I don't know.

thanks for your answer :)

1) i have never developed embedded application,so can you please give some links to get started (french or english) ?
2)absolutly, OS take care of protocols and so on but i asked if Qt have some packages for network to manipulate easily wifi?
3)i'm agree with you,i already tried it in a project as just a GUI, but i didn't use embedded or network classes.
4) yes , it's like GPS with cars, but it's for an exiting wifi infrastucture,for exemple to localize my PDA in my university,and find the route to my classroom,it have many advantages.

if you want try to make a little research on www.pdf-search-engine.com with keywords i wrote and you'll find many publications about that topic.

(Enumerations are pretty cool :))

1) The Qt documentation should have everything you need: http://qt.nokia.com/doc/4.5/index.html -> Qt for Embedded Platforms
2) WiFi (i.e. IEEE 802.11) specifies the physical layer. So everything above (most communication is done via TCP/IP, as you know) can be done with the QtNetwork module.
