Real Time Localization System

[oswalidos]

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.
