Hi, i'm not very up to speed with this kind of technology and need some help.....

Is it posible to have a bluetooth main server, with multiple transmitters scattered about a local area/work site, that you can move between without having to reconnect. What i want is to stay located to the main hub, but be able to move around. Is it posible with bluetooth, or is it posible with wifi (if so how?)

Any advise would be great, or any places to look for references.

Also if i wanted to write a program for a mobile phone what software should i use? and where can i get it from?

Thanks again
