Telecommunication

Hi guys
Can any one suggest me some good telecommunication related projects.Please also send me the details regarding the respective projects.
Specially looking for bluetooth operating projects.I also request to send me the complete information regarding the " HOW BLUETOOTH WORKS?"
Waiting for the reply

Ah skip bluetooth that's been beaten to death. Check into some MIMO (multiple input multiple output) technology. Thats the next up and coming wireless standard.

Can any one tell me more bout MIMO (Multiple input multiple output ) technology.

First Google it on the internet so you know what you're up against. And depending on how good your math is I can either recommend some IEEE papers that started it all or explain it the best I can with most of the math excluded.
