Hot topic in digital communication

[sadid]

Hello!
I want to give a presentation for my Advanced Communication course.
I want a hot and new topic in the field like CDMA,UWB,Cognetive Radio,WiMAX,... but more newer than these and a bit less general and big topic (like spread spectrum or CDMA sth like OFDM for example,....) do you have a better topic than these to offer?

Thanks.
