Lowering power consumption while improving functionality is the new Holy Grail for consumer technology designers. This is especially true in areas like wireless devices where gadgets such as mobile phones and tablets continue to shrink in size, yet are expected to perform more and more functions. Being able to reduce...

Graphennas – a seemingly far-fetched idea of tiny antennas composed of graphene – are one step closer to revolutionizing nanotechnology thanks to recent tests published in IEEE Transactions on Communications. Or at least, they’re one step closer to reality. While the hypothetical concept of graphennas has been introduced in...

In the world of wireless communications, the concept of the buffer-aided relay usually generates interest because some believe it could improve connectivity and eliminate the familiar “sorry-can-you-hear-me-now?” moments resulting from weak signals. But could it also hold the key to more-secure communications? In a paper recently published in IEEE Transactions ...
