Impulse radio ultra wide-band (IR-UWB) is gaining traction for use in indoor positing and tracking. Two French entities--BeSpoon, a fabless semiconductor company, and French research-and-technology organization CEA-Leti--said they have demonstrated an IR-UWB integrated circuit able to measure distances within a few centimeters' accuracy.

The University of Melbourne issued a surprising analysis that indicates "inherently energy inefficient" radio access networks are "the biggest threat to the sustainability of cloud services."

Client-side software developed by researchers at the University of Michigan has been shown to control the onslaught of mobile data traffic and reduce interference among devices using Wi-Fi, Bluetooth and Zigbee.
