The FCC recently announced new spectrum for millimeter wave. The new rules open nearly 11 gigahertz of high-frequency spectrum for mobile and fixed wireless broadband, which include 3.85 GHz of currently licensed spectrum and 7 GHz of unlicensed spectrum. This decision could prove critical for the U.S. to retain its leadership in the field of wireless communications.
Researchers at the Cockrell School of Engineering at The University of Texas at Austin have achieved a milestone in modern wireless and cellular telecommunications, creating a radically smaller, more efficient radio wave circulator that could be used in cellphones and other wireless devices, as reported in the latest issue of Nature Physics.
Bandwidth-intensive video streaming applications occupy an overwhelming fraction of bandwidth-limited wireless network traffic. The explosion of video data traffic necessitates new transmission paradigms at different protocol layers that improve video quality of experience, introduce error resilience, and meet quality-of-service (QoS) requirements. Real-time video specifically demands QoS guarantees such as delay bounds for end-user satisfaction. Due to the inherently stochastic nature of wireless fading channels, deterministic delay bounds are difficult to guarantee.
