A paper published by Swinburne University of Technology shows how a kind of "optical ruler," or frequency comb, can greatly increase bandwidth in today's data-saturated world. Integrated optical frequency comb sources, or microcombs, have driven major advances in spectroscopy, metrology and more. Their potential in data transmission is especially promising, exceeding speeds of one petabit per second—10 million times faster than a 100Mbit/s NBN connection.

Live and on-demand video constituted an estimated 66% of global internet traffic by volume in 2022, and the top 10 days for internet traffic in 2024 coincided with live streaming events such as the Jake Paul vs. Mike Tyson boxing match and coverage of the NFL. Streaming enables seamless, on-demand access to video content, from online gaming to short videos like TikToks, and longer content such as movies, podcasts and NFL games.

The evolution of wireless communications and the miniaturization of electrical circuits have fundamentally reshaped our lives and the digital landscape. However, as we push toward higher-frequency communications in an increasingly connected world, engineers face growing challenges from multipath propagation—a phenomenon where the same radio signal reaches receiving antennas through multiple routes, usually with time delays and altered amplitudes.

Researchers from TU/e have transmitted data between the TU/e campus and the High Tech Campus over a 4.6 km distance using infrared light. This happened at the astonishing rate of 5.7 terabits per second, the equivalent of streaming 1.9 million Netflix shows in HD simultaneously. This is the fastest wireless data transmission ever demonstrated over this big a distance in an urban setting.

Global mobile communications that reliably reach every remote region, leaving no gaps on the map? Satellites play a key role in achieving this goal. In the future, however, not all satellites will be powerful enough to act as complete base stations. As part of the TRANTOR project, Fraunhofer IIS has now researched a splitting method that allows satellites of different classes to be integrated into the 5G network despite that shortcoming.

An estimated 240 million calls are made to 911 in the U.S. each year, with wireless devices accounting for 80% or more of these calls. Making sure emergency calls connect and stay connected to 911 dispatchers is essential and could have life-threatening consequences. MSU researchers found that in certain situations, 90% of emergency wireless calls failed to connect to 911 within 120 seconds but have developed an app to correct this.
