Literally.<\/p>\n<p>Ultrahigh frequency bandwidths are easily blocked by objects, so users can lose transmissions walking between rooms or even passing a bookcase.<\/p>\n<p>Now, researchers at Princeton Engineering have developed a machine-learning system that could allow ultrahigh frequency transmissions to dodge those obstacles. In an article in <i>Nature Communications<\/i>, the researchers unveiled a system that shapes transmissions to avoid obstacles coupled with a neural network that can rapidly adjust to a complex and dynamic environment.<\/p>\n<p>Lead researcher Yasaman Ghasempour, an assistant professor of electrical and computer engineering at Princeton, said the work is an important step toward deploying data transmission in the sub-terahertz band, which is at the <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.ericsson.com\/en\/6g\/spectrum\/sub-thz\" target=\"_blank\">upper end<\/a> of the microwave spectrum.<\/p>\n<p>Transmissions in the sub-terahertz band have the potential to handle 10 times the data of current wireless systems. This kind of fast transmission would be important for uses such as virtual reality systems or fully autonomous vehicles.<\/p>\n<p>&#8220;As our world becomes more connected and data-hungry, the demand for wireless bandwidth is soaring. Sub-terahertz frequencies open the door to far greater speeds and capacity,&#8221; Ghasempour said.<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Sub-terahertz_beams_are_easily_blocked_but_can_bend_with_special_transmitters\"><\/span>Sub-terahertz beams are easily blocked, but can bend with special transmitters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Ultra-high frequency signals like those in the sub-terahertz band are transmitted in defined beams, unlike lower frequency radio waves, which can span over wider areas. This makes the signals easy to block, particularly indoors and in areas with lots of moving people and objects.<\/p>\n<p>Engineers have successfully tested systems using reflectors to bounce signals around obstacles. But these systems rely on reflectors that may not be available or practical in many situations.<\/p>\n<p>Ghasempour&#8217;s team proposed using a special transmission technique to dodge obstacles. The researchers were able to bend transmission beams by transmitting a signal that curves around the obstruction. In doing this, they used an idea first proposed in 1979 for a kind of radio wave called <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/nphoton.2011.80\" target=\"_blank\">Airy beams<\/a> that allow engineers to shape transmissions like a curveball. When correctly controlled, the beams can maneuver through a complex and moving field of objects.<\/p>\n<p>&#8220;This is for complex indoor scenarios where you don&#8217;t have a line of sight,&#8221; said Haoze Chen, a graduate student at Princeton and the paper&#8217;s lead author. &#8220;You want the link to adapt to that.&#8221;<\/p>\n<p>Unlike static systems, the new system allows the transmitters to adapt to changes in real time.

The standard method of aiming beams\u2014scanning a room for the best transmission path\u2014does not work for bendable transmissions.<\/p>\n<p>&#8220;For Airy beams, this is impractical,&#8221; Chen said. &#8220;There are infinite ways of curving depending on the degree of the curve and where the curve happens. There is no way a transmitter can scan through.&#8221;<\/p>\n<p>To solve the problem, the researchers took a cue from human athletes. Basketball players don&#8217;t pull out a calculator every time they take a shot. They rely on past experience to learn what force and direction works for different situations. To generate that type of response, the researchers designed a neural net, a computer system that mimics the brain.<\/p>\n<p>Like basketball players, neural nets require a lot of training before they can perform. But Chen said training the system by transmitting actual beams was very time-consuming. Instead, co-author Atsutse Kludze designed a simulator that allowed the net to train virtually for different obstacles and different environments.<\/p>\n<p>The math behind Airy beams is difficult, and Kludze, a doctoral student in Ghasempour&#8217;s lab, had to create a system that applied the underlying physics to almost any scenario.<\/p>\n<p>                                                                                                        <!-- TechX - News - In-article --><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Neural_net_calibrates_curves_with_perfect_precision\"><\/span>Neural net calibrates curves with perfect precision<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Throwing a lot of data at the neural net is not effective. Instead, the researchers use principles from physics to create and train the neural net. Once the system was trained, the neural net was able to adapt incredibly quickly.<\/p>\n<p>The researchers said they tested their scheme with experiments, which were focused on understanding the technology and developing ways to control the transmissions.<\/p>\n<p>&#8220;This work tackles a long-standing problem that has prevented the adoption of such high frequencies in dynamic wireless communications to date,&#8221; Ghasempour said.<\/p>\n<p>&#8220;With further advances, we envision transmitters that can intelligently navigate even the most complex environments, bringing ultra-fast, reliable wireless connectivity to applications that today seem out of reach\u2014from immersive virtual reality to fully autonomous transportation.&#8221;<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\tA Physics-Informed Airy Beam Learning Framework for Blockage Avoidance in sub-Terahertz Wireless Network, <i>Nature Communications<\/i> (2025). <a rel=\"nofollow\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s41467-025-62443-0\" target=\"_blank\">DOI: 10.1038\/s41467-025-62443-0<\/a><\/p>\n<\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Princeton University<br \/>\n                                                    \t\t\t\t\t\t\t\t\t\t\t\t\t<a rel=\"nofollow\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.princeton.edu\/main\/\" target=\"_blank\" rel=\"nofollow\"><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>\n                                                <strong>Citation<\/strong>:<br \/>\n                                                Engineers send a wireless curveball to deliver massive amounts of data (2025, August 18)<br \/>\n                                                retrieved 18 August 2025<br \/>\n                                                from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2025-08-wireless-curveball-massive-amounts.html\n                                            <\/p>\n<p>\n                                            This document is subject to copyright.
