Wi-Fi 7 has emerged as a technical response to this limitation, with two fundamental advances: <strong>RU (Resource Unit)<\/strong> and <strong>MRU (Multi-Resource Unit)<\/strong>.  <\/p>\n\n<p>These new mechanisms operate as true digital traffic engineers, optimizing spectrum allocation, reducing latency and ensuring greater spectral efficiency.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/made4it.com.br\/wp-content\/uploads\/2025\/05\/Antes-e-depois-com-RU-e-MRU-V2-1024x629.png\" alt=\"\" class=\"wp-image-15423\"\/><\/figure>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/made4it.com.br\/wp-content\/uploads\/2025\/05\/Frame-2.png\" alt=\"\" class=\"wp-image-15429\"\/><\/figure>\n\n<h2 class=\"wp-block-heading\"><strong>OFDMA and RU: Dividing the Highway with Intelligence<\/strong><\/h2>\n\n<p>Since Wi-Fi 4 (802.11n), orthogonal frequency division multiplexing (OFDM) has been used to transmit data on multiple subcarriers simultaneously. With Wi-Fi 6, <strong>OFDMA<\/strong> brought the idea of <strong>RU<\/strong> &#8211; smaller divisions of the subcarrier &#8211; which allow multiple devices to transmit data simultaneously within the same channel, allocating different RU sizes as needed. <\/p>\n\n<p>However, there was a limitation: each device could only use <strong>one RU per transmission<\/strong>. This led to latency in heavier applications, even with idle spectrum. <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>MRU: The Intelligent Combination of Resources<\/strong><\/h2>\n\n<p>Wi-Fi 7 breaks this limitation with the <strong>MRU<\/strong> concept. <strong>Multiple contiguous or non-contiguous RUs<\/strong> can now be <strong>grouped together<\/strong> to form a larger logical block. This allows devices with large volumes of data to transmit with <strong>minimal latency and higher throughput<\/strong>, using the spectrum much more efficiently.  <\/p>\n\n<p>This flexibility is crucial in scenarios such as industries, hospitals and smart cities.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Puncturing: Avoiding Interference Without Sacrificing the Channel<\/strong><\/h2>\n\n<p>Another advance in Wi-Fi 7 is <strong>puncturing<\/strong>. Unlike Wi-Fi 6, where interfered sub-carriers were rendered unusable, Wi-Fi 7 makes it possible to <strong>isolate<\/strong> these compromised bands and keep the others operating normally. This dramatically increases <strong>resilience to interference<\/strong>.  <\/p>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/made4it.com.br\/wp-content\/uploads\/2025\/05\/Frame-3.png\" alt=\"\" class=\"wp-image-15432\"\/><\/figure>\n\n<h2 class=\"wp-block-heading\"><strong>What MRU Improves in Practice<\/strong><\/h2>\n\n<ul class=\"wp-block-list\">\n<li><strong>Latency reduction<\/strong>: Immediate aggregation of available RUs, reducing the wait for high-volume transmissions.<\/li>\n\n\n\n<li><strong>Spectral efficiency<\/strong>: idle RUs are dynamically reused according to network demand.<\/li>\n\n\n\n<li><strong>Interference Tolerance<\/strong>: Redistribution of traffic between active sub-carriers without full channel loss.<\/li>\n<\/ul>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Specification<\/strong><\/td><td><strong>Wi-Fi 6<\/strong><\/td><td><strong>Wi-Fi 7<\/strong><\/td><\/tr><tr><td>Channel width<\/td><td>Up to 160 MHz<\/td><td>Up to 320MHz<\/td><\/tr><tr><td>Modulation<\/td><td>1024-QAM<\/td><td>4096-QAM<\/td><\/tr><tr><td>Maximum speed<\/td><td>9.6 Gbps<\/td><td>46 Gbps<\/td><\/tr><tr><td>MRU + Puncturing<\/td><td>Not available<\/td><td>Implemented<\/td><\/tr><tr><td>Efficiency with MRU<\/td><td>Limited<\/td><td>Up to 40% gain<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Source: Broadcom, Intel, Qualcomm<\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\"><strong>Advanced applications with MRU<\/strong><\/h2>\n\n<ul class=\"wp-block-list\">\n<li><strong>Smart Factories<\/strong>: Low latency communication between sensors, actuators and computer vision.<\/li>\n\n\n\n<li><strong>RA\/RV<\/strong>: Image and motion synchronization with a latency of less than 10ms.<\/li>\n\n\n\n<li><strong>Smart Cities and V2X<\/strong>: Traffic lights, vehicles and connected infrastructure operating in real time.<\/li>\n<\/ul>\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/made4it.com.br\/wp-content\/uploads\/2025\/05\/Aplicacoes-wifi-7-1024x595.png\" alt=\"\" class=\"wp-image-15435\"\/><\/figure>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/made4it.com.br\/wp-content\/uploads\/2025\/05\/Frame-4.png\" alt=\"\" class=\"wp-image-15438\"\/><\/figure>\n\n<h2 class=\"wp-block-heading\"><strong>Efficiency, Flexibility and Intelligence<\/strong><\/h2>\n\n<p>RU and MRU don&#8217;t just increase speed &#8211; they <strong>redefine wireless communication architecture<\/strong>.
