That\u2019s where OFDMA, or\u00a0Orthogonal Frequency-Division Multiple Access, comes in. So what does it do exactly, and do you need it?<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"What_Does_OFDMA_do\"><\/span>What Does OFDMA do?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The way that Wi-Fi used to work traditionally is that each user would compete for the single connection or channel that was available. While this wasn\u2019t necessarily a big issue back in the days when you would only have one or two devices connected, nowadays, nearly everything requires some connection, and that causes congestion. As such, the old way of doing things doesn\u2019t cut it anymore.<\/p>\n<p>OFDMA is an attempt to fix that issue, and you\u2019ll probably be surprised to find out that it\u2019s even used in 5G telecoms and comes standard with Wi-Fi 6.<\/p>\n<p>Essentially, how it works is that it takes a channel and subdivides it into smaller channels, which are then distributed to the different devices that need to be connected. Interestingly, OFDMA isn\u2019t necessarily there to increase the <em>capacity<\/em> of most connections but rather to make them more efficient and decrease latency. That\u2019s important in a place with a dozen different devices competing for a single channel and is great for low-bandwidth usages, such as smart home devices.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Whats_the_Difference_Between_OFDMA_and_MU-MIMO\"><\/span>What\u2019s the Difference Between OFDMA and MU-MIMO?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Now, you may have heard of MU-MIMO, or Multiple User, Multiple-Input, Multiple-Output, and feel a bit perplexed. Doesn\u2019t it do the same thing, allowing more than one device to connect to a router and decrease congestion? So why do we need two standards that do the same thing?<\/p>\n<p>Simply put, OFDMA and MU-MIMO are complementary technologies that work together. MU-MIMO does something similar, but rather than subdividing a single channel into smaller ones, MU-MIMO <em>creates<\/em> different channels, achieved by having more antennas.<\/p>\n<p>To use a simple analogy, OFDMA is like sending several boats down a single river, and MU-MIMO is like creating different rivers, each with its own boat.<\/p>\n<p>Both allow you to reach several places simultaneously, but OFDMA is better for smaller boats that won\u2019t cause congestion, and MU-MIMO is better for larger boats that can take up a lot of space in the river. In that sense, MU-MIMO is great for increasing capacity and serving high-bandwidth <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lications, such as streaming films, <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/watch-movies-tv-seriess\/\" data-internallinksmanager029f6b8e52c=\"8\" title=\"Watch Movies &amp; TV Series\" target=\"_blank\" rel=\"noopener\">movies<\/a>, <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/game\/\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Game\" target=\"_blank\" rel=\"noopener\">game<\/a>s, etc.<\/p>\n<p>That\u2019s why these are complementary technologies. OFDMA is made for the multitude of IoT devices that don\u2019t require a lot of data (smaller boats), and MU-MIMO is made for the big stuff like Desktops and TVs that do require a lot of data (bigger boats).<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Do_I_Need_OFDMA\"><\/span>Do I Need OFDMA?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you have a lot of devices that take up small amounts of data, such as smart switches, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.reviewgeek.com\/100281\/the-best-smart-lights\/\">smart lights<\/a>, or smart appliances, then yes, OFDMA is very handy to have.<\/p>\n<p>Luckily, as we mentioned earlier, Wi-Fi 6 already comes with OFDMA as standard, so if you have a router that supports Wi-Fi 6, then you already have it! On the other hand, if you\u2019re looking to upgrade your router to get access to OFDMA, you might want to buy a router with Wi-Fi 6E, which gives access to the 6Ghz band and helps decrease congestion overall.<\/p>\n<p>That being said, if you don\u2019t have quick or budget-friendly access to Wi-Fi 6E, Wi-Fi 6 is still excellent, so don\u2019t worry about missing out on anything.<\/p>\n<\/div>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
