Wi-Fi 6 (802.11ax) is becoming the focus point of wireless networks everywhere as we slowly start to upgrade our existing hardware and software to utilise the added features for ours and users benefits. This blog post is an overview of the features that have been brought in with Wi-Fi 6 to reacquaint myself before I get too stuck into Christmas.   Wi-Fi 6 MU-MIMO  The previous two iterations of the wireless standard have allowed for the use of more than one concurrent transmission from a single transmitter known as a spatial stream. This is most notably with 11n the first standard that allowed four max and brought in the use of (Multiple Input Multiple Out) to utilise this increase in transmit potential. This in theory allowed up to four signals to be sent at the same time from the same device, four times as many bits, increasing overall throughput.  8011.ac ramped that number up to eight max spatial streams that allowed eight times the bits (simple maths isn't it)...

  The usage of 5Ghz frequency and the inevitable progression of the wireless standard has led to many benefits over the years. The most notable advances being the latest three standards; 802.11n known as the High-Throughput, leading to 802.11ac known as the Very-High-Throughput and 802.11ax (Wi-Fi 6) known as High-Efficiency. With these new standards a huge list of benefits comes not only to personal usage at home but also corporate space. Most notably one of the main benefits is data rates (as per the first two standard’s names). 802.11n (High-Throughput) built upon previous released standards, 802.11a for 5Ghz and 802.11g for 2.4GHz which achieved throughputs around 50Mbps. 11n bumped the data rate up all the way to a max 600Mbps which is a huge increase giving rise to its name. From here, any future standards such as 802.11ac or 11ax have always added to the ever-growing max data rates available, 11ac being nearly 7Gbps and 11ax on the push for the 10Gbps barrier. But with...
