The Road to WiFi 6E Part 2: Increased Link Rate
This blog post is the second in a series of articles we’ll be presenting over the course of 2022 about WiFi 6 (and WiFi 6E) – the current and future top-of-the-line WiFi standards championed by the WiFi Alliance. We’ll be discussing the history of the evolving standard of WiFi, new features introduced in WiFi 6 and 6E, applications beyond the commonly known consumer use cases, and much more. Additionally, we’ll be releasing a companion series of video interviews with Laird Connectivity experts, which you can find here.
A Tidal Wave of Data – How WiFi 6 Serves Today’s Applications
In our introductory blog post on WiFi 6 and 6E, we covered the history of WiFi and how it’s been used to serve an ever-evolving list of applications. WiFi became the default standard in wireless networking by constantly evolving to meet users’ needs. And along the way to WiFi 6 and 6E, that has translated to a 480x increase in deliverable link rates for WiFi client devices.
Today’s wireless ecosystem has demands that would have been thought impossible in 1999; 4K video streaming, multitudes of lower-resolution security-type video monitoring, telepresence tools and remote surgical devices, and other applications have extreme demands. Lots of data throughput, low latency requirements, and more are manifest in today’s emerging wireless devices. WiFi 6 and 6E are ready to deliver on those requirements.
That’s the “what” of the WiFi standard’s evolution. In this post, we’re looking at the “how,” specifically the sub-features, modulation schemes, channel configurations, stream topologies, and more that enable WiFi 6 and 6E to deliver 9.6 Gbps maximum data rate across 8 spatial streams (1.2 Gbps per stream), a truly impressive upgrade over the 3.5 Gbps total made available in Wi Fi 5 and how they relate to your applications and how you can use them, to create industry leading solutions.
