Overview
WiFi 6 is the latest mainstream WiFi standard that makes wireless networks faster, more reliable, and more efficient in busy environments. It works on both 2.4 GHz and 5 GHz bands and is backwards compatible with older devices. WiFi 6E is a related version that also operates in the 6 GHz band, where permitted.
Core Improvements
Instead of focusing only on peak speeds, WiFi 6 is designed to handle many devices at once. It introduces several key features:
-
OFDMA: Splits a channel into smaller parts so multiple devices can send or receive data at the same time. This reduces waiting and improves performance.
-
MUMIMO (uplink and downlink): Access points can now send and receive data from several devices simultaneously, not just one after another.
-
1024QAM: A more efficient way of encoding data, giving faster speeds for devices with strong connections.
-
BSS Colouring: Helps devices ignore unnecessary signals from nearby networks, cutting interference.
-
Target Wake Time (TWT): Lets devices schedule when to connect, saving battery life for mobiles and IoT devices.
Everyday Benefits
With WiFi 6, you get smoother video calls, lower lag in online apps, more consistent speeds for each device, and better performance even when dozens of devices are connected at once. Large offices, schools, and homes with many smart devices benefit the most.
Deployment Tips
To use WiFi 6, upgrade access points to models that support it and plan your channels based on local spectrum rules. Turn on features like OFDMA and MUMIMO, and check if WiFi 6E is available in your region for added capacity. You don’t need to replace all your devices immediately; upgrading the access layer brings immediate gains.
