In 2018, the Wi-Fi Alliance introduced a more user-friendly way to identify Wi-Fi standards. Instead of technical terms like 802.11ax, the naming system became numerical.
Wi-Fi 6 represents the latest advancement in wireless technology, succeeding Wi-Fi 5 (802.11ac) and Wi-Fi 4 (802.11n). Along with a new name, Wi-Fi 6 brought transformative features to wireless networking.
Managing Multiple Devices with Wi-Fi 6

Wi-Fi 6’s standout improvement is its ability to handle crowded networks effectively. Using MU-MIMO technology, it can communicate with multiple devices simultaneously.
This upgrade is similar to adding extra gas pumps at a busy station—more users can access the network simultaneously without delays.
Key technologies like OFDMA and transmit beamforming further optimize network performance.
These enhancements ensure seamless connectivity, even in homes packed with devices like phones, laptops, and smart TVs.
Notable Advantages:
- Better performance with many devices connected.
- Improved reliability in crowded places, such as stadiums or shopping centers.
- Enhanced security with WPA3 for safer connections.
Tailored for Smart Homes and IoT
While Wi-Fi 5 worked well for basic networking needs, Wi-Fi 6 is designed for modern smart homes and IoT (Internet of Things) devices.
Features like 1024QAM boost data transfer speeds by 25%, while Target Wake Time (TWT) helps save energy by managing device communication more efficiently.
These features reduce congestion and ensure smoother operations for gadgets like smart cameras and speakers, making Wi-Fi 6 a perfect match for connected households.
How to Ensure Compatibility with Wi-Fi 6?
To fully benefit from Wi-Fi 6, you need a compatible router and device. Using an older router or device will limit the performance enhancements.
Initially, Wi-Fi 6 routers were costly, ranging between $340 and $500. Over time, prices have dropped, and flagship devices like the Samsung Galaxy S10 series started incorporating Wi-Fi 6.
Many devices now display a small “6” next to the Wi-Fi icon to indicate compatibility.
Is It Time to Upgrade?

Wi-Fi 6 offers theoretical speeds of up to 9.6Gbps, which may exceed the speed of many internet plans. An upgrade might not be urgent if you have a slower connection or fewer devices. However, households with outdated routers or many connected devices can see noticeable improvements.
Wi-Fi 6 vs. Ethernet
Although Wi-Fi 6 delivers impressive speeds, Ethernet cables provide better reliability and consistency.
For example, a Category 6 Ethernet cable can maintain gigabit speeds over long distances with minimal interference. Wi-Fi is more convenient, but wired connections remain superior for tasks requiring minimal latency.
Has Wi-Fi 6 Become Commonplace?

Wi-Fi 6 is now standard in many devices, including laptops and smartphones. However, budget smart home devices and ISP-provided routers often stick to older Wi-Fi standards due to cost constraints.
To check your router’s compatibility, look for the label “802.11ax” or a Wi-Fi symbol with “6.”
Exploring Wi-Fi 6E and What’s Next
Wi-Fi 6E expands Wi-Fi 6 capabilities by adding the 6GHz band, providing four times the capacity of traditional 2.4GHz and 5GHz bands.
This is especially helpful for crowded networks with numerous devices. However, a Wi-Fi 6E-compatible router is necessary to access this feature.
Devices like the Samsung Galaxy S21 Ultra were among the first to support Wi-Fi 6E. Looking ahead, Wi-Fi 7 promises even faster speeds and enhanced connectivity, but at a higher cost.
