Wi-Fi 6: High-Efficiency WLAN with IEEE 802.11ax [UPDATED]

The 802.11ax brings important features, focusing on network capacity, latency and range. High data rates are still in the picture, but rather in the background. Introducing OFDMA and using MU-MIMO allows AP to schedule data for multiple users simultaneously. This way, latency can be greatly decreased. With the new colors of the channels, frequencies can be spatially reused.

Wi-Fi 6: Q&A

What is Wi-Fi 6 (IEEE802.11ax)? How does it compare to Wi-Fi 5 (IEEE802.11ac)? Will older phones connect to Wi-Fi 6? The post combines the most frequently asked questions about Wi-Fi 6.

Wi-Fi issues: site-surveys and troubleshooting

Recently, we’ve been doing numerous site surveys and verification of Wi-Fi deployments in offices with more than 50APs per office in a managed setup (meaning that the APs are under the supervision of a wireless controller). In this post, I’d like to sketch an overview of the encountered issues and improvement suggestions.

Why Wi-Fi 6 (IEEE802.11ax) will be different than previous Wi-Fis?

The AP schedules the transmission according to the actual needs, and nobody wastes time on waiting and on collision. So, we end-up having the system that: is more robust towards low latency services; is more spectrally efficient; allows for actually use some QoS profiles; and coordinates the use of spectrum.

Wi-Fi Generations – new naming convention for WiFi

Wi-Fi Generations affect not only new releases, but also refer to the past amendments. Currently Wi-Fi Alliance has defined 6 generations. Each step is significant improvement in network performance and security. No more minor version changes that can cause only confusion.

Wi-Fi Radio Configuration & Measurements

This post discusses selected practical aspects of Wi-Fi systems including: explanation of some parameters and factors that the network performance is impacted by; showing how to configure some of the parameters them using CISCO Wireless LAN Controller; presenting simulated scenarios to show some examples of radio measurements.
