What are the different types of WiFi Technology?

Over the past few years, Wi-Fi standards have been simplified using numbers. Similar to mobile networks like 3G, 4G, and 5G. Each new version (Wi-Fi 4, 5, 6, 6E, and 7) generally means faster speeds, better security, and improved reliability for businesses.

Wi-Fi technology has evolved significantly, and the industry now uses simple numbering to make it easier to understand:

Wi-Fi Wireless Technologies
Wi-Fi Standard	Year	Freq. Bands	Max Speeds	New Feature
Wi-Fi 4 (802.11n)	2009	2.4 GHz 5 GHz	600 Mbps (0.6 Gbps)	Improved range and performance
Wi-Fi 5 (802.11ac)	2014	5 GHz	3,500 Mbps (3.5 Gbps)	Better efficiency for multiple users
Wi-Fi 6 (802.11ax)	2019	2.4 GHz 5 GHz	9,600 Mbps (9.6 Gbps)	Optimised for IoT and dense environments
Wi-Fi 6E (802.11ax-2021)	2021	2.4 GHz 5 GHz 6 GHz	9,600 Mbps (9.6 Gbps)	Reduced congestion and higher capacity
Wi-Fi 7 (802.11be)	2024	2.4 GHz 5 GHz 6 GHz	46,000 Mbps (46 Gbps)	Ultra-low latency and massive speed boost
Wi-Fi 8 (802.11bn)	TBA	2.4 GHz 5 GHz 6 GHz	TBA	Improve the reliability rather than increase speeds

Each upgrade improves speed, security, and reliability, making it essential for businesses to review their networks regularly. If your business hasn’t reviewed or replaced its Wi‑Fi in the last five years, it’s likely you’re experiencing unknown issues or random glitches.
