What is the difference between wifi4 and wifi6

Wi-Fi 4 (IEEE 802.11n) and Wi-Fi 6 (IEEE 802.11ax) are two different Wi-Fi standards with significant differences .

1. Data transmission speed: Wi-Fi 6 can achieve a peak data transmission rate of up to 9.6 Gbps, while Wi-Fi 4 can only achieve a maximum data transmission rate of 600 Mbps. This means that Wi-Fi 6 has faster data transfer speeds relative to Wi-Fi 4 and can handle high-load tasks faster.

2. Network capacity: Because Wi-Fi 6 uses OFDMA technology, which can divide the wireless channel into multiple sub-channels and support multiple users at the same time, Wi-Fi 6 can be more efficient Optimizing the use of network bandwidth allows more devices to be connected to the same wireless router, thereby increasing network capacity while also reducing congestion and latency.

3. Network security: Wi-Fi 6 introduces the WPA3 protocol, which can provide more powerful encryption and authentication functions to protect user privacy and data security. In contrast, Wi-Fi 4 uses the older WPA2 protocol, which has relatively weak security.

In general, Wi-Fi 6 has faster speeds, more stable connections, higher network capacity, and more advanced security than Wi-Fi 4 , which makes Wi-Fi 6 an important trend in future network development.
