2. Bandwidth and number of channels:

• WiFi 6 (802.11ax): In the 5 GHz band, provides more bandwidth and more channels to reduce interference and congestion.
• WiFi 6E (802.11ax): By adding a new 6 GHz frequency band, it provides wider bandwidth and more channels, further reducing interference and improving network performance.

3. Higher speed and capacity:

• WiFi 6 (802.11ax): Provides higher speed and capacity, supports more devices to connect simultaneously, and faster data transfer speeds.
• WiFi 6E (802.11ax): In the 6 GHz band, it provides higher speeds and greater capacity, further improving network performance and reducing congestion.

4. Enhanced coverage and penetration:

• WiFi 6 (802.11ax): Provides some level of enhancement, but is limited by the 5 GHz band.
• WiFi 6E (802.11ax): The 6 GHz band has better penetration and lower interference, providing wider coverage and more stable connections.

5. Lower interference and congestion:

• WiFi 6 (802.11ax): Although it provides more channels in the 5 GHz band, there is still the possibility of interference from other WiFi networks and wireless devices.
• WiFi 6E (802.11ax): The 6 GHz band is relatively new and typically has fewer devices and networks, thus reducing interference and congestion and providing a more stable connection.

6. Supported devices:

• WiFi 6 (802.11ax): Requires a device that supports the 802.11ax standard.
• WiFi 6E (802.11ax): Requires a device that supports the 802.11ax standard and has a 6 GHz frequency band.

 

 

 

 

WiFi 7 (802.11be):

Operates in the 2.4 GHz, 5 GHz and 6 GHz frequency bands.

 

1. speed:

• WiFi 7 is expected to deliver speeds of up to 30 Gbps, several times faster than WiFi 6.
• Faster speeds mean faster downloads, uploads and streaming experiences, especially for large file transfers and HD videos.

2. capacity:

• WiFi 7 further increases the capacity of the network and can connect more devices simultaneously, possibly thousands.
• It can better cope with the needs of future smart homes and workplaces and maintain network stability and efficiency.

3. Delay:

• WiFi 7 will further reduce latency, expected to be below the millisecond level, achieving almost imperceptible instant response.
• This will be an important improvement for applications that require high real-time performance, such as virtual reality, telemedicine and industrial automation.

4. safety:

• WiFi 7 introduces stronger security features, including stronger encryption and authentication standards.
• Improves network security and reduces the risk of hacker attacks.

 

 

Comparison between two technologies

• WiFi 7 is more advanced and powerful than WiFi 6 in terms of speed, capacity and latency.
• WiFi 7 is more suitable for future application scenarios that have higher requirements for network performance and capacity, such as 5G communications, big data transmission and smart homes.
• WiFi 6 is still a good choice, especially suitable for current needs. It provides sufficient speed and performance at a relatively more reasonable price.
• For users who require higher speeds, more capacity, and lower latency, WiFi 7 will be the better choice, but may come at a higher price.

 

 Summary Points

WiFi 6 (802.11ax) is a revolutionary technology operating in the 2.4 GHz and 5 GHz frequency bands, providing speeds of up to 9.6 Gbps. It can connect more devices at the same time, theoretically supporting hundreds of devices, reducing network congestion and delay, and ensuring network stability.
