Wi-Fi 5 vs. Wi-Fi 6: 10 Key Differences - Which One is Better?

Wireless connections all over the world are constantly evolving, and each new generation comes with improvements in speed, reliability, and efficiency. Wi-Fi 5 (802.11ac) has been a trusted source of connection for years; the entry of Wi-Fi 6 (802.11ax) marked a major performance improvement, especially when the devices connected are in a large number. 

This blog is the complete guide to help you make the right choice for yourself by understanding the 10 key differences between Wi-Fi 5 vs Wi-Fi 6. 

Wi-Fi 5 vs. Wi-Fi 6: What’s The Difference? 

Wireless connection technology has become an important part of our lives, from working and gaming online to connecting devices just for fun. The technology power for the network needs to evolve when the connected devices grow in number, and we rely on it a little more than before. Let’s find out the hype of Wi-Fi 5 vs Wi-Fi 6.

Wi-Fi 6 (802.11ax) came just when our lives needed something more than Wi-Fi 5 (802.11ac). Wi-Fi 5 has been a great support for everyone in its time, but Wi-Fi 6 made it all even better with its performance, efficiency, and capacity. 

1. Generation and Naming

• Wi-Fi 5 (802.11ac) used to target faster speeds over the 5 GHz band, was introduced in 2014. 
• Wi-Fi 6 (802.11ax) arrived in 2019 and brought the next generation of wireless networking with more efficient data delivery.

The numbering system (Wi-Fi 4, 5, 6) was introduced to make it easy for consumers to understand the Wi-Fi system and the competition between Wi-Fi 5 vs Wi-Fi 6. 

2. Speed and Maximum Throughput

• Wi-Fi 5 offers numerical speeds of up to 3.5 Gbps.
• Wi-Fi 6 can go up to 9.6 Gbps, almost triple the speed of Wi-Fi 5, making the Wi-Fi 6 vs Wi-Fi 5, even more competitive. 

But Wi-Fi 6 is not only about speed, it’s about better speed distribution throughout multiple connected devices, especially when they’re connected at one time. 

3. Frequency Bands

• Wi-Fi 5 operates only on the 5 GHz band, which brings high speed but in a limited range.
• Wi-Fi 6 works on 2.4 GHz and 5 GHz, with balanced range and performance and while being more adaptable to various environments.

This dual-band operation means Wi-Fi 6 performs better in areas where 5 GHz finds it difficult to reach, making the Wi-Fi 5 vs Wi-Fi 6 range game even more intense. 

4. Network Efficiency (OFDMA and MU-MIMO)

• Wi-Fi 5 introduced MU-MIMO while allowing routers to connect with multiple devices smoothly, but only in a limited range. 
• Wi-Fi 6 boosts this with MU-MIMO and adds OFDMA, a technology that breaks channels into smaller sub-channels to serve multiple devices more efficiently at once.

To have a better understanding of Wi-Fi- 5 vs Wi-Fi 6, think of Wi-Fi 5 as a single-lane road, and Wi-Fi 6 as a multi-lane highway, each lane delivering data to different devices and users simultaneously.

5. Battery Life Improvements (TWT)

• This Wi-Fi 6 vs Wi-Fi 5 standard does not support any features for saving battery or reducing battery drain worn on the device. 
• Wi-Fi 6 has introduced a new feature known as Target Wake Time (TWT), allowing connected devices to go into a deliberate night or sleep mode in time with their wake- up call, making sure that, when needed, they will still consume less energy. 

6. Performance in Crowded Environments

• Wi-Fi 5 struggles with many connected devices, which leads to slowdowns in dense environments such as apartments, offices, or smart homes.
• Wi-Fi 6 is designed to handle four times the number of devices that Wi-Fi 5 can, which is useful when dealing with many users and devices.

7. Security Enhancements

• Wi-Fi 5 utilizes WPA2 encryption, which is still secure, but starting to show its age against modern cyber threats.
• Wi-Fi 6 utilizes WPA3 encryption, which means stronger encryption, and better password protections, and unique encryption of individual data, especially in public and enterprise settings.

8. Latency and Responsiveness

• Wi-Fi 5 often experiences higher latency in multi-device scenarios, affecting things like gaming and video calls.
• Wi-Fi 6 significantly reduces latency, enabling smoother real-time experiences for applications like:

1. Cloud gaming
2. 4K/8K video streaming
3. AR/VR environments
4. Remote collaboration

9. Backward Compatibility

• Wi-Fi 5 is backward compatible with prior generations of Wi-Fi technology, but its performance will depend on the device.
• Wi-Fi 6 is backwards compatible with Wi-Fi 5 and prior technologies, so existing devices will still connect; however, they will not be able to take advantage of Wi-Fi 6's full capabilities unless they connect to Wi-Fi 6 enabled devices.

10. Key Takeaways: Wi-Fi 5 vs. Wi-Fi 6

Wi-Fi 5 vs. Wi-Fi 6 vs. Wi-Fi 6E: The Basic Understanding 

When comparing the two in terms of Wi-Fi version, Wi-Fi 5 vs Wi-Fi 6, there is just more to consider than speed-most especially, Wi-Fi 6 has an entirely improved capacity, security, and operation in environments where many devices are used. In view of the above, most people who are interested in Wi-Fi 6 vs Wi-Fi 5 comparison also discuss network congestion as well as battery life improvement-in which terms, Wi-Fi 6 indeed prevails. 

The Wi-Fi 5 vs Wi-Fi 6 range testifies to the fact that, irrespective of distances being short or long, Wi-Fi 6 holds up better thanks to its dual-band configuration: both 2.4 GHz and 5 GHz. However, if you compare Wi-Fi 5, Wi-Fi 6, and Wi-Fi 6E, while Wi-Fi 6 is just an upgrade to 5, 6E makes a real difference by including a new access option to the extremely high speeds of 6 GHz, interference-free-the perfect solution for homes and businesses with an eye into the future. 

For any of those hoping to choose between wi-fi 5 vs wi-fi 6 at home or upgrade some appliances in the future, learning these key differences will be most useful in making the right choice.
