What is Wi-Fi 6 and How Is It Different from Wi-Fi 5?

Wi-Fi 6 is the 6th generation Wi-Fi technology.
It is smoother, faster, stronger, and can handle many more devices compared to Wi-Fi 5.

✔ Key Improvements:

  • Up to 2× faster than Wi-Fi 5
  • Better range and stronger signal stability
  • Better performance when many devices are connected


Wi-Fi 6 Speed Classes

Common types of Wi-Fi 6:

  • AX1800
  • AX3000
  • AX5400

(Each type has different speed on 2.4GHz and 5GHz bands.)

AX1800 (Wi-Fi 6)

Total Speed ≈ 1800 Mbps

Band

Speed

2.4GHz (2G)

574 Mbps

5GHz (5G)

1201 Mbps

✔ 574 + 1201 = 1775 Mbps (≈1800)


 AX3000 (Wi-Fi 6)

Total Speed ≈ 3000 Mbps

Band

Speed

2.4GHz (2G)

574 Mbps

5GHz (5G)

2402 Mbps

✔ 574 + 2402 = 2976 Mbps (≈3000)


 AX5400 (Wi-Fi 6)

Total Speed ≈ 5400 Mbps

Band

Speed

2.4GHz (2G)

574 Mbps

5GHz (5G)

4804 Mbps

✔ 574 + 4804 = 5378 Mbps (≈5400)



Advanced Technologies in Wi-Fi 6

Wi-Fi 6 includes several modern features that Wi-Fi 5 does not have:

  1. OFDMA – Handles multiple devices at the same time without slowing down.
  2. MU-MIMO (Improved) – Better upload/download for multiple users.
  3. BSS Coloring – Reduces Wi-Fi interference from neighbors.
  4. TWT (Target Wake Time) – Saves battery for devices.
  5. WPA3 Security – Latest and strongest Wi-Fi security standard.


Why Nepali Customers Need Wi-Fi 6

In Nepal, most homes have 5 to 10+ devices connected at the same time:

  • Phones
  • Laptops
  • Smart TV
  • CCTV
  • Smart gadgets
  • ONU from ISP

Wi-Fi 5 becomes slow when many devices use the network.
Also, interference from nearby houses reduces Wi-Fi range and speed.
