The difference between the frequencies 2.4 GHz, 5 GHz, 6 GHz, and 6E

The difference between the 2.4 GHz, 5 GHz, 6 GHz, and 6E (sometimes incorrectly referred to as 7 GHz) frequencies lies in the performance, range, and applications used by each frequency. These frequencies are commonly used in modern Wi-Fi networks, especially with the emergence of technologies such as Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7 .

Here is a clear comparison between each of them:

🔹 1. Frequency 2.4 GHz

  • ✅ Range : Longest range.
  • ❌ Speed : The slowest speed.
  • 📡 Interference : More susceptible to interference (because many devices use this range such as microwaves, Bluetooth, and remote controls).
  • ⚙️ Its uses : Suitable for simple-use devices such as the Internet of Things (IoT), old routers, cameras, etc.
  • 🧱 Wall Penetration : Best wall penetration.

🔹 2. 5 GHz frequency

  • ✅ Range : less than 2.4 GHz.
  • ✅ Speed : Higher than 2.4 GHz.
  • 📡 Interference : Less susceptible to interference.
  • ⚙️ Its uses : Suitable for transferring data at high speeds such as watching, gaming, and remote work.
  • 🧱 Wall Penetration : Less able to penetrate walls compared to 2.4 GHz.

🔹 3. Frequency 6 GHz

  • ✅ Range : Shorter than 5 GHz.
  • ✅ Speed : More than 5 GHz.
  • 📡 Interference : Less interference because it is a relatively new and unsaturated frequency.
  • ⚙️ Support technology : Only available on Wi-Fi 6E and Wi-Fi 7 .
  • 📶 Number of channels : Supports wider channels (up to 160 MHz), which increases speed.
  • 🧱 Wall penetration : Very weak.

🔹 4. 7 GHz frequency (actually: part of Wi-Fi 7 or 6 GHz + 6E)

  • ❗ There is no independent "7 GHz frequency" in the traditional sense.
  • ✅ Wi-Fi 7 uses 2.4 GHz, 5 GHz, and 6 GHz frequencies with significant improvements.
  • 🚀 Key Feature : Use of Multi-Link Operation (MLO) technology that allows the use of more than one band at the same time to increase speed and stability.
  • 📐 Channels : Supports channels up to 320 MHz.
  • 💯 Theoretical speed : Can exceed 40 Gbps (theoretical) in some settings.


📊 Summary of the differences:


🎯 When do you choose each frequency?

  • 2.4 GHz ➤ If you need wide and distant coverage, and you don't have a high need for speed.
  • 5 GHz ➤ If you are close to the router and want good speed for activities like downloading, gaming, and streaming.
  • 6 GHz (Wi-Fi 6E or Wi-Fi 7) ➤ If you want the best speed and lowest latency, and you have a modern router.
  • Wi-Fi 7 (with 6GHz+) ➤ If you are an advanced user or need amazing speeds without interruption.
