Inquiry about 802.11 ac Compatibility

[EnriqueIV]

Hello Everyone

Good day, I am writing to inquire about the compatibility of the 802.11 ac standard with different frequency bands. I would like to know if 802.11ac is capable of operating on the 2.4 GHz frequency band, or if it is exclusively designed for the 5 GHz band.

This company its a global leader in developing and manufacturing Wi-Fi chips, staffed by the brightest mind. Any information you can provide regarding this matter would be greatly appreciated.

Thank You

Hi, EnriqueIV.

Thank you for posting in our Community.

Before we move forward with this matter, I would like to ask for further details:

• Are you currently using or planning to use 802.11ac on a dual-band router? This helps determine if you are considering both 2.4 GHz and 5 GHz for their devices.
• What types of devices are you planning to connect using 802.11ac? Understanding the types of devices helps gauge whether 2.4 GHz or 5 GHz will better suit to your needs.
• Is there a specific reason you’re focused on using 802.11ac on the 2.4 GHz band? This will clarify if you are facing a particular limitation or challenge with the 5 GHz band.

Have a nice day!

Best regards,

Hi, EnriqueIV.

To clarify, the 802.11ac standard, also known as Wi-Fi 5, is primarily designed to operate on the 5 GHz frequency band, offering faster speeds and more efficient performance compared to earlier standards like 802.11n (Wi-Fi 4), which typically operates on the 2.4 GHz band. However, many modern routers and devices that support 802.11ac are dual-band and also support the 2.4 GHz band, but in that case, they would fall back to the older 802.11n standard when operating at 2.4 GHz. The 802.11ac standard itself is not optimized for the 2.4 GHz band, and it will generally offer lower speeds and performance when used there.

To sum it up, 802.11ac is designed for 5 GHz, but devices may still support 2.4 GHz for backward compatibility using 802.11n.

Additionally, I have not heard back from you, I will close this inquiry now. If you need further assistance, please submit a new question as this thread will no longer be monitored. If you have any further questions, feel free to reach out.

Hello Von

Good day, first of all thank you for taking time to answer my pots. Let me give you a little context in this matter, I work in a testing laboratory in Mexico we test the technical disposition 008-15  that its likely the FCC 15.247 and 15.407 in the US. recently a client had a complain she mentioned that the device under test works in 802.11 ac in 2.4 GHz and we only tested in 5.8 GHz, after several days researching (including the post) and reviewing the equipment thoroughly as you mentioned in your response, we only see the behavior of 802.11 n  in 2.4 GHz. Finally with the evidence necessary mostly technical specifications and answers by the designer and maker of that device we went able to solved it. You response will help us to understand better why its used more 8021.11 ac in 5.8 GHz. and once again thank you for your help and very sorry for the late replay

Enrique.
