5G cellular network's interferance with WiFi

[Muhammed Adnan]

Hello Experts,

Its understood that the telecom licensed frequency is completely different from the unlicensed frequency spectrum the Wi-Fi uses.

However I find it difficult to find what specific frequency bands the 5G standard will be ratified for usage.

Will there be any scenario wherein their would be a probability of 5G cellular network impacting Wi-Fi, more specifically with regards to interference?

I do not think 5G will use same frequency used in WiFi, so there won't be any interference as such from 5G to WiFi.

Note that WiFi is used heavily for "indoor" deployments where as "5G" is intend to used for outdoor deployments.

Here is what I found from internet.

As Rasika wrote, they shouldn't overlap.
One important detail, if you are going to place a 4G or 5G antenna besides an AP, have at least 1 meter distance between them. If there is a wall between the two, then the distance can be a bit closer. Even if they use different frequencies, the electro magnetic field has a negative impact on the AP and probably mobile antenna.

Thanks Rasika, Patoberli for your responses.

Hi Patoberli

When it comes to electro magnetic field, should we be cautious about other elements that goes in the ceiling along side the Wireless access Points, including but not limited to cameras, lightings, speakers....
Could you please include more insight on this caution?

This is hard to say and would require specific measurements per device.

But in general, the better a device is insulated, the less issue it is. Sadly you can't see this without measuring it.

So in general, if it's a wireless sending device, keep some distance, if it's not operating wireless, you can close the distance but should still keep at least 50cm (in general). Of course it will also work if you have less distance, but maybe not as good.
