Lorawan in a high-density 802.11 environment

Curious if anyone has an input on this-

I work for a large company with several industrial manufacturing locations with high density 2.4/5GHz 802.11 deployment. It’s a complex RF environment already of course- huge metal structures, powerful EM fields, etc. Our APs are at close to max permissible density is some parts of the plants.

One of the locations wants to do a POC with Lorawan-based environmental sensors. They would be talking on sub GHz frequencies so I understand they would not directly interfere with the existing wifi signals.

I don’t have a lot of experience with mixing RF technologies like this. Even though the Lorawan equipment would be operating in the low 900s MHz my question is if just having another RF-talker in that space could impact the standard wifi signals due to the overall RF energy in the environment. I realize that’s a poor way to ask the question but can’t think of a better phrasing at the moment. Hopefully you get what I mean…
