Can too many frequencies or just wifi signals cause problems in a closed space? Why or why not?

Reason why this came to me. I recently was using a digital audio board in a room with 300 people/cellphones, police/fire/emt with radios and multiple wifi networks. My ipad refused to connect to the audio board. So this got me thinking if it was possible to have too much wireless clutter in the air. Added bonus if anyone can explain how to avoid this problem but understanding if and how it happens is most important. Thanks!

There are a number of things that could be happening here. The first is, yes, wireless interference. Wifi networks operate in certain distinct sets of frequencies, primarily in the 2.4 GHz range, the 5 GHz range, and more recently, the 6 GHz range. Within these ranges are a set number of “channels”, or blocks of frequency in which different networks can operate without interfering with each other. But if there are multiple networks operating on the same channel (or close to the same channel), which is particularly problematic on older networks that used only 2.4 GHz which only have a few channels that don’t overlap with each other, then yes, there can be interference. The 2.4 GHz problem is exacerbated by the fact that there are a ton of wireless devices that use that frequency range, and even something like a microwave oven can cause interference at that frequency. Thankfully, there are very few wifi devices these days that operate solely on 2.4 GHz.

Another possible problem is that you had too many devices connected to your particular wifi network, and either the wireless hotspot or the router was overwhelmed by all of the traffic trying to go through it, and you were dropping your connection as a result.

A third possible problem is just that there was just a configuration issue within the network, or some other hardware fault with the mixer or your iPad. There are some digital mixers, like the Behringer XR18, which have built-in wifi which is notoriously bad, you should always use an external wireless router with those.

In your particular scenario, the digital mixer should be on a dedicated, secured wireless network that nothing else (or very few other things) connect to, making sure that the wireless channel that it’s set to doesn’t overlap with any other permanent wireless networks in that area.
