Could Wireless Be Better or Worse Than Wired Ethernet?

[The Computer Audiophile]

Hi Guys, I almost always use wired Ethernet because it just works every time. However, I've always wondered what the possible and/or realized issues are with using wireless, mainly, is RF an issue with sensitive audio components?

 

Question: Has anyone seen tests of audio equipment sensitivity to WiFi and any effects on the output of the audio devices?

Yeah, bandwidth isn't an issue at all. 

 

I'm thinking that if people use an access point behind their audio systems, where all the cables are, this could be an issue. I know this is also a popular place to put the AP based on my experience with other people's systems. People don't have wired Ethernet to their audio rack, so they use an AP behind it and it extends to the main AP. This is kind of a worst case scenario, but it would be very interesting to see if it matters.

My questions are really about everything related to WiFi and HiFi. Sure RF seems to be a bad thing next to audio hear, but also what about components with built-in WiFi? I had a Devialet Expert series set of amps here many years ago and when it wasn't connected to a wireless network, the amps would place the wifi card and antennas internally into blast mode to search for networks. This was easily audible to even the most unlearned listener.

Has anyone noticed that Netflix 4K looks better wired vs wireless?

The adaptive lossy codec makes this test impossible.

Ok, how about 4K flat file? So we aren't dealing with any adaptive bit rate?

Not sure where the content would come from. In addition, it’s a little different because we put the audio signal through an amplifier, which by design amplifies the input. Any anomaly will be amplified. 
 

I don’t know enough about how video works and the internal parts of mass produced televisions, to know what we’d be testing.

I am unaware as to how this would be possible?  Network communications have to be two way, how can a Network over WiFi function if it only has a receiving aspect?  Perhaps there is something which I do not understand here...

Anything is possible, but in this case there needs to be sending and acknowledgment that packets are received. Thus, two-way communication.
