"Two 2.0 stations can cover an area around 6m x 6m depending on the environment and the coverage of the stations."
This agrees with the documentation included with the Vive Pro headset.
"The stations themself have a 6m range"
This does not agree with the documentation, or with your previous sentence.
In order to "cover an area around 6m x 6m," wouldn't the base stations have to be placed further than 6m apart? This is basic geometry.
What I'm asking about (and what I think the OP was asking about originally) has exactly zero to do with the range of the HMD tether. It is about the playspace that SteamVR lets you set up, which does not change for a tethered or untethered setup.
Additionally, while it's true that "not everybody using Pro is using 2 stations," the image shown in the documentation included with the Vive Pro kit, which includes 2 stations, depicts 2 stations and a max range of 6m x 6m.
Also, you seemed to cut off your thought there mid-sentence. Did you have more to say after "there's quite a bit of"?
You are correct that nothing in the image refers to a "6m range." That quote is from your earlier post in this thread, which is what I was replying to. My entire point was that your post made nearly a year ago disagrees with documentation included with a kit I purchased a few months ago.
Again, I would like to ask why this discrepancy exists, as well as why there isn't more up-to-date documentation available for a device that has been out for over a year.
