On a large campus wireless network (approx. 500 APs, 4-5000 connected devices) we have been asked to create an SSID for some specific equipment that can only work on the 2.4Ghz range. No problems with that. The company that supplies the devices has come in to do a wireless survey in the area where they will be deployed and we have failed the survey for, amongst other things, these two points (with a screenshot of the survey underneath).
- The Operating Mode not being Greenfield or Legacy. I am bit unsure what this means (even after research) so any help would be greatly appreciated. My limited understanding of it though is that this can't be expected of an established campus network. Is that right?
- Our channel width is set to 20Mhz when it should be 40Mhz, 80Mhz or 160Mhz. Now I think this is for 5Ghz isn't it? 2.4Ghz is set to 22Mhz and that is it? Are they completely wrong here?
I haven't raised this with the supplier yet because they benefit from us signing off on a failed survey. I'd rather say 'this is wrong' than ask 'is this wrong?'.
Many thanks for any help you could provide.
