Setup: must have Guest Wi-Fi Physically Separate from Corporate Wi-Fi.
Implication: Additional horizontal Cat-6 cables and additional APs exclusively dedicated to Guest APs.
Not talking about the VLans segregation classic solution here
Q1: Shall we use the existing site survey(Corporate) for Guest APs positioning to add the new Guest APs next to the existing corporate APs ?
if Yes, what about interference between the pair of APs ?
Q2: Would appreciate if you could provide a white paper/guide lines or high level design example on how to setup such requirement.
If the customer mandates to do taht and don't attend experts advice, then the solution would be to provide Guest wireless over 2.4 GHz band, and the rest of access over 5GHz and 6GHz bands, this way you don't need to worry about co-channel interference, and lack of performance.
This is the only way to go, as co-locating APs for Guests over the ones for Corporate access and using the same bands it's crazily out-of any best practice, and out of any performance logic.
Thank you all for your feedback.
In fact it's my initial reply to the department who is pushing for physical Wi-Fi traffic segregation. They argue that some sites have this setup.
Thank you again. Case is closed.
