I need to configure 3 piece of R710 access point for a one day outdoor meeting event for estimate 800 or 900 people at outdoor. There is no rf pollution in the environment, the meeting area is outside the city and far from any settlement and wireless broadcast will be unencrypted. I will mount the access points to the 3 tower and the form is scalene triangle. Please advice me setup tip of the unleased setup. Should I edit each access point radio channels individual? And how can limit the user of the each access point client? Or more experienced ideas?
