Hi team, I am doing one proposal for customer on Wirelss design, how to adopt APs, L3 or L2, thin Ap or AAp using WAN. but, my customer needs to know some case study for reference. My customer has many sites in diferent regiones. I think there two ways to design in such situation. 1.all switches in HQ and AAp distributed to others, certralized management 2.distribute the switches to each of sites, seperately management So, if anyone has implemented any big Wireless cases (adoption via Lan or Wan), pls kindly share to me. The more case study, the more opp. we win. Thanks a lot zhiguo
