A network architect is creating a new wireless solution for a customer. Wireless coverage is required throughout all four floors of two buildings on the same campus. Dynamic RF capabilities, including AirMatch, are required. Seamless roaming is required within and between the two buildings. Each floor will have approximately 20 APs and 6 external APs are required for connectivity between the two buildings. Given this information, which Aruba solution would be the most cost-effective while still meeting the customer's requirements?
