For a high-client device turnover and a large number of highly mobile devices, the recommendation should center on the adequate provisioning of resources to handle the increased demand and processing load. This scenario, with a high number of clients and frequent roaming, particularly stresses the hardware's processing capabilities. Therefore, additional hardware resources beyond those recommended for a typical AirWave platform are necessary to ensure optimal performance and reliability, making it the appropriate change to recommend.

The number of required Air Monitors (AMs) in a network is generally based on the ratio to Access Points (APs). In an environment with 20 APs per floor, normal density would suggest one AM for every four APs, which leads to approximately 5 AMs. In a high-density environment, fewer AMs are needed per AP, around one AM for every seven to ten APs, resulting in about 2 to 3 AMs. Balancing these considerations, the recommended range is about 3 to 5 AMs per floor to ensure adequate coverage and monitoring. This range covers both normal and high-density scenarios effectively.

The solution that meets the customer requirements of terminating VPN tunnels for Aruba RAPs with a single public IP address and N+1 redundancy is to use two Aruba MCs on the same subnet that use VRRP without clustering. This setup avoids the need for each controller in a cluster to have a unique public IP, which the customer does not have. VRRP provides the necessary redundancy while allowing the IPsec traffic to be forwarded to the correct device.

Voice applications have the greatest potential impact on RF design because they typically require consistent, low-latency connectivity to maintain call quality. They are more sensitive to issues like interference, coverage gaps, and poor signal strength compared to other applications such as print, email, or secure web browsing.
