Deploying Secure 802.11 Wireless Networks with Microsoft Windows
Performance
When designing for performance, use the following best practices:
Do not overload your wireless APs with too many connected wireless clients. Although most wireless APs can theoretically support hundreds of wireless connections, the practical limit is 20 25 connected clients, due to the effective bandwidth usable by each wireless client.
For higher-density situations, lower the signal strength of the wireless APs to reduce the coverage area, thereby allowing more wireless APs to fit in a specific space and more wireless bandwidth to be distributed to more wireless clients.
To minimize the authentication and authorization latency of wireless authentication requests, install IAS on domain controllers.
