Before designing a wireless network for high-bandwidth applications, you should run a site survey to evaluate the bandwidth requirements of each application to be supported. Proper capacity planning is a key element for success. You need to know what data rate and what bandwidth will be needed in each area of your cell. This implies understanding the bandwidth consumption of each type of frames. One important bandwidth-intensive application is video. This section helps you determine the bandwidth consumption needed by video applications, optimize multicast video traffic with VideoStream, and plan for a migration for 802.11n for increased data rates and throughput.
