Design Considerations
• Determining Required Capacity› Client Device Types and Quantity› Targeted Application Throughput
(per User/Device)
• Key RF Design Principles› Leverage 5 GHz Bands For Capacity› Primarily Use 20 MHz Channel Widths› Create a Balanced Link with Clients

Design Considerations (cont.)
• Site Surveying is a MUST› Types: Predictive, Active, Passive› Pre-Deployment and Post-Deployment› Cell Sizing to Maximize SNR› Maintain Clients at High Data Rates› Minimize CCI / ACI
