  1. High-DensityWi-Fi DesignTips and Tricks Devin AkinChief Wi-Fi Architect

  2. 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

  3. 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

  4. Design Considerations (cont.) • Designing Around the Facility Characteristics • Leverage RF Obstructions for Channel Reuse • Carefully Consider AP Mounting Locations • Co-locating APs to Increase Capacity • Appropriate Use of Antennas

  5. Network Configuration & Features • Bandwidth Management Techniques • Use WPA2 (AES-CCMP) or Open (no encryption) • Enable WMM & Prioritize Key Applications • Disable Low Data Rates • Minimize Airtime Utilization • Client Rate Limiting

  6. Network Configuration & Features (cont.) • Performance Enhancement Features • Bi-Directional Band Steering • Client Load Balancing • Airtime Fairness and Client SLA Configured Band Steering Ratio

  7. Network Configuration & Features(cont.) • Wired Network Requirements • GigEthSwitch Ports and PoE(+) • RADIUS Server Redundancy • IP Addressing & Subnet Sizing • Internet / WAN Bandwidth • Network Management • On-Premise Management • Performance Monitoring & Tuning 1000 Mbps PoE
