AP Density Calculator

Calculate access point density and spacing for WiFi deployments

Total floor area to be covered by WiFi. Include hallways and common areas if they need coverage.
Expected number of simultaneous WiFi users per 1000 sq ft (or per 100 sq m). Office: 20-40. Lecture hall: 100-200. Warehouse: 5-10.
users/1000sqft
Minimum guaranteed throughput per user. Web browsing: 2-5 Mbps. Video calls: 5-10 Mbps. Streaming: 15-25 Mbps.
Mbps
Practical throughput per AP after overhead. WiFi 6 AP: 400-600 Mbps typical. WiFi 5 AP: 250-400 Mbps. WiFi 4 AP: 100-150 Mbps.
Mbps
Maximum recommended client count per AP. Cisco recommends 25-50 for WiFi 5, up to 60 for WiFi 6. Depends on AP model and traffic type.
