Beyond the Hype: 11ac’s True Benefits
• Effectively quadruple per radio capacity: 160 MHz vs. 11n/40 MHz
• More bits per MHz: 33% increase 256-QAM vs. 11n/64-QAM
• Double per radio capacity: Up to 8 spatial streams vs. 4 with 11n
• Higher average data rates/greater range: Standardized explicit beamforming (TxBF)
• Switch-like functionality: MU-MIMO supports up to 4 simultaneous transmissions
• More efficient MAC layer: Larger frame aggregation

Bottom Line802.11ac provides significantly higher aggregate bandwidth
& lower latency compared to 802.11n

Where 11ac Can Really Help
Greenfield• Wave 1 technology is here now• Wave 2 is 1.5 – 2 years out and initial improvements over Wave 1 incremental • 802.11n will ensure obsolescence before refresh cycle

Use Case 11n(40 MHz)
11ac Wave 1(80 MHz)
Single Radio Throughput(5 GHz only)
96 Mbps*(11n 2x2 clients)
277 Mbps*(11ac 2x2 clients)
Multi AP Throughput(Single interference zone, DFS,
US)
1.7 Gbps*(11n 2x2 clients, 12 unique 40
MHz channels)
2.6 Gbps*(11ac 2x2 clients, 6 unique 80 MHz
channels)
Max Client Density(4 APs, 3 Mbps SLA)
128 Clients*(11n 2x2 clients, 40 MHz)
232 Clients**(11ac 2x2 clients, 80 MHz)
Video Streaming (1 AP, 3 Mbps video via HTTP)
15 Tablets(11n 1x1 tablets, 40 MHz)
58 Tablets11ac 2x2 tablets, 80 MHz
Greater Scalability = Cost Savings: 11n vs. 11ac
*Estimated moderate density (16 - 30 clients active simultaneously) aggregate throughput capacity = 32 % max data rate**Estimated very high density (46 - 60 clients active simultaneously) aggregate throughput capacity = 20 % max data rate
