Introduction to 802.11ac802.11n vs. 802.11ac


Agenda

• Beyond the Hype: 11ac’s True Benefits

• Where 11ac Can Really Help

• How they Stack Up: 11n vs. 11ac

• Should You Catch Wave 1 or Wait for Wave 2?

• Greater Scalability = Cost Savings: 11n vs. 11ac

• 11ac Clients Everywhere You Look

• AirTight Networks C-75

• The Big Payout

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
