- 2. © 2014 AirTight Networks, Inc. All rights reserved. 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 2
- 3. © 2014 AirTight Networks, Inc. All rights reserved. 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 4 Bottom Line 802.11ac provides significantly higher aggregate bandwidth & lower latency compared to 802.11n
- 4. © 2014 AirTight Networks, Inc. All rights reserved. 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 4
