1 802.11ax: Meeting the demands of modern networks Gopi Sirineni, Vice President Qualcomm Technologies, Inc. April 19,

2 The Wi-Fi landscape has changed More devices & data Diverse apps & services IoT brings more complexity 2

3 A new connectivity model emerged to address new needs Distributed Wi-Fi Powered by Wi-Fi SON Qualcomm Wi-Fi SON is a product of Qualcomm Technologies, Inc. 3

4 60 GHz 5 GHz 2.4 GHz Powerline Self-configuring Self-managing Self-defending Self-healing Qualcomm Wi-Fi SON Transforming in-home Wi-Fi with greater simplicity, coverage and intelligence Qualcomm Wi-Fi SON is a product of Qualcomm Technologies, Inc. 4

5 More dense environments Overlapping channel usage Outdoor and campus Wi-Fi deployments Spectral congestion 5

6 More dense environments Downtown San Francisco Visible APs

7 CAPACITY The most important measure of performance for today s dense networks 7

8 Technology building blocks of 11ax 2.4 GHz 5 GHz OFDMA (Uplink/downlink) More spatial streams 8x8 MU-MIMO (Uplink/downlink) Uplink resource scheduling ac ax Long OFDM symbol 1024 QAM Range extensions BSS color 8

9 OFDMA enables more efficient access Employs proven cellular techniques to make better use of Wi-Fi spectrum OFDM (11n, 11ac) OFDMA (11ax) User 1 (Web page) User 2 (Streaming) User 3 (Instant Mssg) 9

10 OFDMA and MU-MIMO are complementary OFDMA MU-MIMO Increases efficiency Reduces latency Ideal for low-bandwidth applications Increases capacity Higher speed per user Ideal for high-bandwidth applications 10

11 Resource scheduling further boosts efficiency Contention-based resource allocation (11ac) Scheduling based resource allocation (11ax) All devices all compete for resources until they succeed Access point schedules uplink transmissions 11

12 802.11ax: Easing Wi-Fi congestion in dense environments Transportation Hubs High-Rise Apartments Public Venues Enterprises Urban Areas Homes Universities

13 Expands capacity with OFDMA and MU-MIMO 11ax Extends coverage with 8x8 configuration Enhances experiences with greater throughput and Wi-Fi SON 13
