  5. 5. 5QUALCOMM ATHEROS RESTRICTED – NDA Single-User MIMO Serves one device at a time Multi-User MIMO Multi-user beamforming (MUBF) serves multiple devices simultaneously Spatial re-use multiplies available capacity (2-3x) Reduces wait time for all clients
  6. 6. 6QUALCOMM ATHEROS RESTRICTED – NDA MU-MIMO for increasingly crowded home networks The average home has 7 connected devices – projected to be >20 devices by 2020 MU–1sMU–1s Improves throughput, latency and power consumption for all clients 11ac devices with MU-MIMO o Router speaks to groups of MU devices o Up to 3 simultaneous MU devices per group Legacy devices (single-user MIMO) o Still served individually by the router o Benefit from increased airtime availability
  7. 7. 7QUALCOMM ATHEROS RESTRICTED – NDA Benefits of Multi-User MIMO (vs Single-User) 2.5x Improvement in UDP throughput per client (shown at Close Range – MCS9/256QAM) SU-MIMO (Three 1-stream clients) 4x4APCapacity(Mbps) 350 (1-stream @ MCS9) Each user gets ~117 Mbps (350÷3) 1s SU 1s SU 1s SU MU-MIMO (Three 1-stream clients, in an MU group) 910 (3-streams @ MCS9) Each user gets ~303 Mbps (910÷3) 1s MU 1s MU 1s MU 4x4APCapacity(Mbps) 1s MU 1s MU 1s MU 1s MU 1s MU 1s MU Time Time
  8. 8. 8QUALCOMM ATHEROS RESTRICTED – NDA MU-MIMO (Three 1-stream clients, in an MU group) 450 (3-streams @ MCS4) Each user gets ~150 Mbps (450÷3) 1s-MU 1s-MU 1s-MU 170 (1-stream @ MCS4) Each user gets ~57 Mbps (170÷3) 1s-SU 1s-SU 1s-SU SU-MIMO (Three 1-stream clients) Benefits of Multi-User MIMO (vs Single-User) 2.6x Improvement in UDP Throughput per Client (shown at Mid Range – MCS4/16QAM) 4x4APCapacity(Mbps) 4x4APCapacity(Mbps) Time Time 1s-MU 1s-MU 1s-MU 1s-MU 1s-MU 1s-MU
  9. 9. 9QUALCOMM ATHEROS RESTRICTED – NDA With 2-3x greater efficiency for MU clients, the network has more “free” time/capacity to serve other clients.
