3 QUALCOMM ATHEROS RESTRICTED – NDA

First wave of 11ac made Gigabit Wi-Fi possible

3x faster than 11n

− Up to 1.3 Gbps (3-stream)

− Wider channels (80 MHz)

− Data encoding (up to 256 QAM)

Mandatory 5GHz band

− More (and wider) channels

− Less interference

Lower power-per-bit

− Extends battery life

− Mobile devices communicate

more quickly and sleep longer

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

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
