QCA9984 SoC

Wave-2 802.11ac Solution with MU-MIMO and 160MHz for Home Networks

The QCA9984 is a Wave-2 802.11ac radio that helps premium Wi-Fi routers, gateways, set-top boxes and range extenders to support more devices and more demanding applications in the connected home. The dual-band, 4x4 solution is designed to deliver peak data rates up to 1.7 Gbps, and uses Multi-User MIMO to maintain fast connections on increasingly crowded networks. The QCA9984 also supports 160MHz and 80+80MHz channels to double capacity at close range.

QCA9984 is a product of Qualcomm Technologies, Inc., and/or its subsidiaries.
