The 5G chips use the in-development 802.11ac standard.

Broadcom

• BCM4360 supports the PCIe interface and implements 3-stream 802.11ac specifications, and reaches speeds up to 1.3 Gbps.

• BCM4352 and BCM43526 implement 2-stream 802.11ac specification to reach up to 867 Mbps. BCM4352 supports PCIe interface; BCM43526 supports the USB interface.

• BCM43516 supports USB and reaches speeds of up to 433 Mbps with its single stream 802.11ac implementation.

All four models use the 80 MHz channel and a technology called beamforming, which uses specific receivers to increase the operational range.
