The Wi-Fi Alliance is expanding its certification program to include "wave 2" features, including:
MU-MIMO: Networks with MU-MIMO are capable of multitasking by sending data to multiple devices at once rather than one-at-a-time, improving overall network efficiency and throughput
160 MHz channels: Wi-Fi CERTIFIED ac increases the maximum channel bandwidth from 80 MHz channels to 160 MHz channels, potentially doubling transmission speeds
Four spatial streams: Device speeds are proportional to the number of spatial streams. Wi-Fi CERTIFIED ac now includes support for four spatial streams, up from three spatial streams.
Extended 5 GHz channel support: Wi-Fi CERTIFIED ac encourages device support for a greater number of available channels in 5 GHz. Support for additional channels makes more efficient use of available spectrum and reduces interference and congestion by minimizing the number of networks operating on overlapping channels.
“In today’s world, people have more Wi-Fi devices per person and per household, and those devices require significantly more bandwidth,” said Edgar Figueroa, president and CEO of Wi-Fi Alliance. “Wi-Fi Alliance updated the Wi-Fi CERTIFIED ac program to meet increasing user demands and to stay ahead of emerging applications, while preserving interoperability.”
The first Wi-Fi CERTIFIED ac products to support new features and which comprise the test bed for interoperability certification are:
- Broadcom BCM94709R4366AC
- Marvell Avastar 88W8964
- MediaTek MT7615 AP Reference Design and MT6632 STA Reference Design
- Qualcomm IPQ8065 802.11ac 4-stream Dual-band, Dual-concurrent Router
- Quantenna QSR1000 4x4 802.11ac Wave 2 Chipset Family
