WiFi Alliance intros 802.11 AC Wave 2 Spec

The new wireless standard also sends data to multiple devices at the same time!

The WiFi alliance just introduced the new 802.11 ac wave 2 specification today. It can potentially double the previous version’s transmission speeds. Devices can achieve this by its controller that increases the channel bandwidth from 80 MHz to 160 MHz.  The MU-MIMO (Multi-User multiple input multiple output) is also a new function. It enables the WiFi-AC routers to send data to multiple devices at the same time rather than one device at a time.

The other features this new spec supports are as follows:

  • 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.”

Supported WiFi Chipsets:

  • 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 4×4 802.11ac Wave 2 Chipset Family

The Wireless AC Wireless routers are available. But it’s uncertain if existing models can provide full support for wave 2. There’s no update about the 802.11 ad specification as of now.
