The Wi-Fi Alliance industry group, the body that certifies Wi-Fi products to enable interoperability, has expanded the ?Wi-Fi CERTIFIED ac? certification program to include features for faster performance. The ?Wave 2? upgrade to 802.11ac brings with it better multitasking, doubles the channel bandwidth and extends support for 5GHz connections which boost up internet speeds and especially benefit the gaming community.
One of the most anticipated features wrapped up in the latest upgrade is the Multi-User Multiple Input Multiple Output (MU-MIMO) support, which allows more devices to operate on the same network without a drop in performance, reports SlashGear. While MIMO is already an element of 802.11ac, MU-MIMO builds on it with the ability to more effectively multitask when dealing with several wireless devices.
This means that rather than sending data to one device at a time, MU-MIMO is able to transmit to multiple devices at once, so you’re less likely to suffer slow download speeds when other devices are hooked on to the same Wi-Fi. Wave 2 brings immense benefits to the gaming community as the game streaming will become far more faster even with several devices such as laptops, mobiles, tablets and consoles are hooked to the Wi-Fi.
Normally, wireless routers rapidly switch between clients, transmitting to them one at a time. As the number of clients increases, the delay involved while waiting for your device to get its ?turn? in the queue can introduce latency in how fast webpages respond or how smooth video or game streaming is. With MU-MIMO, routers are able to communicate to multiple devices simultaneously, meaning no waiting time.
Other than MU-MIMO, maximum channel bandwidth has increased from 80 MHz to 160 MHz with the Wi-Fi 802.11ac Wave 2 update. There’s also an additional spatial stream, an increase from three to four compared to the previous standard, and wider support for 5 GHz channels, reducing interference and congestion by cutting down on the number of networks using overlapping channels and offering the potential to double transmission speeds.
So consumers looking foward to get the new Wave 2 Wi-Fi certified devices should always look for the Wi-Fi CERTIFIED logo to ensure the best user experience possible. For more information and a list of Wi-Fi CERTIFIED ac products, you can check out: www.wi-ficertifiedac.com.
