Wi-Fi 6, A New Standard

What is Wi-Fi 6 and How fast can it work?

Wi-Fi 6 is a new standard introduced for Wireless Communication. In this article we will try to answer the above questions.

In the world of Wireless Networks, we are familiar with words such as 802.11b, 802.11g, 802.11n, 802.11ac and etc – used for the standards of wireless networking. Fortunately, we will no more face and hear another type of those names. The new standard introduced is 802.11ax and is named as “Wi-Fi 6” which is based on IEEE 802.11 Protocol.

What is Wi-Fi 6?

Before moving to tests, lets become familiar and introduced with the details of the new standard. With the help of new and modern technologies, 10 Gigabit per second is the speed (in theory) we can get from routers supporting Wi-Fi 6. This amount 3x higher than the previous standard 802.11ac speed (in theory). Using the radio frequencies (that were ignored in older generations) along with good management of priorities in QoS (Quality of Service), are among the strengths of the new standard.

For caring and handling the network traffic and congestion, orthogonal frequency division multiple access (OFDMA) modulation is used. OFDMA can support upto 30 clients at the same time by boosting network’s overall capacity and reducing latency. Target Wake Time technology is used to reduce battery usage by determining the device wake up time for sending and receiving data.

How fast is Wi-Fi 6?

We tested the routers on the 2.4GHz band, at close range in the same room, as well as from a 30-foot (10 meters) distance.

2.4GHz Band Testing

As you see in the chart below, All three routers supporting Wi-Fi 6 connected to Laptops Supporting Wi-Fi 6, got higher bands and faster speed compared to AC Client.

The Asus RT-AX88U was 58 percent faster when tested with the 802.11ax client; the Netgear Nighthawk RAX120 was 40 percent faster; and the TP-Link Archer AX6000 was 35 percent faster. The older Asus GT-AC5300 router was the slowest of the four when paired with the 802.11ax-capable Dell, but it improved by 32 percent when paired with the 802.11ac ThinkPad.

Also tested the performance on long-range (10 meters)

The Asus RT-AX88U router delivered a 44 percent increase in throughput when paired with the 802.11ax client versus its score when paired with the 802.11ac client. Similarly, the Netgear RAX120 was 21 percent faster and the TP-Link Archer AX6000 was 45 percent faster when paired with the Wi-Fi 6 client. Once again, the 802.11ac-based Asus Rapture router performed better when paired with an 802.11ac client than it did with a Wi-Fi 6 client.
