Wi-Fi 5 is out! Wi-Fi 6 advantages: faster speed/more power efficient

If 2019 is the first year of Wi-Fi 6 commercialization, then 2020 is undoubtedly the year when Wi-Fi 6 begins to gradually become popular among consumers.

Although we are still in the epidemic period, a number of routers and terminals that support Wi-Fi 6 have been officially released in the past few months.

Now, Huawei, Xiaomi, TP-LINK, ASUS, and Netgear have all released their own Wi-Fi 6 wireless routers. Should you change one during the May Day holiday?

Compared with the most popular Wi-Fi 5, Wi-Fi 6 is faster, supports more concurrent devices, has lower latency, and consumes less power.

Wi-Fi 6 uses the same OFDMA technology as Huawei 5G, combined with 1024-QAM high-order modulation, and can support a maximum bandwidth of 160MHz, which is nearly three times faster than Wi-Fi 5.

Intelligent frequency division technology can support more devices concurrently and increase the access device capacity by 4 times.

Accessing more devices concurrently can reduce queues, actively avoid interference, and reduce latency by two-thirds.

When the terminal device is in standby mode, it supports on-demand wake-up function, which reduces terminal power consumption by 30%.

We can compare the scenario of router transmitting to device to a fleet. Under the Wi-Fi 5 standard, a fleet can only deliver to one customer at the same time. Even if there are empty cars, they will be dispatched as usual. If a car breaks down (is interfered with), the entire fleet cannot be dispatched.

Under the Wi-Fi 6 standard, a fleet of vehicles setting out at the same time can form a small team of at least 26 adjacent vehicles. Each team can be sent to different customers. If a car breaks down (is interfered with), it will only affect the team it is in.

When we are at home, we often detect our neighbors’ Wi-Fi signals, which can interfere with our own Wi-Fi transmissions.

The interference coloring technology used by Wi-Fi 6 can mark neighboring network signal frames that pass through walls, allowing users' routers to ignore them.

Neighbors’ Wi-Fi signals can transmit data simultaneously on the same channel without interfering with each other, reducing the interference rate by 30%.

The power consumption of Wi-Fi 6 and Wi-Fi 5 is very different. Wi-Fi 6 will negotiate with the terminal on the timing of Wi-Fi wake-up to achieve on-demand wake-up, and no power will be consumed during other sleep times.

Wi-Fi 5 can only communicate with one device at a time. All terminals connected to the same router are either in a transmission state or in a waiting state, and they are disorderly. The waiting state still consumes power.

In general, Wi-Fi 6 routers are the general trend, and the prices of many products have dropped below 300 yuan. If your mobile phone or laptop supports Wi-Fi 6, you can really consider trying it!
