2019 is regarded as the first year of WiFi 6 commercial use. Although 2020 was affected by the epidemic, it does not prevent WiFi 6 from being popularized to ordinary household consumers.
Online classes, telecommuting, video conferencing, watching dramas at home, playing games and other online behaviors require faster Wi-Fi 6. The epidemic has promoted the popularity of Wi-Fi 6 on the other side. Especially since the second half of 2019, basically newly released terminal devices such as smartphones and laptops have already supported WiFi 6 technology. It can be said that buying a WiFi 6 router is not a waste.
Compared with the most popular WiFi 5, WiFi 6 is faster, supports more concurrent devices, has lower latency and lower power consumption.
WiFi 6 uses the same OFDMA technology as 5G, combined with 1024-QAM high-order modulation, can support a maximum bandwidth of 160MHz, and the speed is nearly three times faster than WiFi 5. Intelligent frequency division technology can support more devices concurrently and increase the capacity of access devices by 4 times.
Multiple concurrent access devices can reduce queuing, actively avoid interference and coloring, and reduce latency by two-thirds. When the terminal device is in standby, it supports the on-demand wake-up function, which reduces the power consumption of the terminal by 30%.
We can compare the scenario of router to device transmission to a fleet. Under the Wi-Fi i5 standard, the fleet can only be dispatched to one customer at the same time. The convoy was unable to start.
Under the WiFi 6 standard, a convoy starting at the same time can form a team of at least 26 adjacent cars, and each team can be dispatched to different customers. If a car breaks down (disturbed), only the one where it is located will be affected in the squad.
When we are at home, we often find the WiFi signals of our neighbors, and these signals will interfere with our own WiFi transmission. The interference coloring technology used in WiFi 6 can mark neighboring network signal frames passing through the wall, so that the user's router can ignore them.
WiFi signals between neighbors can transmit data on the same channel at the same time without interfering with each other, reducing the interference rate by 30%.
The power consumption comparison between WiFi 6 and WiFi 5 is huge. WiFi 6 will negotiate the timing of WiFi wake-up with the terminal, so that it can wake up on demand, and other sleep times do not consume power.
However, WiFi 5 can only communicate with one device at a time. All terminals connected to the same route are either in a transmission state or in a waiting state, and are disordered, and the waiting state still requires power consumption.
It can be seen that compared with WiFi 5, WiFi 6's technological transcendence is comprehensive. Moreover, the current WiFi 6 routers on the market have reached the price of 200 yuan, which is fully affordable by ordinary household consumers. Major manufacturers are making efforts in the WiFi 6 router market, and the competition in the market will be more intense, but it is a good time for consumers to upgrade WiFi 6 routers.
