Compared to WiFi 5, where is WiFi 6 better?
Take a family of three as an example. Two adults often need to
participate in video conferences when working from home, and children need to
take online classes at home. Internet speeds are often rushed, making remote
video conferences and online classes poor experience.
At present, remote home office work and class have become
the new normal.

And as gigabit broadband enters the home, upgrading WiFi 6
routers has become the choice of many users.
Judging from market data, 2020 has become the first year of
the popularization of WiFi 6.
In the post-epidemic era, network behaviors such as remote
video conferencing, remote office work, and online classes have become the new
normal. As a result, family demand for WiFi 6 routers will continue to grow.
The policy of speed-up and fee-reduction continues, and the
speed of home broadband has been further increased. Currently, it has started
at 300M and capped at 1000M. With the further popularization of high-speed
broadband to households, the slogan of building a "three gigabit"
network was put forward on Telecom Day.
Among them, WiFi 6 routers take on the important task of
gigabit home wireless broadband. Major operators and joint manufacturers have
produced WiFi 6 customized optical modems and routers, which further boosted
the popularity of WiFi 6 routers.
But many friends said that they still don’t understand what
is the best WiFi 6 compared to the current WiFi 5? And why should I upgrade to
WiFi 6 routing?
Let's take a look at the features of WiFi 6. Compared with
the most popular WiFi 5, WiFi 6 is faster, supports more concurrent devices,
lower latency, and lower power consumption.
WiFi 6 uses OFDMA technology that is the same 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.
The access devices are more concurrent, which can reduce the
queuing phenomenon, actively avoid interference coloring, and reduce the delay
by two-thirds. When the terminal device is on standby, it supports the
on-demand wake-up function, which reduces the terminal power consumption by
30%.
We can compare the scenario transmitted by the router to the
device as a fleet. Under the WiF i5 standard, the fleet can only be dispatched
to one customer at the same time. Can't start.
Under the WiFi 6 standard, a fleet of vehicles departing at
the same time can form a team of at least 26 adjacent vehicles. Each team can
be dispatched to different customers. If a vehicle fails (disturbed by
interference), it will only affect the location. Squad.
Usually when we are at home, we often search for neighbors'
WiFi signals, and these signals will interfere with our own WiFi transmission.
The interference coloring technology adopted by WiFi 6 can
mark the neighbor network signal frames coming 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%.
There is a huge difference between the power consumption of
WiFi 6 and WiFi 5. WiFi 6 will negotiate with the terminal on the timing of
WiFi wake-up, so that it can wake up on demand, and it does not consume power
during other sleep times.
However, WiFi 5 can only communicate with one device at a
time, and all terminals connected to the same route are either in a
transmission state or in a waiting state, and they are disordered, and the
waiting state still requires power consumption.
It can be seen that compared with WiFi 5, WiFi 6 has a
comprehensive technical transcendence.
At present, laptops, smartphones, tablets and other products
launched in the second half of 2019 are all equipped with WiFi 6 wireless
network cards. If users upgrade their home routers to WiFi 6 routers, they can
enjoy faster WiFi Internet access. Experience.
Therefore, it is necessary to replace the WiFi 6 router.
However, if there is no WiFi 6 terminal in the home, there is no need to
upgrade the WiFi 6 router.
