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.

 

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 speed is often rushed, making remote video conferences and online classes poor experience.

 

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.
