At present, remote video conferencing and online classes at home have become mainstream network applications in the home. In the face of the overwhelming number of WiFi 6 routers on the market, whether they really need to upgrade has become a major headache for users. What kind of router is right for you? Let's talk about this topic today.
First, let's take a look at the features of WiFi 6. Compared to the most popular WiFi 5 today, WiFi 6 is faster, supports more concurrent devices, has lower latency, and consumes less power. WiFi 6 uses OFDMA technology that is homologous to 5G, combined with 1024-QAM high-order modulation, to support up to 160MHz bandwidth, nearly three times faster than WiFi 5. Intelligent crossover technology can support more device concurrency and increase the capacity of access devices by 4 times. The multi-concurrent access device can reduce the queuing phenomenon, interfere with the coloring and actively avoid, and reduce the delay by two-thirds. When the terminal device is in standby, the on-demand wake-up function is supported, which reduces the power consumption of the terminal by 30%.
We can compare the scene of the router transmitting to the device as a fleet, under the WiF i5 standard, the departure fleet can only be delivered to one customer at a time, even if there is an empty car, it will start as usual, if there is a car failure (interference), the entire fleet can not start. Under the WiFi 6 standard, a fleet of vehicles departing at the same time can form a squad of at least 26 adjacent vehicles, each team can be sent to a different customer, and if there is a car failure (disturbed), only the squad is affected.
Usually, when we are at home, we often search for the WiFi signals of our neighbors, which will interfere with the Transmission of WiFi in our homes. WiFi 6 uses interference shading technology that marks neighbor network signal frames that pass 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 of WiFi 6 and WiFi 5 is very different. WiFi 6 will negotiate with the terminal wiFi wake-up timing, so that it can wake up on demand, and other sleep times do not consume power. WiFi 5 can only communicate with one device at a time, and all terminals connected to the same route are either in the transmission state or in the waiting state, and it is disordered, and the waiting state still needs to consume power.
It can be seen that WiFi 6 is compared to WiFi 5, and its technical transcendence is all-round. At present, laptops, smartphones, tablets and other products launched in the second half of 2019 have all been equipped with WiFi 6 wireless network cards, if users upgrade the router at home to WiFi 6 routing, they can enjoy a faster WiFi Internet experience. Therefore, it is still necessary to replace the WiFi 6 route.
But if there is no WiFi 6 terminal at home, such as laptops, smartphones, tablets, etc. at home do not support WiFi 6, then upgrading wiFi 6 routers is not necessary.
