Comparing WiFi 6 and WiFi 5, the difference lies in these three items.

Many friends around 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? Just look at the comparison below!




The shopping festival has come. If you want to grab the discounted products you have long wanted, you need fast internet speed to support! Excluding the factor of external network bandwidth, the WiFi connection between the mobile phone and the wireless router is very important. At present, WiFi 6 routers are already the main sales force of major e-commerce websites, but there are still many users who are still using WiFi 5 wireless routers.

Even many friends said, why suddenly it was called WiFi 5 and WiFi 6? In fact, WiFi 5 is the original 802.11ac wireless protocol, and WiFi 6 is the latest 802.11ax wireless protocol. In 2019, when the 802.11ax protocol was officially certified, the WiFi Alliance officially named the 802.11ax wireless protocol as the WiFi 6 wireless protocol. In addition, the previous generation of wireless protocols are analogized in turn, namely WiFi 5 (802.11ac), WiFi 4 (802.11n)...




First, 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 of the router to the device transmission to a fleet. Under the WiF i5 standard, the fleet can only be dispatched to one customer at the same time. None of the teams can 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 in power consumption between 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. All terminals connected to the same route are either in a transmission state or in a waiting state, and they are disordered. 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.
