The Wi-Fi 6 standard has been officially released, and its emergence will really solve this problem. Compared with Wi-Fi 5, Wi-Fi 6 has 3 times the bandwidth, 4 times the capacity and 1 / 3 delay.

As one of the most important infrastructure, optical fiber broadband has entered hundreds of millions of households. By July 2019, the number of optical fiber broadband users has exceeded 400 million, accounting for 78.3% of 100 megabytes of optical fiber broadband users. 200m broadband is becoming the mainstream package. However, the Wi-Fi experience at home is not as fast as wireless connectivity.

In fact, operators' optical fiber broadband access is only to the information box at the door, and the indoor effect of 5G signal is not good. In indoor scenes, mobile phones, laptops and tablets surf the Internet through Wi-Fi is the mainstream. Compared with 5G, F5G based on 10GPON + Wi-Fi 6 has the characteristics of all-optical connection, ultra-high bandwidth and extreme experience, so it is more suitable for broadband access in home scenarios. If you want to experience the thrill of online car racing in the bedroom, Wi-Fi signals with high bandwidth and good stability are necessary.

From the perspective of current users' home broadband network, only 15% of home networks really have 200m Wi-Fi carrying capacity, and Wi-Fi network has become the bottleneck of broadband speed increase. Statistics from an operator show that about 60% of users' home network problems are related to Wi-Fi. A large part of these problems are caused by the low speed behind the specification of Wi-Fi gateway, the large signal attenuation after passing through the wall, and the serious congestion of neighbor Wi-Fi interference.

The Wi-Fi 6 standard has been officially released, and its emergence will really solve this problem. Compared with Wi-Fi 5, Wi-Fi 6 has 3 times the bandwidth, 4 times the capacity and 1 / 3 delay.

Wi-Fi 6 application scenario 1: Cloud VR video / live streaming is introduced to the home

VR giant screen cinemas, VR live streaming, VR360 °video and so on can give users an immersive experience. Through the combination of OFDMA,MU-MIMO and 1024-QAM technology, Wi-Fi 6 improves the spectrum efficiency of concurrent access and increases the bandwidth of each terminal, giving users an immersive experience.

Wi-Fi 6 application scenario 2: distance learning never leaves home

Enhanced and virtual reality (AR/VR) to enhance the learning experience. Rely on OFDMA, Wi-Fi 6 to provide high throughput, low latency, and network efficiency in dense residential environments to support multiple children in each family to learn through virtual online classrooms. Avoid stutter caused by bandwidth and packet loss, resulting in dizziness and discontinuous teaching experience.

Wi-Fi 6 High capacity Application scenario 3: smart Home IoT Automation Service

It is expected that there will be 5 smart terminals per person in 2025, and 20% of people will have more than 10 smart terminals; the added Wi-Fi network features in Wi-Fi 6 include mechanisms to effectively handle more than 128 terminals and different types of traffic, and provide terminals with higher bandwidth, faster response and more stable connections.

Wi-Fi 6 low latency application scenario 4: let you experience the thrill of online drama anytime, anywhere

Real-time games require very high response delay, and too high transmission delay will affect the synchronization process between the server and the player, resulting in stutters. The slicing technology in Wi-Fi 6 can achieve high-priority dedicated channel bearer, and the BSS coloring anti-jamming mechanism will reduce the probability of interference by 30%, which can also greatly reduce the delay to within 10ms.

2019 is the first year of the launch of Wi-Fi 6, and Wi-Fi 6 will break out in 2020. At present, the Wi-Fi 6 industry chain has become increasingly mature. From home Wi-Fi gateways to terminal devices such as mobile phones and notebooks, Wi-Fi 6 will be supported one after another, which will provide the ultimate experience for VR/ dramas.
