What will Wi-Fi 7 Bring us?

In December 2023, Xiaomi, Huawei, H3C, TPLink and other brands successively released and put on the shelves new products using Wi-Fi 7 technology. At the same time, Xiaomi also released Wi-Fi 7 software updates suitable for old products, allowing domestic consumers to Officially entering the Wi-Fi 7 era.

What is Wi-Fi 7?

As the latest Wi-Fi standard, one of the most notable features of Wi-Fi 7 is its high-speed transmission capability. The technology is expected to support a maximum speed of 30Gbps, which is more than three times the speed of Wi-Fi 6. This is due to more efficient data encoding technology and wider spectrum bandwidth. Wi-Fi 7 supports 320MHz frequency band width, which is significantly improved compared to Wi-Fi 6’s 160MHz. This means more data can be transmitted at the same time, greatly reducing network congestion and latency.

Secondly, Wi-Fi 7 introduces multi-link operation (Multi-Link Operation, MLO, DMLO) technology. This technology allows devices to operate on multiple frequency bands (such as 2.4GHz, 5GHz and 6GHz) simultaneously, enhancing network reliability and flexibility. For example, if one frequency band is interfered with or congested, wireless devices on that band can seamlessly switch to another band, ensuring a stable and smooth data connection.

In addition, Wi-Fi 7 also includes more advanced modulation technologies, such as 4096-QAM. This technology can transmit more data in the same radio waves, further improving the efficiency and throughput of the network. The low latency characteristics of Wi-Fi 7 can also provide a smoother and more responsive user experience.

To put it simply, Wi-Fi 7 not only focuses its technology on speed, but also makes special optimizations for wireless signal anti-interference. Although this does not fundamentally solve the problem of Wi-Fi signal attenuation through walls, in an era of Internet of Everything with more and more wireless devices, Wi-Fi 7 does have its own unique features.

What does Wi-Fi 7 mean for the average consumer and enterprise user?

For ordinary consumers, the high speed and low latency characteristics of Wi-Fi 7 will greatly improve the wireless experience of the home internal network (the part behind the optical modem), including 8K wireless live broadcast, high-speed wireless download and even wireless VR streaming. will become possible. In addition, the high capacity and stability of Wi-Fi 7 can also ensure that the home network can still maintain stability when multiple devices are used at the same time, which is more friendly to smart home users.

For enterprise users, Wi-Fi 7's high-speed data transmission capabilities can change the way files are transferred and shared within the company. The low-latency feature also makes real-time collaboration and remote meetings more convenient. In industrial environments, Wi-Fi 7 can support more complex robots and automation systems to improve production efficiency. In addition, for places that require high-density network connections, such as conference centers or stadiums, improvements in Wi-Fi 7 will bring a more reliable network experience.

How to use Wi-Fi 7?

If the hardware supports it, you can enable Wi-Fi 7 by waiting for the corresponding system update. If the device does not support Wi-Fi 7, Wi-Fi 6 devices can also "passively" experience some Wi-Fi 7 network features under certain circumstances.
