What is Wi-Fi 7?

When Wi-Fi 7 will ready?

As mobile communications entered the 5G era in 2018, Wi-Fi also entered the sixth generation – Wi-Fi 6 in the same year. The transmission rate is not much different from 5G, and it has the advantage of low latency, making Wi-Fi 6 a complementary technology in the 5G communication environment, and launching a higher specification Wi-Fi 6E technology in 2020. However, technological progress will never stop. While Wi-Fi 6/ Wi-Fi 6E has just become the mainstream technology in the market, the latest generation of technology, Wi-Fi 7, will come out in 2023.

The benefit of Wi-Fi 7 - Faster, lower latency, and more reliability.

In terms of throughput, Wi-Fi 7 has increased from 9.6Gbps of Wi-Fi 6 to 46.1Gbps; in terms of bandwidth, it has doubled, from 160MHz to 320MHz, and doubled the speed by doubling the bandwidth; at the same time, Wi-Fi 7 has also increased from the original 8x8 MIMO to 16x16, bringing double the traffic and capacity.
In the past, traditional Wi-Fi devices could only use a single connection to transmit data, however, Wi-Fi 7 has added MLO, which enables the device to transmit and receive data simultaneously across multiple frequency bands and channels, resulting in lower latency and more reliable connections; Wi-Fi 7 also brings the new Preamble Puncturing technology. Through this technology, the frequency bands that were previously busy and cannot be fully used can be opened without causing waste of channels, and introduce the Multi-RU to effectively improve resource utilization
