Wi-Fi 7 is the latest Wi-Fi standard, due to be released in 2024, and is designed to deliver faster speeds, lower latency and better performance than its predecessor Wi-Fi 6. IoT gateways are devices that connect IoT devices to the internet and act as a bridge between them and the cloud. In this article, we will discuss the advantages and applications of Wi-Fi 7 in IoT gateways.
One of the main advantages of Wi-Fi 7 is that it uses 320 MHz channel which doubles the bandwidth compared to Wi-Fi 6. It also uses 4096QAM, which results in a 20% increase in bandwidth. Advanced OFDMA increases spectrum efficiency, reduces latency and improves user experience. Spatial doubling helps double network throughput compared to the Wi-Fi 6 version.
Passerelle IoT serves as a bridge between IoT devices and the cloud, providing enhanced security, data processing and connectivity. They perform data aggregation, pre-processing and filtering. They provide local storage such as cache/buffer and edge-level data computation. Have the ability to manage the entire device, device diagnostics and add more functionality.
The new 6 GHz spectrum included in Wi-Fi 6E and Wi-Fi 7 is expected to support higher bandwidth applications such as 8k video and XR displays. It is also expected to improve interference and latency for high-reliability industrial IoT use cases such as factory robotic automation and AGVs. 6 GHz Wi-Fi also improves Wi-Fi positioning accuracy.
In terms of applications, in 2019 Wi-Fi 6 was first introduced by the Wi-Fi access point/router/broadband gateway, the high-end smartphone and the personal computer, which remain the main applications for now. New features, such as TWT (Target Wake Time) and BSS color, benefit IoT devices by adding lower-power operation and better spectrum utilization. Single-band Wi-Fi 6 at 2.4 GHz will have a 13% market share by 2027.
In summary, Wi-Fi 7 is expected to deliver higher speeds, lower latency and better performance than Wi-Fi 6. Passerelles IoT are devices that connect IoT devices to the Internet and act as a bridge between them and the cloud. They perform data aggregation, pre-processing and filtering.
