Compex “JustWiFi⁷™” driverless, Ethernet-connected Wi-Fi 7 module delivers up to 10 Gbps throughput (Sponsored)

Compex JustWiFi7 vs WiFi7 dual band dual concurrent module

Compex Systems (Compex) is redefining how wireless is integrated into modern embedded and industrial systems with the launch of JustWiFi⁷™, a one-of-a-kind, driverless, tri-band concurrent Wi-Fi 7 module that connects through Ethernet protocols. Designed to eliminate the complexity of traditional wireless integration, JustWiFi⁷™ makes high-performance Wi-Fi deployment faster, simpler, and smarter. Rethinking Wi-Fi Integration: No Drivers. No Hassle. JustWiFi⁷™ Most of the Wi-Fi modules today rely on PCIe, SDIO, or USB interfaces and are controlled through drivers. Developers will need to deal with the drivers’ compatibility with the host platform, particularly its OS and kernel version. The drivers for Wi-Fi 7 are particularly complex due to the standard’s advanced features. Many open-sourced drivers and sometimes the host CPU are not able to deliver the full capabilities of the Wi-Fi 7 chipset. These complications often unnecessarily slow down and add to the development time and effort. Engineered for speed, simplicity, and […]
