Supports Wi-Fi, Bluetooth, and complex chipsets like Ralink and Atheros.

The concept of Compat Wireless emerged in the early 2000s, when the need for wireless interoperability became increasingly important. In the past, wireless technologies were often proprietary, limiting device compatibility and creating "islands" of connectivity. The idea of Compat Wireless was to create a standardized, open technology that would allow devices from various manufacturers to communicate with each other.

Extract it:

Typically, Linux drivers are integrated directly into the kernel source tree. This means that if a developer writes a high-performance driver for a new Ralink RT3572 chipset, it might only be available in Linux kernel version 5.x or higher. Users on an enterprise-grade "stable" kernel (like version 3.x or 4.x) would normally be unable to use that hardware without upgrading their entire operating system—a task that is often risky or impossible for production environments.
