The DECT Base (Digital Enhanced Cordless Telecommunications) refers to a type of wireless communication system typically used in cordless telephones and other wireless communication devices. It uses a base station (or "DECT base") to communicate with DECT handsets, allowing for long-range, high-quality wireless communication. In the context of Windows drivers, a DECT Base driver would refer to the software required for your computer to recognize and interact with a DECT-based wireless device (e.g., a cordless phone, headset, or a base station that connects to your PC).

Depending on the device, the DECT Base could be associated with different types of hardware (e.g., a DECT USB dongle, a DECT phone, or a wireless headset) that interacts with your PC via a USB port, Bluetooth, or another wireless communication method.
