The Quectel PCI Express Windows driver is a software package designed to enable communication between a Quectel PCIe (PCI Express) cellular module (or wireless card) and a Windows-based computer or server. Quectel manufactures a variety of modules used for cellular connectivity, including 4G LTE, 5G, and other wireless communication technologies. These modules are typically installed on a PCIe interface in desktop PCs, servers, or embedded systems.

The driver allows your system to recognize and interface with the Quectel PCIe card, enabling it to work with Windows networking features, and to use the cellular network for internet connectivity, SMS, voice, and other services supported by the Quectel device.
