The ZTE Mobile Broadband NMEA Port Windows Driver is a driver associated with ZTE mobile broadband devices, such as USB modems, mobile hotspots, or dongles, that provide cellular network connectivity (3G, 4G, etc.) for your computer. The NMEA Port specifically refers to the National Marine Electronics Association (NMEA) protocol, which is typically used for GPS data transfer. In the context of mobile broadband devices, the NMEA port driver is responsible for enabling the communication between your device and the operating system for the GPS functionality or other data transfer capabilities offered by the device.

For example, many ZTE USB modems come with built-in GPS functionality, which would use the NMEA protocol to share GPS data with applications like mapping or navigation software. The ZTE Mobile Broadband NMEA Port driver ensures that the GPS data from the mobile broadband device is correctly communicated to Windows via a virtual COM port (the NMEA port).
