The Dell Wireless 5620 (EV-DO-HSPA) Mobile Broadband Mini-Card NMEA is a mobile broadband card used to connect to cellular networks (such as EV-DO or HSPA) for mobile internet access on compatible devices. This type of card is commonly used in laptops, netbooks, or other portable devices to provide mobile data services when a Wi-Fi connection isn't available. The NMEA part refers to the National Marine Electronics Association standard used for GPS data communication, meaning the card may also have GPS functionality, but it mainly serves as a broadband connection device.
