Technology Overview
The Qualcomm® Gobi™ 2000 is a second-generation multi-mode 3G mobile broadband solution designed to provide high-speed internet access across global cellular networks. Based on the MDM2000 (Mobile Data Modem) architecture, this module was the industry's first to offer truly "world-mode" capability on a single PCI Express Mini Card, supporting both HSPA and EV-DO networks.
The Gobi 2000 technology utilizes a software-defined radio approach, allowing the module to load specific firmware images based on the inserted SIM card. This enables seamless roaming and carrier switching without hardware modifications. Integrated Standalone and Assisted-GPS (A-GPS) capabilities provide precise location-based services, making it a cornerstone for enterprise-level mobile computing from 2009 to 2013.

Implementation Notes
Deployment of Gobi 2000 modules in Linux environments requires the qcserial and qmi_wwan drivers. Please ensure that the proprietary firmware images (amss.mbn, apps.mbn, etc.) are placed in the /lib/firmware/gobi/ directory before initializing the hardware interface via ModemManager.
