Modem Gsm Csd
Overview
Product sourcing insights & recommendations
The market for GSM CSD (Circuit Switched Data) modems is currently in a terminal phase, characterized by a global migration toward IP-based technologies like LTE Cat M and NB-IoT. While legacy hardware like the Siemens MC35 remains available for maintenance, rising operational costs and the 2G sunset (scheduled between 2025–2030 in many regions) make CSD increasingly obsolete for new industrial deployments.
I have compiled a comprehensive market trend and insights report covering technical migration paths, pricing for modern alternatives, and strategic sourcing recommendations. The report details how utility companies and SCADA operators are transitioning to 5G-ready industrial modems while maintaining support for legacy serial protocols (RS232/RS485).
You can review the full analysis, including product comparisons and regional network status, in the document below.
The GSM CSD market is rapidly transitioning. You can proceed with:
