5G RedCap

Linux Cellular Networking and Advanced Modem Integration

Modern embedded systems, industrial IoT platforms, routers, gateways, and edge computing solutions increasingly rely on seamless integration between Linux operating systems and LTE/5G cellular technologies. As operators transition towards 5G Standalone (SA) networks and 3GPP Release 17 introduces Reduced Capability (RedCap) devices, engineers must understand not only cellular networking fundamentals but also Linux networking, modem management, IPv6 adoption, dual-SIM architectures, and practical troubleshooting techniques.

This intensive one-day technical workshop provides participants with the knowledge required to design, deploy, integrate, and troubleshoot Linux-based cellular networking solutions using current industry practices and emerging technologies. Recent developments in 3GPP Release 17 and Release 18 have expanded RedCap capabilities for industrial IoT, wearables, gateways, and edge devices, making this knowledge increasingly relevant for modern deployments.

The course is delivered by an instructor with over 30 years of industry experience, using practical, real-world implementation techniques and deployment scenarios that reflect current industry requirements rather than purely academic concepts.
