Fibocom Cuts 5G Module Memory Load to Stabilize Supply Chains

Unveiled at MWC Shanghai 2026, the optimized module shifts from an 8Gb to a 4Gb LPDDR4x configuration. Fibocom engineers achieved this by conducting deep-level code reviews and refining memory scheduling to ensure the system remains stable despite the reduced capacity. This shift directly targets the current supply chain squeeze, where surging demand for AI servers has driven up both the price and scarcity of high-end memory components.

Beyond cost management, the FG550-EAU retains support for 3GPP Rel.16 and NR 5CC carrier aggregation, ensuring backward compatibility with LTE Cat.20. Xuebao Pan, senior vice president at Samsung Semiconductor China Research, credited the breakthrough to Fibocom’s engineering precision in balancing performance with manufacturing constraints. The move signals a broader industry trend toward hardware efficiency as companies seek to secure delivery certainty for 5G, FWA, and IoT deployments.
