Fibocom has launched the FG550-EAU, an optimized 5G module based on the Samsung Exynos Modem platform with enhanced memory solutions. While fully retaining core business functions and customer customization capabilities, the Fibocom 5G module‘s RAM specification has been optimized from 8Gb LPDDR4x to 4Gb LPDDR4x, achieving a 50% reduction in memory capacity.

Addressing the demands for cost control and stable delivery in 5G terminal mass production, this solution helps customers reduce terminal BOM costs and strengthen supply chain resilience. It provides a more predictable and reliable component selection for large-scale commercial deployment.
Precision Memory Optimization: Balancing Cost and Performance
Currently, driven by the demand for AI servers and data center construction, the global memory chip supply remains tight, accompanied by intensified price volatility. As a critical component of communication modules, the cost and supply stability of memory directly impact the overall hardware costs and mass production schedules of 5G terminals.

In response, Fibocom has conducted precision memory optimization for the FG550-EAU. Through comprehensive bottom-level code review, memory scheduling strategy reconstruction, and refined system resource allocation, Fibocom successfully resolved issues such as underlying adaptation conflicts, memory footprint control, multi-branch code management, and functional trimming risks, achieving stable deployment of the 4Gb specification.
The optimized FG550-EAU retains key functional features and customer customization capabilities while improving system resource utilization efficiency, ensuring both optimal terminal operation experience and power consumption performance.
From a supply chain perspective, 4Gb LPDDR4x is a mature, standardized, and widely used component with a broader supply base and guaranteed production capacity. Combined with Fibocom’s diversified supply chain system, this solution effectively reduces reliance on single high-specification memory components, enhancing batch delivery and long-term supply assurance.

High-Speed Connectivity and Open Adaptation: Supporting Multi-Scenario Terminal Deployment
Even with the optimized memory configuration, the Fibocom FG550-EAU fully maintains its core communication capabilities for high-performance 5G terminals. Supporting the 3GPP Rel.16 standard, the module features high data rates, low latency, and high reliability. It is adaptable to diverse application scenarios, including 5G FWA, mobile broadband, industrial communications, HD video transmission, and whole-home broadband.
In terms of transmission performance, the FG550-EAU supports NR 5CC multi-carrier aggregation and is backward-compatible with LTE Cat.20 full-band specifications. It enables seamless 4G/5G dual-mode switching, adapting to mainstream 4G/5G network environments worldwide.
For device development and system adaptation, the FG550-EAU features an open architecture design. It has successfully completed joint debugging and adaptation with mainstream AP application processor solutions from Broadcom and Realtek, helping customers shorten the R&D, debugging, and mass production cycles for FWA terminals.

This memory configuration optimization for the FG550-EAU represents Fibocom’s technological innovation practice centered around customers’ mass production needs. Looking ahead, Fibocom will continue to leverage its 5G communication capabilities, platform adaptation expertise, and supply chain management skills. By partnering with global FWA, mobile broadband, and pan-IoT customers, Fibocom aims to create 5G terminal products with greater cost competitiveness and delivery certainty, accelerating the transition of various industries from the “Internet of Everything” to the “Intelligent Internet of Everything.”
