Fibocom says its FG550-EAU 5G module now runs on 4Gb of LPDDR4x memory. The earlier configuration used 8Gb. That is a 50 percent cut in RAM capacity, announced on June 23, 2026, during MWC Shanghai.
The company stated that the module keeps its business functions and customer-specific customization. It is built on the Samsung Exynos Modem platform.
The context is a tight memory market. Fibocom says AI server and data center demand has intensified shortages and price swings, and that memory cost and availability have become key factors in bringing 5G terminals to market. Using less RAM, it argues, lowers terminal bill-of-materials costs and makes delivery more certain in mass production.
How Fibocom did it
The work was software. Fibocom reviewed low-level code, changed how memory is scheduled and allocated system resources more precisely, based on what terminals actually need in operation. It says that made a stable deployment possible with the 4Gb configuration, and that the module’s resource utilization, operating experience and power efficiency improved.
The FG550-EAU supports 3GPP Rel.16 and NR 5CC carrier aggregation. It is backward compatible with LTE Cat.20, covering 4G and 5G dual-mode connectivity across mainstream global networks.
Xuebao Pan, senior vice president and head of the System LSI R&D Center at Samsung Semiconductor China Research, called the partnership with Fibocom “strong and enduring.” He said Samsung looked forward to more joint work “to empower next-generation 5G terminals.”
Fibocom plans to work with global FWA, mobile broadband and IoT customers on terminals that cost less and arrive on schedule. The company is the first Chinese wireless module maker listed on both the A-share and H-share markets.
