Fibocom has taken half the memory out of one of its 5G modules. The FG550-EAU, shown at MWC Shanghai 2026, carries 4Gb of LPDDR4x RAM where the earlier configuration carried 8Gb.
The company’s reason is supply. According to Fibocom, demand from AI servers and data centers has made memory chips scarce and their prices unsteady, and that now bears directly on what it costs to build 5G devices and how fast they ship.
The module sits on Samsung’s Exynos Modem platform. Fibocom says the cut did not cost it business functions or the customer-specific customization it offers. To get there, it said, engineers reviewed low-level code, reworked how memory is scheduled and tightened the allocation of system resources. The result, the company says, is better resource use, operating experience and power efficiency.
The 4Gb part also helps on the buying side. Fibocom describes it as mature, standardized and widely used, with a broader supply base and guaranteed production capacity. Fewer customers have to compete for a single high-specification chip. The company says this lowers the bill of materials for terminals and gives makers more certainty on delivery.
What the module does
The FG550-EAU supports 3GPP Rel.16 and NR 5CC carrier aggregation. It is backward compatible with LTE Cat.20 and runs in both 4G and 5G modes on mainstream networks worldwide. Fibocom lists fixed wireless access, mobile broadband, industrial communications, HD video transmission and whole-home broadband as target uses.
It has been tested with application processors from Broadcom and Realtek, which Fibocom says shortens development and debugging for FWA terminals.
Xuebao Pan, a senior vice president at Samsung Semiconductor China Research, welcomed the work. “We highly value this breakthrough in balancing performance and cost,” he said.
No field results for the 4Gb version have been published. Everything above comes from Fibocom’s own announcement.
