Fibocom has taken a module it already sold and made it run on half the working memory. That is the claim at the center of a company announcement issued on June 23, 2026, during MWC Shanghai 2026, where the Chinese module maker introduced the FG550-EAU.
The FG550-EAU is a 5G module built on the Samsung Exynos Modem platform. According to Fibocom, its RAM was trimmed from LPDDR4x 8Gb to LPDDR4x 4Gb, a 50% cut in capacity. The company said the module keeps its business functions and the customer-specific customization that buyers rely on.
Why memory is the pressure point
Fibocom framed the change around the market. Demand from AI servers and data centers, it said, has tightened memory supply and made prices swing, and that has turned the cost and availability of memory into a deciding factor for companies trying to bring 5G terminals to market. In the company’s telling, a smaller memory footprint should lower the bill of materials for customers, make supply more resilient and give them more certainty when they deploy.
Those are Fibocom’s own projections, and the announcement gave no pricing or shipment figures.
How the company says it did it
Fibocom said the work was driven by what real terminals actually need. Its engineers reviewed low-level code, reworked memory scheduling and allocated system resources more precisely, which the company said allows stable operation with the 4Gb setup. It also said the optimized module keeps its key product features while improving resource use, the user’s operating experience and power efficiency. The announcement did not include test data to back those statements.
What the module does
On the radio side, the FG550-EAU supports 3GPP Rel.16 and NR 5CC carrier aggregation. It is backward compatible with LTE Cat.20 and handles 4G and 5G dual-mode connectivity across mainstream global networks, Fibocom said.
Samsung’s side of the partnership got a mention too. Xuebao Pan, senior vice president and head of the System LSI R&D Center at Samsung Semiconductor China Research, was quoted in the release: “Samsung Exynos Modem and Fibocom share a strong and enduring partnership.” He said Samsung values the “breakthrough in balancing performance and cost” and looks forward to continuing the collaboration on next-generation 5G terminals.
Who it is aimed at
Fibocom said it will keep drawing on its 5G connectivity, platform adaptation and supply chain management skills to work with customers in fixed wireless access, mobile broadband and IoT. The goal, as the company puts it, is 5G terminal products that cost less to build and arrive more reliably.
The company describes itself as China’s first wireless communication module maker listed on both the A-share and H-share markets. For device builders squeezed by memory costs, the open question is whether a module with 4Gb performs as well in the field as Fibocom says it does. The announcement offered no independent test results.
