On March 5, during the 2025 Mobile World Congress (MWC Barcelona 2025), Fibocom and MediaTek jointly demonstrated the technical performance of the FG370 module based on the MediaTek T830 platform, featuring Modem AI and 3Tx (3-antenna transmission) + L4S (Low Latency, Low Loss, and Scalable Throughput). These features meet the product development needs of global leading operators for 5G FWA (Fixed Wireless Access) and MiFi (Mobile Broadband) in their respective application scenarios, including precise network prediction, intelligent network selection strategies, and optimized air interface performance.
Fibocom FG370, equipped with MMAI (MediaTek Modem AI), significantly enhances network connection efficiency in four weak-signal scenarios: high-speed railways, underground environments, airports, and remote suburban areas. In airports, AI-driven network prediction improves network search speed by over 50%. In outdoor mobile scenarios, MMAI provides an AI hiking mode, optimizing weak-signal and high-power consumption issues, resulting in a 10% energy saving for devices. In high-speed railway scenarios, Fibocom 5G AI module with MMAI ensures faster and more stable terminal connectivity, while in underground environments, it enables rapid 5G network recovery.
Most connected terminals support only two transmission chains, which greatly limits uplink throughput. Fibocom FG370, applied in 5G FWA and MiFi, utilizes 3Tx technology to support three transmission chains, significantly boosting peak uplink throughput. According to Fibocom’s lab tests, compared to 2Tx, 3Tx can increase throughput by up to 68% by adding spatial streams. The L4S technology provides terminals with a low-latency, low-packet-loss, and scalable throughput network experience. Tests show that combining 3Tx and L4S delivers 1.9 times the bandwidth of 2Tx while significantly reducing latency.
Additionally, The FG370 5G AI Module supports 8Rx and 3GPP Rel-17 standards, including HUPE TDD PC2/PC1.5 and FDD PC2 communication capabilities, greatly improving signal quality at the cell edge and enhancing throughput. Fibocom assists global leading operators in rapidly developing 5G FWA and MiFi products, reducing development costs while improving efficiency. Based on user needs, Fibocom will continue to develop and support key 5G technologies, enabling the widespread adoption of 5G FWA and MiFi in more scenarios.
