Fibocom FG370 dual-band WiFi 7 and 5G cellular module targets 5G FWA routers

Fibocom FG370 is a compact module that combines WiFi 7 and 5G cellular connectivity designed for 5G FWA routers for the home, SMB (Small and Medium-sized Business), and industrial applications.

Based on the MediaTek T830 quad-core Arm Cortex-A55 SoC, the FG370 supports 5G NR sub-6GHz, two 10Gbps USXGMII interfaces, and dual-band BE7200 WiFi 7 achieving an MLO (Multi-link operation) speed of up to 7.2Gbps.

Note this is not the first “FG370 announcement” from the company, as global operators have used the 5G-only FG370 since October 2023, and the company introduced the FG370 with 5G and tri-band BE19000 WiFi 7 at MWC2024. The company has unveiled a mid-range variant of the FG370 module with 5G and BE7200 at Computex 2024.

The company has yet to release a datasheet for the 5G + WiFi 7 variants, but for reference, here are the Fibocom FG370 (5G-only) specifications: (North American version)

• Interfaces – UART, PCIe 4.0, GPIO, I2S, UIM
• Operating Voltage –  3.3V to 4.4V; typical 3.8V
• Dimensions – 48 x 45 x 2.75mm (LGA package)
• Temperature Range – Standard: -30 to +75°C;  extended: -40 to +85°C
• FCC certifications (NA version)

Drivers are available for Linux 5.4 and the module is supposed to run OpenWrt 21.02. While the model above only supports 5G, we do have some information about the just announced WiFi 7 dual-band model from the press release which looks to be based on the MediaTek Filogic 860 chipset:

• IEEE 802.11be (Wi-Fi 7) standard
• 4K QAM (Quadrature Amplitude Modulation) modulation scheme
• 160MHz channel bandwidth
• Dual-band 2.4GHz 4×4 and 5GHz 5×5 to achieve multi-link speed of up to 7.2Gbps.
• Features – OFDMA, Multi-RU, and MU-MIMO
• 5dB antenna gains

Potential applications for the 5G FWA routers based on the FG370 include 4K/8K video transmission, virtual/augmented reality, cloud gaming, video conferencing, etc… As discussed above there’s limited information about the 5G + WiFi 7 modules, but any details should eventually surface on the FG370 product page.
