Quectel Wireless Solutions has announced an LGA version of its RG660Qx 5G communications module, designed to facilitate the shift from legacy GSM-R to the Future Railway Mobile Communication System (FRMCS). The hardware and a companion evaluation kit are intended for device-level interoperability testing.
Why it matters
As the rail industry modernizes its communication infrastructure, this module provides the necessary technical foundation for testing advanced, high-bandwidth 5G network performance. It accelerates the transition for operators moving to FRMCS standards while ensuring backward compatibility.
The module integrates Qualcomm X85 and X82 5G Modem-RF systems and achieves Ethernet speeds up to 10 Gb/sec. It utilizes Power Class 1.5 to provide extended signal coverage and supports n100 and n101 frequency bands.
The players
Quectel Wireless Solutions
An international supplier of IoT modules and connectivity hardware specializing in cellular and satellite modem integration.
Qualcomm
A global semiconductor company that designs and supplies the 5G Modem-RF system-on-chip architectures used in the RG660Qx series.
The details
Quectel developed the module in an LGA (Land Grid Array) format—a surface-mount packaging method where connection pins are located on the bottom of the chip—to improve mechanical stability and support interoperability testing. The system includes an evaluation kit, a hardware platform that allows engineers to test device-level performance before full-scale deployment. By supporting Power Class 1.5, the hardware transmits at a higher power level than standard units to maintain connectivity over wider geographic rail areas.
