The evolution of 5G is entering a new phase. While early deployments focused on enhanced mobile broadband (eMBB) for high-speed consumer applications, the next wave of growth is being driven by industrial IoT, smart infrastructure and connected devices that require balanced performance, efficiency, and scalability. At the centre of this shift is 5G Reduced Capability (RedCap) technology, defined under 3GPP Release 17, which is designed to bridge the gap between high-end 5G modules and lower-speed LTE solutions.
Quectel’s RG255C-NA and RM255C-GL modules represent a strategic move into this fast-growing segment, delivering Sub-6 GHz 5G connectivity optimised for mid-tier IoT applications. By combining reliable throughput, reduced complexity and improved power efficiency, these modules provide an ideal solution for industrial and commercial deployments transitioning to 5G.
Understanding the role of 5G RedCap
RedCap technology is engineered for devices that do not require the extremely high data rates or antenna complexity of traditional 5G eMBB modules, but still benefit from 5G’s lower latency, network slicing, and long-term scalability. Typical applications include smart meters, industrial automation systems, telematics units, asset trackers, gateways, and fixed wireless access (FWA) devices.
With theoretical peak data rates of up to 223 Mbps downlink and 123 Mbps uplink, the RG255C-NA and RM255C-GL deliver more than sufficient bandwidth for these use cases. At the same time, RedCap reduces hardware complexity by lowering bandwidth requirements and RF design overhead, resulting in more cost-effective and power-efficient deployments.
Both modules support 5G Standalone networks and maintain backward compatibility with LTE, ensuring seamless operation in areas where 5G coverage is still expanding.
Two form factors for diverse integration needs
Although the RG255C-NA and RM255C-GL share a common technology platform, they are designed for different integration strategies.
The RG255C-NA comes in a compact LGA package measuring
The RM255C-GL, in contrast, adopts a widely used M.2 form factor
Industrial-grade performance
Designed with demanding environments in mind, both modules support an operating temperature range of -30°C to 75°C, with extended temperature options available for harsher industrial settings. This makes them suitable for outdoor installations, utility infrastructure, and transportation systems.
The modules incorporate advanced 5G features including:
• Ultra-Reliable Low Latency Communication for time-sensitive applications.
• Network slicing, enabling dedicated logical networks for specific services.
• 5G LAN support, allowing 5G to function as a virtual local area network.
• Device Firmware Over-the-Air for remote updates and lifecycle management.
Optional multi-constellation GNSS support – including GPS, GLONASS, Galileo, BeiDou, QZSS and NavIC – adds precise positioning capability, expanding their suitability for fleet management, logistics, and tracking solutions.
The RG255C-NA and RM255C-GL provide a comprehensive range of interfaces, including USB 2.0, PCIe 2.0, UART, (U)SIM, SPI, and PCM. Driver support is available for Windows, Linux, and Android platforms, complemented by Quectel’s enhanced AT command set. This ensures flexibility across development environments and simplifies system design.
The RG255C-NA and RM255C-GL provide OEMs with flexible hardware options and a future-proof migration path toward 5G. Whether integrated directly onto embedded boards via LGA or deployed in modular gateway designs via M.2, these modules offer a scalable, standards-compliant solution aligned with the next generation of connected infrastructure.
