RG255C-GL 概述
A 5G RedCap (Reduced Capability) module is a class of cellular IoT transceiver defined in 3GPP Release 17 that provides reduced-bandwidth, power-efficient 5G NR connectivity between full 5G modems and low-power LTE Cat-M/NB-IoT devices. Within the wireless connectivity hierarchy, RedCap sits under 5G NR within cellular wide-area networks, alongside LPWA technologies, making it a middle tier of the power-management and data-rate spectrum for IoT.
Key features of the RG255C-GL include 5G LAN, URLLC and network slicing support, an integrated Qualcomm IZat location technology Gen 9VT GNSS receiver covering GPS, GLONASS, NavIC, BDS, QZSS and Galileo, and global band coverage (the GL variant) for wide multi-region deployment. The integrated GNSS receiver simplifies product design and provides quicker, more accurate and more dependable positioning without a separate positioning chip.
The module is powered by Qualcomm RedCap platform silicon and supports rich host interfaces including USB, PCIe and UART, allowing integration into both embedded host processors and gateway designs. Support for URLLC and slicing enables industrial-grade latency and QoS segmentation on 5G SA networks, while LTE Cat 4 fallback ensures connectivity where 5G SA coverage is not yet available.
Typical applications include industrial gateways and routers, battery- or plug-in-powered IoT devices, video surveillance backhaul, and smart-grid or telematics units that need mid-rate 5G with low power consumption. The GL variant is certified for global deployment, as evidenced by T-Mobile IoT device certification for the US market.
Design consideration: the RG255C series is specified for industrial and commercial applications only, and system designers should plan antenna routing and thermal design around the LGA land pattern per the Quectel hardware design guide.

典型应用
RG255C-GL 适用于 6 应用s: Industrial IoT Gateways and Routers, Battery-Powered IoT and Asset Tracking, Video Surveillance Backhaul, Smart Grid and Utility Communications, Telematics and Fleet Management, Networking CPE and Fixed Wireless Access.
Industrial IoT Gateways and Routers
Industrial gateways demand wide-area 5G connectivity with deterministic behavior and long service life. The RG255C-GL fits this role because its 3GPP Rel-17 RedCap design delivers 223 Mbps downlink and 123 Mbps uplink, sufficient for aggregated sensor traffic and remote configuration, while URLLC and network slicing allow QoS-segmented industrial traffic on 5G SA networks. The module connects to the host CPU via USB, PCIe or UART, enabling straightforward integration into x86 or ARM gateway boards. Because it is industrial-grade and falls back to LTE Cat 4, deployments keep connectivity during 5G SA rollout gaps. Designers should follow Quectel's hardware design guide for antenna matching and power supply layout.
推荐
Battery-Powered IoT and Asset Tracking
Battery- and plug-in-powered IoT devices require mid-rate cellular data without the power budget of full 5G. The RG255C-GL's RedCap architecture reduces modem complexity and power draw while still providing up to 123 Mbps uplink, adequate for periodic telemetry bursts, image upload and firmware over-the-air updates. The integrated Qualcomm IZat Gen 9VT GNSS receiver (GPS, GLONASS, NavIC, BDS, QZSS, Galileo) eliminates a discrete GNSS chip, reducing BOM cost and quiescent drain, and provides quicker, more accurate positioning for tracking use cases. LTE Cat 4 fallback guarantees coverage in areas without 5G SA. Sleep-mode current and PSM behavior should be validated against the Quectel specification during battery sizing.
推荐
Video Surveillance Backhaul
IP cameras and NVR backhaul links need sustained uplink throughput more than peak downlink. The RG255C-GL's 123 Mbps uplink comfortably carries multiple H.265 video streams, and URLLC support stabilizes latency for real-time viewing. The Sub-6 GHz SA operation with LTE Cat 4 fallback keeps surveillance sites online across mixed coverage. Because the module mounts as an LGA SMD device, it integrates directly into camera PCBs rather than occupying a card slot, saving enclosure space. The GL variant's global band coverage simplifies multi-country surveillance product SKUs. Integrators should provision slicing on carrier networks where surveillance traffic needs isolation from consumer traffic.
推荐
Smart Grid and Utility Communications
Smart-grid RTUs, distribution automation terminals and metering concentrators benefit from 5G SA network slicing, which the RG255C-GL supports alongside URLLC, giving utilities QoS-isolated communication channels over public networks. The 223 Mbps downlink handles firmware distribution to field fleets, while LTE Cat 4 fallback maintains availability during grid-area coverage transitions. The module's industrial-grade rating and wide integration of GNSS (BDS and GPS included) support synchronized field devices. The CN variant is often preferred for Chinese grid deployments, while GL covers mixed international utility estates. Compliance with regional utility emission and isolation standards must be validated in the end-equipment design.
推荐
Telematics and Fleet Management
Fleet telematics units combine positioning, driver-connectivity and cloud reporting. The RG255C-GL integrates Qualcomm IZat Gen 9VT GNSS with GPS, GLONASS, NavIC, BDS, QZSS and Galileo, giving dependable positioning without a second RF chipset, and its 123 Mbps uplink supports CAN-bus data upload, dashcam clip transfer and OTA updates. The LGA SMD package withstands vibration better than card-edge connectors when properly soldered per the Quectel hardware design guide. LTE Cat 4 fallback ensures reporting continuity in rural corridors lacking 5G SA. Note that the series is industrial/commercial grade, so passenger-car AEC-Q100 requirements must be assessed separately by the system integrator.
推荐
Networking CPE and Fixed Wireless Access
Entry-level fixed wireless access (FWA) CPE and backup-WAN routers can use RedCap where full 5G throughput is unnecessary. The RG255C-GL provides 223 Mbps downlink, matching entry broadband tiers, with PCIe or USB attachment to the CPE main board. Its 5G LAN feature enables local Ethernet-style device grouping behind the CPE, and slicing support allows service providers to segment residential and business traffic. The global-band GL variant reduces SKU count for multi-market FWA products. Thermal design should account for sustained transmit duty in outdoor enclosures, and antenna placement should follow the Quectel reference design to preserve Sub-6 GHz MIMO performance.

设计说明
The RG255C-GL mounts as an LGA SMD module; follow Quectel's Hardware Design Guide for pad geometry, keep-out zones and RF feed layout. RF antenna traces should be 50-ohm controlled impedance with matching network placement near the antenna pad as shown in the reference design. Avoid routing high-speed USB/PCIe pairs under the module's RF section, and provide solid ground return vias around the module land pattern. The module is available in M.2 and Mini PCIe derivatives (e.g., RG255CGL00AB-4M2-M20AA) if a connectorized approach simplifies your manufacturing.
The RG255C series is industrial and commercial grade only - do not deploy it in automotive applications without separate qualification review. Verify the orderable suffix carefully: RG255C-GL is the LGA module, while RG255CGL00AB-4M2-MN0AA / M20AA are Mini PCIe and M.2 derivatives with different mechanical fit. Also confirm carrier band and certification coverage per region; the GL variant covers global bands but regional variants (CN/NA/EU) may be the certification-cleanest choice for single-region products.
Estimated: RedCap modems draw substantially less peak current than full 5G modems, but 5G SA burst transmit still creates current transients on the VBAT rail; size the supply for the peak current given in the Quectel hardware design guide [DATA_NEEDED: peak supply current] and place bulk capacitance close to the module supply pins. For battery designs, evaluate PSM/eDRX behavior with your carrier's network configuration, as idle current is dominated by network paging cycles rather than the modem itself.
合规信息
