EG25-G 概要
An LTE Cat 4 module is a cellular communication device that provides fourth-generation mobile broadband connectivity for machine-to-machine systems. In the product hierarchy it sits as: cellular module -> LTE modem -> wireless transceiver module -> IoT connectivity component. LTE Cat 4 defines a UE capability class with 150 Mbps peak downlink and 50 Mbps peak uplink, sufficient for most IoT gateways, routers, and telematics units that do not require Cat 6 carrier aggregation speeds.
Key features include the 150 Mbps/50 Mbps Cat 4 data rates, a unified LGA footprint compatible with the Quectel EC2x series (EC25, EC21, EC20 R2.1), the EG21-G LTE module, and the UC200T UMTS/HSPA+ series, and a rich set of industry-standard interfaces including USB with drivers for Windows, Linux, and Android.
Technically, EG25-G adopts 3GPP Release 11 LTE technology and supports a broad set of Internet protocols, making integration with host processors straightforward. Firmware and regional variant management (for example -G global, -GL, -GGB, -GGC, -GGD suffixes) allows one PCB design to serve multiple regional certification requirements.
Typical applications include industrial LTE routers and gateways, in-vehicle telematics units, IoT trackers and smart meters, and embedded systems such as the Pine64 PinePhone, which ships with the EG25-G as its cellular modem.
Design consideration: the module is compatible with the EC2x unified footprint, but data rates, band support, and fallback (2G/3G) behavior differ between LTE-only EG25-G and multi-mode EC25 variants - verify regional variant suffix before release. USB_VBUS should be powered from a 5 V system for USB detection per the Quectel reference design.

主な用途
EG25-G の用途: 6 件s: Industrial LTE Routers and Gateways, In-Vehicle Telematics and eCall, IoT Trackers and Smart Meters, Embedded Linux SBCs and Single-Board Computers, Security Cameras and Video Surveillance Uplink, Global IoT Device Deployment (Multi-Regional SKU).
Industrial LTE Routers and Gateways
Industrial routers require reliable, always-on cellular backhaul for remote sites, PLC networks, and SCADA systems. The EG25-G fits this role with LTE Cat 4 throughput of 150 Mbps downlink and 50 Mbps uplink, which is sufficient to aggregate multiple Ethernet devices and support VPN tunnels without becoming the bottleneck. Its 3GPP Release 11 compliance ensures carrier interoperability, and the 29.0 x 32.0 x 2.4 mm LGA footprint with unified Quectel pinout lets one router PCB accept LTE-only (EG25-G) or multi-mode (EC25) modules depending on regional 2G/3G sunset plans. The USB 2.0 host interface with native Linux drivers simplifies integration with embedded Linux router SoCs, and 1.8 V GPIO domains plus 5 V USB_VBUS wiring follow the Quectel reference design directly.

In-Vehicle Telematics and eCall
Automotive telematics units, fleet trackers, and eCall terminals benefit from the EG25-G's Android/eCall driver support and Cat 4 data rates, enabling real-time GPS position reporting, video evidence upload, and over-the-air firmware updates. The 150 Mbps downlink supports dashcam video offload while 50 Mbps uplink handles continuous telematics streaming. Because the module uses the unified EC2x-compatible LGA footprint, a telematics control unit can be designed once and populated with EG25-G (LTE-only) or EC25 (with 3G fallback) depending on the destination market's legacy network availability. Compliance with 3GPP Release 11 and Quectel's mature field deployment history - noted by engineers migrating from EC25-EU to EG25 variants for global coverage - reduces certification risk in fleet programs.
おすすめ
IoT Trackers and Smart Meters
Battery-constrained and cost-sensitive IoT devices such as asset trackers, smart meters, and vending telemetry terminals use the EG25-G where Cat 4 bandwidth is needed only occasionally but connectivity must be dependable. The module's rich Internet protocol stack offloads TCP/IP handling from the host MCU, and standard AT command control keeps host firmware simple. The compact 29.0 x 32.0 x 2.4 mm LGA package fits space-limited enclosures, and footprint compatibility with the Cat 1 EC21 allows product families to trade peak bandwidth (150 Mbps EG25-G) for lower module cost and power (EC21) on the same PCB. ANT_MAIN and ANT_DIV antenna interfaces, controllable via Quectel AT commands, support diversity reception in metal meter cabinets where signal margin is tight.
おすすめ
Embedded Linux SBCs and Single-Board Computers
Single-board computers such as the Pine64 PinePhone ship the EG25-G as their cellular modem, demonstrating mature mainline-adjacent Linux support. Quectel publishes USB drivers for Linux and Android alongside Windows, and the module's Internet protocol suite integrates with standard network managers (ModemManager/NetworkManager workflows). For SBC designers, the EG25-G connects over USB 2.0 with VBUS powered from the board's 5 V rail and VBUS_CTRL used for power gating, while the 1.8 V interface domain requires level shifting to 3.3 V hosts per the Quectel reference design. Peak rates of 150 Mbps downlink and 50 Mbps uplink make the module suitable for mobile hotspot and failover-WAN functions in portable and battery-powered computers.
おすすめ
Security Cameras and Video Surveillance Uplink
Cellular-backhauled security cameras need uplink bandwidth for live streaming; the EG25-G's 50 Mbps uplink comfortably carries multiple 1080p H.264 streams with headroom for cloud recording. The 150 Mbps downlink supports remote viewing, PTZ control, and firmware updates simultaneously. Deployed in the unified Quectel LGA footprint, camera NVR and cellular gateway designs can interchange EG25-G, EC25, and EC20 R2.1 modules to match regional carrier requirements without PCB respins - a documented benefit of the EC2x compatible form factor. The module's 3GPP Release 11 LTE technology provides the low-latency packet handling expected in surveillance trigger events, and Windows/Linux driver support eases integration with both embedded NVR SoCs and PC-based recording stations.

Global IoT Device Deployment (Multi-Regional SKU)
OEMs deploying one hardware platform across many countries use the EG25-G family's variant system (-G global, -GL, -GGB, -GGC, -GGD regional suffixes) to satisfy regional band plans and carrier certifications from a single PCB. Because all variants share the 29.0 x 32.0 x 2.4 mm unified LGA footprint with the EC2x, EG21-G, and UC200T series, a device can ship as LTE Cat 4 in developed markets, drop to Cat 1 (EC21) or 3G (UC200T) where economics demand it, and add 2G/3G fallback (EC25) where legacy networks persist. Quectel forum engineers migrating from EC25-EU to EG25 variants for global coverage cite field maturity of the -G variant as a decisive selection factor. This variant strategy minimizes SKU proliferation while keeping antenna, power, and USB design identical across regions.

設計ノート
LTE modules draw high burst currents during RF transmission. Per the Quectel EG25-G Reference Design, the interface domain is 1.8 V and USB_VBUS should be powered from a 5 V power system for USB detection, with VBUS_CTRL used to switch VBUS. Size the 3.8 V-class main supply for LTE Cat 4 transmit bursts (several amps peak; consult the hardware design guide V1.5 for the exact budget) and place bulk capacitance close to the VBAT pins to prevent brownout-induced resets during PA bursts.
Route the USB 2.0 differential pair as 90-ohm matched-length traces between host and the EG25-G, keeping stubs short. If the host MCU GPIO domain is 3.3 V, insert level translation on UART/GPIO lines because the EG25-G interface domain is 1.8 V per the Quectel reference design. Keep the ANT_MAIN and ANT_DIV 50-ohm RF traces away from the USB pair and power rails, and verify antenna matching on the final PCB stack-up.
Variant suffixes matter: -G, -GL, -GGB, -GGC and -GGD differ in band support and regional certification, and EG25-G is LTE-only with no 2G/3G fallback. Designers migrating from EC25-EU have reported needing careful variant analysis (Quectel forums, 'Selection between EG25-G or EC25-GL'). Verify the target carrier's band plan against the specific variant datasheet before ordering, and confirm whether embedded applications need the EC25 multi-mode part instead.
