FG40 / FG50 4G/5G Cellular Communication Module

Key Features

The FG40 / FG50 Series provides cellular connectivity for robot remote control, telemetry, video transmission and mobile IoT applications. FG40 is the 4G LTE version, while FG50 adds Sub-6 GHz 5G SA / NSA support.

1. FG40 4G & FG50 5G Cellular Connectivity

Choose FG40 for 4G LTE connectivity or FG50 for higher-bandwidth Sub-6 GHz 5G. Both modules are designed for robots, mobile platforms, remote monitoring, telemetry and industrial IoT applications.

2. Multi-Network Coverage

FG40 supports LTE together with 3G / 2G fallback networks. FG50 supports 5G SA / NSA and is backward-compatible with supported 4G / 3G networks, helping maintain connectivity when the highest-generation network is unavailable.

3. FG40 Interfaces & SIM Integration

FG40 provides USB and UART communication, including a Type-C connector and XH1.25 4-pin serial debug connector. It supports SIM / USIM cards and provides power and network status indicators.

4. FG50 Interfaces & Power

FG50 provides USB networking through Type-C 3.0, a dedicated 12 V DC power input, SIM slot, reset button, and power / network status indicators for system integration.

5. High-Bandwidth 5G for Video & Remote Operation

FG50 is the preferred option for HD video backhaul and other bandwidth-intensive remote-operation scenarios. Peak rates reach up to 2.2 Gbps downlink / 575 Mbps uplink in NSA mode and 2 Gbps downlink / 1 Gbps uplink in SA mode.

6. Technical Specifications

FG50 supports Sub-6 GHz 5G, LTE and UMTS, together with Windows, Linux and Android. Supported networking methods include RNDIS / ECM / NCM. Actual throughput depends on carrier coverage, network load, SIM plan and signal conditions.

7. Long-Range Robot Communication

Cellular connectivity can extend robot monitoring, telemetry and remote-control links beyond local Wi-Fi coverage. End-to-end latency and reliability depend on the carrier network, routing architecture and robot-side software.

8. Mechanical Integration

The modules use CNC-machined metal enclosures with mounting holes for installation on robots, vehicles and industrial equipment. FG40 is the smaller and lighter option, while FG50 uses a larger enclosure and multiple antenna connections for 5G operation.

Carrier Compatibility Notice

SIM card is not included. Before overseas deployment, confirm that your local carrier's supported LTE / 5G frequency bands match the module configuration. Actual speed and coverage depend on the carrier, SIM plan, signal strength, network congestion and antenna installation.

Frequently Asked Questions

What is the difference between FG40 and FG50?

FG40 is the 4G LTE model and supports LTE together with 3G / 2G fallback networks. FG50 is the 5G model and supports Sub-6 GHz 5G SA / NSA together with 4G / 3G compatibility.

Which model should I choose for a robot?

Choose FG40 when standard 4G bandwidth is sufficient and you want a smaller module with USB / UART connectivity. Choose FG50 for higher-bandwidth applications such as HD video transmission, multi-camera remote monitoring or other applications that benefit from 5G.

Can FG50 work when there is no 5G signal?

FG50 is compatible with supported 4G and 3G networks, so it can fall back when 5G is unavailable, subject to local carrier bands and network service.

What are the maximum data rates?

FG40 supports LTE-FDD speeds up to 150 Mbps downlink and 50 Mbps uplink. FG50 supports up to 2.2 Gbps downlink / 575 Mbps uplink in 5G NSA mode and 2 Gbps downlink / 1 Gbps uplink in 5G SA mode. Real-world performance will normally be lower and depends on the carrier network and deployment conditions.

Which operating systems are supported?

Both models list support for Windows, Linux and Android.

What interfaces are available?

FG40 provides USB and UART, including a Type-C connector and XH1.25 4-pin serial debug connector. FG50 provides USB networking through Type-C 3.0 and uses a separate 12 V DC power input.

What power supply is required?

FG40 requires at least 5 V / 2 A with a 10 W power requirement. FG50 requires at least 12 V / 1 A DC.

Is a SIM card included?

No. A compatible SIM / USIM card must be prepared separately.

Will the module work in my country?

It depends on the local carrier frequency bands. Before ordering for international deployment, compare your carrier's LTE / 5G bands with the supported bands listed in the product specifications.

Can I use an IoT SIM card?

A compatible carrier SIM or IoT SIM can be used, but some SIM cards restricted to specific software, devices or private-network applications may not be compatible. Confirm with your carrier if your SIM has such restrictions.

Can the module be used for remote robot control?

Yes. Cellular networking can be used as the communication link for remote robot control and telemetry. End-to-end control latency depends on the carrier network, server architecture, VPN or routing method, and robot-side software.

Can it transmit live video?

Yes. Both models can be used for IP-based video transmission. FG50 is the preferred option for higher-resolution or higher-bitrate streaming when 5G coverage is available.

What are the module dimensions and weight?

FG40 is approximately 78.6 × 37 × 15.6 mm and 65 g, excluding the antenna. FG50 is approximately 90 × 60 × 20.8 mm and 120 g, excluding antennas.

How is the module mounted?

Both modules use CNC metal enclosures with mounting holes. Mechanical drawings provide the relevant mounting dimensions for integration into a robot or equipment enclosure.
