CradlePoint MC400 modem — cellular modem, upstream 5.76 Mbps, downstream 42.2 Mbps, 256‑QAM, silver, 104 g

The CradlePoint MC400 modem is a compact cellular modem engineered for integration with compatible Cradlepoint routers and edge devices. It supports downstream data rates up to 42.2 Mbps and upstream rates up to 5.76 Mbps using 256-QAM modulation. The module is designed for use with AER2200, AER1600, IBR1700 and IBR900 series platforms that support COR extensibility, and meets industry environmental and safety standards including UL/CUL, CB Scheme, EN60950-1 and MIL-STD-810G. The unit is finished in silver, measures approximately 70 × 13 mm and weighs 104 g.

Advantages

The MC400 delivers reliable cellular connectivity in a small form factor suitable for branch, mobile and IoT deployments. Its support for 256-QAM modulation and defined upstream and downstream throughput provides predictable IP performance for data and telemetry traffic. Native compatibility with specified Cradlepoint router series enables straightforward modular upgrades, including options for multi-modem configurations and LTE Advanced Pro capabilities when used in supported platforms. Compliance with recognized safety and environmental standards supports deployment in commercial and industrial environments.

How to use

Install the MC400 module into a compatible Cradlepoint router model that provides the COR modular slot and follow the router manufacturer’s hardware installation instructions. After physical installation, configure cellular settings through the router’s management interface to set APN, network selection and authentication parameters as required by the mobile network operator. Verify signal and registration status, then validate throughput and routing policies to incorporate the cellular interface into the device’s WAN or failover configuration.

Recommendations

For predictable performance, use the MC400 in routers that support its modular features and verify firmware compatibility before deployment. Place the host router where cellular signal strength is optimal and configure appropriate failover and security policies when using the modem for WAN connectivity.
