The Semtech AirLink EX400 is a right-sized 5G RedCap router built for commercial IoT applications that demand reliable connectivity, long-term network longevity, and ultra-low power consumption. Supporting both 5G RedCap and LTE Cat 4, the EX400 enables organisations to deploy confidently today while remaining future-ready as 5G RedCap networks continue to expand.

Designed for indoor or protected outdoor environments, the AirLink EX400 features a compact, semi-rugged IP30-rated form factor with dual Gigabit Ethernet, optional WiFi 6, and USB-C connectivity. Its exceptionally low idle and standby power consumption makes it ideal for solar-powered and battery-operated installations, helping to extend 5G connectivity to locations where traditional routers may be impractical.

Powered by AirLink OS, the EX400 supports flexible device management through the cloud-based AirLink Management Service with AirLink Complete, as well as optional on-premises platforms including AirLink Manager and AirLink Mobility Manager. Sharing the same mounting pattern as the AirLink RV series, the EX400 allows straightforward upgrades to 5G RedCap while maintaining consistent installation workflows.

The AirLink EX400 is well suited to distributed commercial IoT use cases such as digital signage, smart machines, manufacturing, EV charging infrastructure, and smart agriculture.
