Semtech Corporation, a leading provider of high-performance semiconductor, Internet of Things (IoT), and cloud connectivity solutions, announced two new AirLink 5G RedCap routers to address a critical gap in industrial and commercial IoT: the need for future-proof and energy-efficient 5G connectivity scaled to real-world IoT application needs.
The new AirLink RX400 and AirLink EX400 routers deliver 5G RedCap performance while consuming less than 1 watt of power when idle, enabling deployments in remote, off-grid locations previously served by existing LTE networks or traditional 5G solutions. Both routers deliver the throughput and low latency necessary for IoT applications and have a 2x2 Multiple Input Multiple Output (MIMO) antenna configuration to simplify integration into existing and new deployments.
Based on 3GPP Release 17 and 5G Standalone (SA) architecture, 5G RedCap technology delivers enhanced network performance and future-proof longevity as carriers continue to modernize their infrastructure. The RX400 and EX400 support 5G RedCap but also LTE Cat-4 for flexible connectivity and immediate deployments.
Key Applications and Use Cases
The sub-1W power efficiency of both routers is intended to enable new 5G deployment scenarios:
Remote Infrastructure Monitoring: Off-grid supervisory control and data acquisition (SCADA) or advanced metering infrastructure (AMI) backhaul in energy and utilities.
Critical Infrastructure Monitoring: Remote system monitoring in oil and gas.
Distributed Commercial IoT: Retail, manufacturing, and agricultural operations.
Temporary Installations: Mobile deployments where grid power is unavailable or cost-prohibitive.
AirLink RX400: Rugged 5G RedCap Router for Outdoor Environments
The AirLink RX400 5G RedCap router has a rugged IP64 and MIL-STD-810H design for challenging outdoor environments and applications requiring maximum reliability. The combination of rugged design and low power consumption optimizes it for critical infrastructure applications where grid power is unavailable, enabling solar-powered operation in remote locations.
The router supports global private LTE and 5G bands, including Anterix Band 106 (900 MHz spectrum standardized under 3GPP Release 18), delivering versatility and future-proofing that is essential for mission-critical deployments across energy, utilities, and industrial sectors. The router also features a single/dual serial port, a single Gigabit Ethernet port, edge computing capabilities, and optional Wi-Fi 6.
AirLink EX400: Semi-Rugged Design for Commercial IoT
The AirLink EX400 features a semi-rugged design for use in IoT applications in retail, manufacturing, and agricultural operations. The router features dual Gigabit Ethernet ports, edge computing capabilities, and optional Wi-Fi 6.
Network Management
The RX400 and EX400 include one year of AirLink Complete with hardware warranty, 24/7 support, and remote management through the cloud-based AirLink Management Service (ALMS) platform. This allows organizations to securely monitor, manage, and automatically update router deployments at scale.
Semtech is also expanding management options for its AirLink OS-based routers—including the AirLink RX400 and AirLink EX400—through optional management via AirLink Manager (AM) and AirLink Mobility Manager (AMM) platforms. These management solutions can be deployed hosted or on-premise.
