5G RedCap adoption is accelerating. The technology delivers the right combination of attributes for industrial applications: 5G network longevity, power efficiency, and 5G performance that matches real-world industrial requirements - without the cost premium of traditional 5G. As LTE networks phase out, 5G RedCap will provide organizations with a deployment path that makes both technical and economic sense.
The Airlink RX400 router delivers 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 expensive, high-power traditional 5G solutions. The router delivers the throughput and low latency necessary for IoT applications and has a 2x2 Multiple Input Multiple Output (MIMO) antenna configuration - to simplify integration into existing and new deployments. 5G RedCap technology delivers enhanced network performance and future-proof longevity as carriers continue to modernize their infrastructure. The RX400 supports 5G RedCap but also LTE Cat-4 for flexible connectivity and immediate deployments.
The AirLink RX400 is one of the industry’s most power efficient 5G RedCap routers with 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 the versatility and future-proofing that is essential for mission-critical deployments across energy, utilities and industrial sectors. The RX400 also features a single/dual serial port, a single Gigabit Ethernet port, edge computing capabilities, and optional Wi-Fi 6.
The RX400 includes 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 without overwhelming IT support teams.
