Key Takeaways
- Semtech has launched two new 5G RedCap models, the AirLink RX400 and EX400, targeting industrial IoT use cases.
- Both routers operate on 5G Standalone architecture, are low power, and provide dual-mode support for LTE, making them ideal for off-grid environments.
- The RX400 is designed for outdoor use with rugged specifications, while the EX400 is suited for indoor commercial applications.
New 5G Solutions for Industrial IoT
Semtech has introduced two innovative models in its AirLink router line: the AirLink RX400 and EX400, specifically designed to meet the demands of industrial and commercial operators. These 5G RedCap routers target various industrial Internet of Things (IoT) applications, particularly in areas where 4G LTE technology is still prevalent.
Many existing field assets rely heavily on 4G LTE connectivity, and often operate in remote locations with limited power and minimal on-site support. Semtech’s new models are purpose-built to address these challenges, especially as typical 5G routers can exceed the power budgets suitable for off-grid or embedded environments. The company positions its 5G RedCap models, as defined in 3GPP Release 17, as effective solutions for such use cases.
The RX400 and EX400 routers feature a 5G Standalone architecture, supporting both 5G RedCap and LTE Cat 4, allowing for immediate deployment, particularly where RedCap coverage remains sporadic. With equipment lifespans extending into years, the dual-modality support could decrease the frequency of necessary device refreshes.
An important highlight is that both models draw less than one watt when idle. This makes them particularly attractive for environments struggling to justify a switch to 5G due to power constraints. For example, remote infrastructure monitoring applications requiring off-grid supervisory, data acquisition, or metering backhaul could benefit from these energy-efficient routers.
The low idle power consumption also positions the RX400 and EX400 well for commercial IoT deployments across various sectors, including retail, manufacturing, and agriculture. Their compact design accommodates locations with limited power sources, and they could support temporary setups that leverage solar or battery power while utilizing 5G.
The two models do have distinct design specifications and intended deployment environments. The AirLink RX400 is ruggedized for outdoor and critical infrastructure, boasting an IP64 rating and compliance with MIL STD 810H standards, making it resistant to dust, moisture, vibration, and temperature extremes. Semtech claims it to be the most power-efficient 5G RedCap router available. It supports several private LTE and 5G bands, including Anterix Band 106 in the 900 MHz spectrum outlined in 3GPP Release 18. Hardware options include single or dual serial ports, a single gigabit Ethernet port, and optional Wi-Fi 6 capabilities.
Conversely, the AirLink EX400 is designed for less demanding commercial and light industrial environments. It is more suitable for indoor use or ‘sheltered’ deployments, featuring two gigabit Ethernet ports and optional Wi-Fi 6, but lacks the rugged specifications of the RX400.
For both models, Semtech offers a 2-by-2 MIMO antenna configuration, which is expected to meet the throughput and latency requirements for typical IoT workloads. While specific peak data rates are not disclosed, this should not be a primary concern for most users.
The routers come with one year of AirLink Complete support, a hardware warranty, and access to technical assistance. Remote device management is enabled through the cloud-based AirLink Management interface, allowing operators to monitor and configure their fleet easily. Additional management options are available through Semtech’s AirLink Manager and AirLink Mobility Manager, which can be hosted as a service or deployed on-premises.
The RX400 and EX400 routers are now available through authorized Semtech AirLink channel partners.
