AirLink® RX55
Rugged Industrial 4G LTE IoT Router
The Semtech AirLink RX55 is the world’s most power-efficient rugged industrial LTE-A Cat-7 router, delivering up to 300 Mbps downlink and 150 Mbps uplink in an ultra-low-power design ideal for solar, battery, or remote off-grid deployments. Built with an IP64-rated sealed aluminum enclosure, MIL-STD-810G durability, and wide -40°C to +70°C operation, it supports mission-critical applications in utilities, oil & gas, smart cities, transportation, and industrial IoT. Featuring Gigabit Ethernet, dual RS-232 serial, optional Wi-Fi 5, GNSS, CAN bus (select models), dual SIM redundancy, edge computing via Docker, robust security, and included AirLink Complete cloud management, the RX55 provides reliable, secure, and cost-effective LTE connectivity for harsh and energy-constrained environments.
World’s Most Power-Efficient Rugged 4G LTE-A Router
The Semtech AirLink RX55 is the world’s most power-efficient rugged industrial 4G LTE-A (Cat-7) IoT router, optimized for extreme and remote environments with ultra-low power consumption. It delivers reliable connectivity (up to 300 Mbps downlink / 150 Mbps uplink) for mission-critical applications in utilities, oil & gas, smart infrastructure, transportation, energy, and industrial IoT — including solar/battery-powered deployments where power efficiency is essential.
This compact router features a sealed aluminum IP64-rated enclosure, MIL-STD-810G compliance, wide temperature range (-40°C to +70°C for base model), and robust power protection. Interfaces include 1x Gigabit Ethernet, dual RS-232 serial (base model), optional dual 1×1 Wi-Fi 5, 30-channel GNSS, CAN bus support (select models), 1 GPIO, USB 2.0, and dual SIM slots for redundancy. It supports advanced networking (IPv4/IPv6, NAT, QoS, policy routing), security (stateful firewall, IPsec VPN), and edge computing (Docker containers on Wi-Fi Plus model for early adopters).
AirLink Complete (1-year included) provides cloud management via AirLink Management Service (ALMS), 24/7 support, extended warranty (up to 5 years), and critical firmware updates. Optional AirLink Premium adds advanced reporting and advance replacement; hybrid/on-premise options available with licenses.
- Ultra-Low Power Consumption Lowest idle power in its class (~900 mW LTE idle, ~53 mW standby) — enables long-term solar, battery, or off-grid operation, minimizing energy costs and infrastructure needs in remote locations.
- High-Performance LTE-A Connectivity Cat-7 LTE-A with up to 300 Mbps downlink / 150 Mbps uplink — provides fast, reliable broadband for demanding IoT, video, and enterprise applications with 3G fallback for coverage.
- Rugged Industrial Design IP64-rated sealed aluminum enclosure, MIL-STD-810G compliant, wide -40°C to +70°C operating range — withstands extreme shock, vibration, dust, moisture, and temperature for harsh environments.
- Flexible Interfaces 1x Gigabit Ethernet, single/dual RS-232 serial, optional dual 1×1 Wi-Fi 5 (433 Mbps theoretical, dual-band), 30-channel GNSS, 1 GPIO, USB 2.0, dual SIM slots — connects diverse legacy/modern devices, supports redundancy/failover and precise tracking.
- Edge Computing Ready Supports containerized workloads (Wi-Fi Plus model for early adopters) — enables local data processing, filtering, and custom IoT logic to reduce latency and cloud dependency.
- Advanced Security & Networking Stateful firewall, IPsec VPN (up to 10 tunnels, AES-256, FIPS 140-2 compliant), WPA2/WPA3, remote authentication, QoS, policy routing, IPv4/IPv6 — ensures secure, optimized traffic for mission-critical use.
- Remote Cloud Management Included AirLink Complete subscription (1-year) with AirLink Management Service (ALMS) for remote monitoring, configuration, firmware updates, 24/7 support, and warranty extension up to 5 years — simplifies operations across distributed assets.
- Certifications & Reliability FirstNet Trusted (select models), carrier approvals, hazardous location (Class 1 Div 2, IECEx/ATEX planned), vehicle (E-Mark, SAE J1455), rail (EN50155/EN45545) — trusted for utilities, oil & gas, public safety, smart cities, and transportation.
- Cost-Effective for Remote Assets Low power + rugged design lowers total cost of ownership for utilities, smart grid, oil & gas, transportation, industrial IoT, and protected remote monitoring applications.
