AirLink® LX40
Ultra-Compact 4G Router
The Semtech AirLink LX40 is an ultra-compact 4G LTE router designed for simple, out-of-the-box deployment in fixed, protected environments. It provides reliable LTE connectivity with optional Wi-Fi, making it ideal for security systems, digital signage, IoT devices, and enterprise applications where space is limited and quick setup is essential.
This router supports same-day operations with easy installation, connects a wide variety of devices (from video to low-power IoT), and offers a compact form factor to expand deployment possibilities. Built on Semtech’s proven cellular expertise, it ensures secure, efficient performance for distributed locations.
The Semtech AirLink LX40 is the industry’s most compact LTE router, delivering secure, managed connectivity for IoT, M2M, and enterprise applications in indoor or protected outdoor environments. It provides out-of-the-box LTE networking (up to 150 Mbps download / 50 Mbps upload) with optional LTE-M/NB-IoT variants for low-bandwidth global deployments, making it ideal for IP cameras, security systems, point-of-sale terminals, smart lockers, remote data logging, and sensing equipment.
This ultra-compact router features Power-over-Ethernet (PoE PD) support for simplified low-power installations, intelligent edge processing via the ALEOS Application Framework (AAF) to pre-process or filter IoT data at the source, and an optional Wi-Fi version that serves as a local hotspot or connects to existing Wi-Fi infrastructure. With robust industrial-grade design, low power consumption, and FirstNet Trusted certification, the LX40 ensures reliable performance in diverse fixed and protected locations.
Remote, secure management is handled through AirLink Complete (included), offering cloud-based oversight, 24/7 support, and firmware updates, with optional on-premise alternatives. The LX40 combines flexibility, security, and ease of deployment in the smallest form factor of its class, empowering businesses to connect and manage critical assets efficiently.
- Industry’s Most Compact Form Factor Extremely small size allows deployment in tight spaces, kiosks, cabinets, and embedded applications where larger routers won’t fit.
- Ultra-Low Power Consumption Minimal idle and standby power draw makes it perfect for battery-powered, solar, or remote low-power IoT deployments — reduces infrastructure and energy costs.
- Reliable LTE Connectivity LTE Cat-4 (up to 150 Mbps DL / 50 Mbps UL) or optional LTE-M/NB-IoT variants provide excellent global coverage, deep in-building penetration, and long-range performance for low-bandwidth IoT.
- Optional Dual-Band Wi-Fi 5 Acts as a local hotspot or connects to existing Wi-Fi infrastructure — adds flexibility for connecting nearby devices like tablets, sensors, or cameras.
- Power-over-Ethernet (PoE PD) Support Simplifies installation in fixed locations by powering the device over Ethernet — eliminates separate power cabling and reduces setup costs.
- Intelligent Edge Processing ALEOS Application Framework (AAF) enables custom data processing, filtering, and IoT logic at the edge — reduces cloud dependency and latency.
- Secure & Managed Out-of-the-Box Built-in defense-in-depth security plus AirLink Complete (included) delivers remote cloud management, 24/7 support, firmware updates, and warranty extension — simplifies operations across distributed sites.
- FirstNet Trusted & Carrier-Approved Certified for public safety use (select models) and approved by major carriers — trusted for mission-critical and enterprise applications.
- Protected Environment Durability Industrial-grade design with wide temperature range and robust power protection — reliable performance in indoor or protected outdoor locations.
