GX450 Benefits

Vehicle Area Networking: Consolidate Connections

The GX450 is available in four configurations to provide vehicle-area connectivity tailored for each application environment. The base model provides connectivity for wired Ethernet, Serial and USB devices in the vehicle; an Ethernet option provides additional Ethernet ports. With the Wi-Fi option, the GX450 also includes an 802.11 b/g/n mobile access point for wireless devices and a Wi-Fi client for depot/station communications. An I/O option provides 4 digital input/outputs and 4 analog inputs to monitor external system events and sensor inputs. Consolidating all devices according to your requirements at the vehicle reduces the number of modems, antennas and subscriptions otherwise needed.

Secure Mobile Communications

The GX450 is loaded with features to secure your critical data. With up to 5 concurrent VPN sessions, you can ensure secure communications to multiple back-end systems. Remote authentication management allows you to use enterprise grade systems to manage access to devices in the field. Finally, port filtering and trusted IP protect the devices connected to your GX450 from unwanted access.

Rugged Design for Demanding Vehicle Applications

The GX450 is designed from the ground up to withstand the harsh environmental conditions of vehicle use. The die cast aluminum housing is sealed to meet IP64 levels of resistance to dust and water ingress. The product is tested to meet and exceed the MIL-STD-810G specification for shock, vibration, temperature and humidity. Immunity to harsh electrical transients is covered to meet international vehicle use standards.

Report and Alert: Don't just Communicate

As a fleet manager, you need more than just communications. You need to monitor the safety of your mobile workforce and the state of your vehicles. For example, you need to know if a worker has set off a man-down alert or if a police car has engaged the lights and siren. For this, you need the AirLink integrated events engine. This powerful tool allows you to develop custom event triggers and create tailored reports that communicate what’s happening in the vehicle to third party server platforms - all without any programming. An optional OBD-II Telemetry Accessory Kit allows you to collect engine diagnostic and performance data to monitor the health of your vehicles. Best of all, through the Sierra Wireless Solution Exchange, you have access to a catalogue of world class solution partners that have already integrated this functionality into their AVL and mobile workforce solutions.

Network Management

Managing a fleet of mobile gateways is a demanding task.

You need to maintain multiple device configurations, update device software, and remotely diagnose reported issues. 

In the Cloud: 

AirLink® Management Service 

AirLink Management Service (ALMS) enables over-the-air registration, configuration and software updates for the complete portfolio of AirLink gateways and routers. (For MG90/oMG, please see AMM below.)

Available as a cloud-service, ALMS provides a dashboard view of the entire deployment, including signal strength, network technology and location. Custom alerts can be set-up to monitor and report critical events, which help you in increasing efficiency and preventing downtime. 

In the Enterprise: 

AirLink® Mobility Manager

AirLink® Mobility Manager (AMM) enables simplified, remote and real-time mass configuration, control and troubleshooting of all routers, connected mobile assets and mission critical applications.

Available in the enterprise datacenter, AMM displays a dashboard with an up-to-date view of the entire fleet, and delivers a continuous stream of rich, real-time network data, allowing users to observe, track and examine the behaviour of hundreds of devices, networks, and connected parameters as they occur.

Mobile Multi-Network Security

AirLink® Connection Manager (ACM)

Secure IP Mobility, Sub-Second Switching

The AirLink® Connection Manager (ACM) is a mobile-optimized VPN server that securely extends the enterprise network to the vehicle. Designed to work with AirLink® gateways and routers, the ACM consolidates security onto a single platform for all connected devices and applications in the vehicle area network.

Embedded Intelligence

Embedded Intelligence


ALEOS software is the power behind AirLink gateways that enables them to connect out-of-the-box. Its rich set of configurable parameters simplifies and decreases your time to deployment by:

  • Providing two-way communications between connected machines and AirLink gateways over Ethernet, serial, digital and analog I/O, USB, and Wi-Fi
  • Collecting machine information through standard protocols
  • Communicating securely over cellular networks to back-end IT systems and cloud services.

With automatic network fallback, ALEOS is built to get connected and stay connected. Together with AirLink Management Service, ALEOS enables you to set up your own security and networking settings (i.e. VPN tunneling, port forwarding, and routing); activate GPS location tracking and generate reports without any programming.

ALEOS Application Framework

Get the business data you need from field operations into your back-end systems. ALEOS Application Framework (AAF) provides a simple scripting interface that requires no deep embedded or wireless expertise to gather vital machine data. Integrated with AirVantage® IoT Platform, you can quickly incorporate field data to build powerful IoT applications using web-friendly APIs.
