Inmarsat M2M

Inmarsat offer a broad range of M2M solutions

Machine-to-machine (M2M) communication refers to the exchange of data between devices without the need for human intervention. Satellite M2M communication enables devices to communicate with each other over a satellite network, which is particularly useful in remote or hard-to-reach areas where traditional cellular networks are unavailable or unreliable.

Inmarsat is a leading provider of global satellite communication services, including M2M communication. Inmarsat M2M modems are designed to provide reliable and efficient connectivity for M2M applications in remote and challenging environments.

One of the key benefits of using Inmarsat M2M modems is their global coverage. Inmarsat operates a network of geostationary satellites that provide coverage across the entire planet, including the poles and oceans. This means that M2M devices equipped with Inmarsat M2M modems can communicate with each other from anywhere in the world.

In addition to global coverage, Inmarsat M2M modems offer a range of features that make them ideal for M2M applications. For example, Inmarsat M2M modems are designed to be rugged and durable, able to withstand extreme temperatures, shock, and vibration. They also feature low power consumption, which is important for M2M devices that may operate in remote or off-grid locations.

Another important feature of Inmarsat M2M modems is their ability to provide two-way communication. This means that M2M devices equipped with Inmarsat M2M modems can not only send data, but also receive data and commands. This is particularly useful in applications such as remote monitoring and control, where devices need to be able to respond to changing conditions or instructions.

Overall, Inmarsat M2M modems are a reliable and efficient solution for satellite M2M communication in remote and challenging environments. With their global coverage, rugged design, low power consumption, and two-way communication capabilities, Inmarsat M2M modems are an ideal choice for a wide range of M2M applications, from asset tracking and remote monitoring to environmental sensing and disaster response.

  • Affordable: Low hardware costs with subscription-based price plans, no minimum connection fee and minimum billing increments.

Global, two-way IP data service designed for long-term machine-to-machine (M2M) management of fixed and mobile assets – no matter where they are.

If you want to monitor and control assets and infrastructure in remote locations globally, BGAN M2M is the service for you. Built upon our L-band satellite network BGAN M2M provides transparency and operational efficiency and with up to 99.9% uptime is trusted to work when other services fail.

BGAN M2M is ideal for applications with data volume requirements ranging from megabytes to gigabytes, such as real-time surveillance or high-volume metering and telemetry. It provides full IP data connectivity supported by remote terminal management, debugging and configuration options and using robust and lightweight hardware, BGAN M2M enables a wide range of M2M applications.

Service plans

BGAN-M2M offers a range of plans from low usage small scale deployments through bulk pooled data use for large-scale distributors.  Standard IP connectivity makes BGAN-M2M “plug and play” for many conventional M2M and IoT applications and devices. Pooled data plans reduce risk of unexpected costs if an anomaly occurs on a remote machine.


Our BGAN-M2M service is offered on a variety of rugged small terminals, targeting either fixed or mobile/vehicular deployments.  Terminals include standard remote management operations and provide a simple Ethernet interface for connecting to a machine/device or IoT gateway.  Available options on some models include hybrid LTE operation and wireless LAN.

Remote Management and M2M Gateway

Key Features

  • Centralized terminal status across large networks
  • Terminal bootstrap configuration based on profiles
  • Remote Terminal access in a highly secure way
  • Handling software upgrades with centralized UnitGate FTP repository
  • Tracking data usage to and from each single terminal
  • M2M transparent gateway – connect with M2M open source API’s
  • Manage M2M connected equipment as a store and forward
  • Centralized terminal overview with maps and lists
  • Smart connectivity across Inmarsat SMS, Direct IP, 3G/4G and Internet


Inmarsat GX Terminals

With the new Inmarsat GX terminals are UnitGate using direct assurance APIGEE access to statistics and terminal status – where more that 88 measurement points are constantly collected historically – allowing UnitGate to present and analyze data for most optimal outcome.

UnitGate also capture data files directly from the installed GX terminals using the established IP connectivity, allowing more terminal specific data grapping – UnitGate allow full control with initial terminal configuration across BGP, GreyTunnels, IP addresses, SVN’s, Prioritized port setting. On GX terminals do we collect location, altitude, temperature, jitter, latency, CIR up/down and lots of other valuable info.


Terminal Commands

All Inmarsat I4 terminals are coming with a long list of AT commands that are Inmarsat specific, Terminal specific and all the 3GPP commands that allow basically advanced remote handling of a terminal directly from UnitGate – our gateway allow easy and simple management with many terminals at the same time.

M2M Terminal Manager

Management with M2M units placed out in the field need a centralized management setup that in an easy way can manage connectivity, all remote terminals can based on user groups be displayed on a map where states can be displayed to get fast overview. UnitGate will allow automated management, be able to handle controlled software upgrades, be able to control the integrated input and output ports as well as show the status.


Terminal FTP Server

Loading of new software releases to terminals are using UnitGate FTP server to collect the new software version that for the different terminals are available for download – when UnitGate are requesting files from a given terminal like log files will they be transferred to the FTP server.

Remote Terminal Management

UnitGate are equipped with its own Inmarsat SMS gateway that allow SMS commands to be send to remote terminals to request establishment of a data session – IP address of UnitGate need to be added to satellite terminals in advance – SMS gateway can also be used to request location and similar from terminals supporting this command set.

After data session have been established will UnitGate act as a transparent gateway to a given terminal allowing telnet command access, or our GUI will allow management in a simple way by managing single changes or a new profile can be added.

It offer simple and efficient management with hundreds of remote installed terminals across vessels, airplanes and remote installed landbased M2M units like the new Cobham Explorer 540.


Smart Connect

Communicating with satellite units can become expensive if the communication and the connectivity isn’t managed in a smart way – UnitGate have optimized routing it will first try to connect across normal Internet directly to an alternative access to the equipped Ethernet port, then will it in case of Cobham Explorer 540 try across 3G/4G , then SMS/IP across the satellite network – all in a way so that the data traffic is as low as possible.


Terminal Profiles

New terminals can easily be remote configured using our bootstrap functionality – that will be loading and configuring a terminal just out of the box. This can be done directly using GUI or remote terminal access in a highly secure setup.

UnitGate allow configuration of profiles that contain specific setup of a given terminal – it is easy and simple to swap between different profiles allowing example simple and easy management for example expensive streaming services. Profiles can be for specific terminal types, for specific configuration setup and similar.


M2M Gateway

UnitGate are having the most common OpenSource M2M API interfaces added allowing it to act as a gateway between any M2M server and the connected units under satellite M2M units – UnitGate manage security – terminal IP mapping and can if needed be establishing needed data connectivity using SMS IP wakeup.
