What Is IoT? How the Internet of Things Works, the Technology Redefining Global Connectivity

The communication between devices and the data they generate can be transformed into useful information that makes our lives easier. This is the principle behind the Internet of Things (IoT), a technology designed to help us make better decisions and optimize resources.

Definition and How IoT Works

IoT, or the Internet of Things, refers to the entire network of physical devices that are interconnected and capable of transmitting all kinds of information without human intervention. For example, technological advancements now allow ovens, washing machines, or heaters to be controlled from a smartphone. However, IoT aims to go far beyond that.

Objects within the IoT network are connected to each other. This process, known as D2D (device‑to‑device), is made possible because devices communicate through wired networks, Wi‑Fi, or Bluetooth. Once connected, the devices’ sensors and embedded chips begin to collect and generate activity data, which is then stored, processed, and analyzed on a centralized platform. Finally, the data triggers an automatic action or sends an alert for a person to make a decision.

Although this technology may sound futuristic, the reality is that many households already use it. Who hasn’t heard of Alexa? Amazon’s smart system is connected to a network that can perform actions such as opening blinds, locking doors, or even doing the shopping.

What Types of Devices and Networks Are Involved?

Today, satellite IoT makes it possible to connect assets and sensors far beyond the reach of traditional terrestrial networks. Thanks to technologies like those from FOSSA, it is possible to monitor and control equipment, fleets, and processes in remote areas without relying on mobile or Wi‑Fi coverage.

Logistics and Transportation

Satellite‑connected IoT sensors make it possible to actively track the location, temperature, humidity, door openings, and overall condition of containers, trailers, and goods.
These devices help to:

  • Prevent theft or unauthorized deviations.
  • Monitorizar mercMonitor sensitive goods (pharmaceuticals, perishables, chemicals, etc.). ancías sensibles (farmacéuticas, perecederas, químicas…).
  • Optimize routes and delivery times.
  • Comply with traceability regulations.

The satellite network ensures that assets continue reporting even across maritime routes, deserts, or areas without coverage.

Oil & Gas

In critical and remote sectors such as Oil & Gas, satellite‑enabled IoT sensors monitor environmental variables and infrastructure performance.
Key applications include:

  • Measuring pressure, levels, and flow rates in pipelines.
  • Early detection of leaks or anomalies.
  • Supervising remote tanks and stations.
  • Monitoring equipment conditions for predictive maintenance.

These devices operate in extreme locations where no terrestrial networks exist and reliability is essential.

Smart Agriculture

Farmers install soil, climate, and irrigation sensors that transmit data via satellite networks to avoid coverage gaps.
This enables:

  • Optimize water usage through soil‑moisture sensors.
  • Control soil fertility, nutrients, and overall soil health.
  • Monitor livestock and machinery across large farms.
  • Manage crops more precisely and profitably.

The goal: maximize yield, reduce costs, and improve sustainability.

Industrial Infrastructure and Machinery

  • Anticipate failures before they affect production.
  • Monitor energy consumption and performance.
  • Automate processes in isolated facilities.
  • Manage fleets of heavy machinery in mining or construction.

Satellite connectivity ensures continuous data flow even in temporary worksites, open‑pit mines, or rural areas without mobile coverage.

Connected Cities and Territories

Satellite IoT complements urban infrastructure by supporting:

  • Sensors for wildfire detection and environmental risk monitoring.
  • Water monitoring and air‑quality control in rural areas.
  • Management of public lighting or critical infrastructure outside city limits.

Satellite connectivity is essential for linking territories where deploying towers or fiber is not feasible, and for preventing situations like the major blackout in Spain, where 60% of the power supply was lost.

Basic IoT Data Cycle: Sensing, Communication, Analysis, and Action

The basic data cycle in the Internet of Things (IoT) consists of four stages:

  • Sensor (data capture): At the beginning of the cycle, sensors or devices in the IoT network collect information—temperature, movement, humidity, etc. This data becomes the foundation for the following stages of the process.
  • Communication (data transmission): Once collected, the information from all devices is transferred to a centralized platform. This is made possible through communication channels such as Wi‑Fi, Bluetooth, wired networks…
  • Analysis (data processing): The goal of this analysis stage is to turn data into practical, actionable information—detecting patterns, anomalies, and determining what actions are needed. There are two main methods for processing and analyzing data: in the cloud or directly on the device.
  • Action (response or automation): Based on the analysis results, the user decides how to act and how the data will be processed or utilized.

Advantages of IoT in Companies and Everyday Life

The implementation of IoT has brought significant operational and competitive advantages that simplify daily life for both individuals and businesses:

  • Automation and efficiency: Automation minimizes human error since people no longer intervene in executing routine actions. This improves productivity and streamlines tasks.
  • Data‑driven decision‑making: Sensors can collect information from any activity, meaning there is virtually no situation that cannot be translated into data. As a result, every decision can be based on pattern analysis, accelerating the decision‑making process.
  • Comfort and personalization: At home, devices adapt to residents’ routines. IoT provides full control over lighting schedules, indoor humidity, temperature, and security systems according to user preferences.
  • Sustainability: Implementing IoT in industrial and agricultural sectors enables greater control and more efficient use of resources. In fact, it is essential for optimizing the energy consumption of natural resources, helping reduce environmental impact.

Cost Savings and Operational Efficiency

The control and optimization of resources enabled by the Internet of Things also have a positive impact on final production costs and overall process efficiency. By turning any action into data, the system can detect failures—or early signs of them—with far greater accuracy. Trend analysis allows human teams to anticipate issues even before they become costly problems.

For example, installing IoT systems in industrial environments enables predictive maintenance, extending the operational lifetime of machinery.

The combination of IoT technology and satellite communication is paving the way toward truly global connectivity, where every sensor, device, or machine can share data. At FOSSA Systems, we work to make that future a reality—connecting industries, people, and environments in smarter, more efficient ways.
