IoT: Advanced technology in the 4.0 era revolution

Leading the technology race in the current 4.0 era is IoT or Internet of Things. This definition is gradually becoming familiar in life and business, it is widely applied and its benefits have been clearly demonstrated. In the article below, the author will provide a lot of interesting information!

1/ What is IoT?

IoT gadgets, also referred to as “smart devices,” range from sophisticated industrial equipment and transportation systems to smart watches and RFID-enabled apparel. IoT-based “smart cities” as a whole are even being imagined by technologists.

These smart gadgets may speak with other internet-enabled devices as well as with one another thanks to IoT. Build a massive network of networked devices that can share data and carry out a range of functions on their own, similar to cell phones and gateways.

IoT has many potential uses, and its effects are already being seen in many different areas, including manufacturing, transportation, healthcare, and agriculture. The Internet of Things (IoT) is expected to become more significant in influencing our environment as the number of devices linked to the internet rises. It is also changing the way we live, work and interact with each other.

IoT devices are utilized in business settings to monitor a wide range of characteristics, including machine performance, energy usage, temperature, humidity, and air quality. Real-time analysis of this data may reveal patterns, trends, and anomalies that can help companies increase profitability and streamline operations.

2/ IoT structure

To understand the capabilities of the IoT architecture, it is important to be aware of its key layers that enable successful implementation. These key factors are:

  • Perception/Sensing Layer
  • Connectivity/Network Layer
  • Data Processing Layer
  • User Interface/Application Layer

We will now explore each element individually to understand how they integrate with each other in creating a proficient IoT system.

  • Perception/Sensing Layer

The IoT system’s foundation is the sensor layer. It is made up of actuators and sensors that gather and analyze data from outside sources. In order to provide raw data for analytics at higher architectural levels, this layer is crucial in gathering data from the actual world.

For instance, the placement of sensors on a car assembly line may be used to assess quality control by means of robot operations, with the output being sent to further layers for further processing.

These systems’ capacity to get the essential information required to engage with reality will be compromised in the absence of this level in any Internet of Things network, restricting them to externalities and diminishing their potential.

  • Connectivity/Network Layer

For digital data to flow between all the elements of the Internet of Things architecture, it must pass via the network layer, often referred to as the transport layer or device layer. It makes use of technologies like AMQP, MQTT, and HTTP to make communication between devices and applications easier. Furthermore, when paired with capabilities like private 5G mobile networks that provide complete control over information transfer, this same degree of connectedness may create a safe environment.

HTTP, MQTT, and AMQP are the basis for all data sharing on the Web. Because these are client-server protocols, requests are made by the recipient, usually a Web browser.

An internet gateway that permits communication outside the local system, an internal network gateway that serves as both an internet gateway and an access point on these local systems, a network gateway that bridges multiple devices together simultaneously, and lastly a Data Acquisition System (DAS) that enables the collection of sensor readings throughout the system make up this system.

  • Data Processing Layer

The data is processed and analyzed at the data processing layer to support decision-making and operational efficiency for enterprises. Using machine learning techniques, it can interpret unprocessed data from the Internet of Things system and save pertinent facts for automated decision-making.

This stage also includes edge analytics and AI approaches, which assist to filter out device data that is useless or irrelevant prior to analytics. When these measures are successfully put into practice, the quality of the insights gained from the raw data gathered is improved, leading to effective action on what is required. This improves real-world outcomes. This is a crucial step toward having IoT devices use the data they gather to create better efficient outputs.

  • User Interface/Application Layer

In Internet of Things design, the user/application interface layer provides a crucial framework that enables users to communicate with the system and access certain services. This enables consumers to utilize their devices whenever it is most convenient for them, whether that means touching a mobile app or using a computer’s core panel.

When someone utilizes an app made especially for smart homes, this may be an example. The push-button feature of the app allows them to easily turn on the coffee machine. To put it briefly, these apps make sure users of IOT systems have a seamless experience so they can get the most out of them.

3/ Advantages and disadvantages of IoT

  • Capability to oversee and guarantee efficient operations
  • Increase process automation to cut down on mistakes, malfunctions, and the need for human involvement.
  • Reduce time and expenses because of increased productivity and cross-device data exchange.
  • Boost personnel and general productivity.
  • Facilitate better decision-making in business
  • Gather and combine data sets from many sources to facilitate analysis, business modeling, and innovation.



  • An increasing number of linked gadgets gives hackers more opportunities to breach networks and pilfer private data.
  • When mistakes happen in the system, connected gadgets may harm one another.
  • More IoT devices translate into more data being created, which increases the need for data management—possibly needless.
  • The absence of a standard for Internet of Things devices raises the possibility of incompatibilities between products made by various vendors.

4/ Why is the IoT important?

IoT is critical in the future market since everything now relies on the internet and smart devices. The Internet links devices to gather and transfer data over a network, making it a critical element in the near future.

Organizations primarily target this network globally, guaranteeing that their products are built utilizing IoT architecture alone. Marketing organizations must also adapt to new global market trends, since numerous corporations have gained significantly from implementing IoT into their operations.

This helps the organization strengthen its human resource capabilities and commercial performance. IoT is quickly expanding and becoming more popular. According to current market trends, it is the leading force in digital marketing and other industries.

5/ Conclusion

In summary, through the article, our author wants to emphasize that IoT brings countless benefits from daily household use to surveillance, industrial manufacturing and even entire smart city applications.  If users and businesses know how to apply and develop the advantages of IoT, they will have more chances of success in their fields.
