Самый революционный из них — Интернет вещей. (Интернет вещей). Его сети определяют Интернет вещей, но что такое сеть Интернета вещей, и почему это так важно? В этом блоге, вы узнаете, что такое сети IoT, the various categories of uses, and the considerations when choosing an IoT network.
What Is an IoT Network?
An IoT network is the very central to the Internet of Things and is the connectivity of IoT-устройства, датчики, программное обеспечение, and systems. But what does an IoT network mean? In other words, it is a network that allows IoT devices to interface with the Internet or other devices for the exchange of information. This connectivity is the most crucial in IoT systems since it offers the integration, функциональность, and delivery of information at the right time.
IoT networks are created with the assistance of various communication technologies like wireless fidelity (Wi-Fi), Bluetooth, Зигби, and cellular technology. These networks are designed to fulfill the specifications of IoT devices, например, малая мощность, long range and many to many topologies.
How Does an IoT Network Function?
To understand the functionality of IoT networks, it is necessary to break down the process into four key components:
IoT Sensors – Data Collection
Sensors are the core of any IoT network. These sensors acquire information from the physical context, например, температура, влажность, движение, or light. The information collected by these sensors is the basis of IoT networks and contains the necessary information for further analysis and decision-making.
IoT Connectivity – Data Transmission
Once the data has been collected, it has to be taken to a central place where it will be analyzed. This transmission is made possible by connectivity, which is through the use of IoT connectivity as a mode of connectivity. Wi-Fi, Bluetooth, and cellular networks are some of the technologies used to transfer data in an IoT network. This connectivity is essential for the proper functioning of IoT devices and their capacity to communicate with other devices and networks.
IoT Processing – Data Processing
Data that has been transmitted must then undergo analysis to be able to derive useful information from it. IoT computation refers to the analysis of the data that is gathered and the subsequent decision-making process that is done through the use of software and algorithms. This step is important in converting the raw data into useful information for automating the processes and improving the decisions that are made.
IoT Interface – Data Sending
Last of all, the data is passed to the user interfaces or other systems for further processing. Этот could mean sending notifications, invoking responses, or even presenting data on a screen. The IoT interface is the link between the data and the users, such that they can get to interact with the IoT system and make the right decisions.
Why are IoT Networks Important?
The IoT networks are essential in the present day’s technology for the following reasons. First, they enable the establishment of links between devices and systems that may optimize workflow, productivity and decision-making processes. Например, in smart cities, IoT networks control traffic lights, датчики, and cameras to enhance traffic flow and minimize congestion.
Second, IoT networks allow for real-time monitoring and control, which implies that changes can be made and the processes can be optimized. In healthcare, например, IoT networks help in tracking patient’s health with the aim of acquiring their health data periodically.
Last but not least, IoT networks encourage innovation through the creation of new products and services that are based on the use of connected devices. From home automation to industrial uses, IoT networks are the foundations of future technologies.
4 Categories of IoT Networks
IoT is the connection of millions of devices, and all these millions of devices use different network types to perform optimally. Например, если the aim of the application is to monitor crops and livestock, например, then the type of network that is used is critical. Here’s a look at the four main categories of IoT networks: A brief description of the four primary categories of IoT networks is provided below.
Cellular Networks (4г, 5г)
Due to the high coverage and data rate, the cellular networks that were originally developed for mobile communications have become an essential part of IoT. Key features include:
- High Bandwidth: Cellular networks have high throughput and are ideal for use in applications such as live video surveillance and self-driving cars.

- Зигби: Zigbee is a low-power solution used in home automation and industries; Zigbee also supports a mesh network that allows the devices to communicate as well as act as a relay to other devices.
Mesh Protocols
Mesh networks are becoming increasingly popular because of their distributed topology, which improves dependability and scalability. They feature:
- Decentralized Communication: Every device (node) can forward data to other devices and can recover if one of the nodes is down.
- Масштабируемость: The network is more robust when more devices are connected, and it is appropriate for applications such as smart lighting systems and large industrial complexes.
- Надежность: Mesh networks are not particularly sensitive to single points of failure, which is a key consideration for applications such as smart buildings and industrial automation.
IoT Network Samples: Devices and Usage Scenarios
To better understand the applications of IoT networks, let’s explore some real-world examples across different environments. Now let us look at some of the examples of IoT networks in different environments to get a clearer picture of their use in everyday life:
Farm
In the field of agriculture, IoT networks are very useful in precision farming. Various devices installed in the farm are used to monitor the moisture content, temperature and health of crops in the farm. This information is relayed to a central system where it is processed to enhance irrigation, fertilization and pest control, hence enhancing crop yields and reducing wastage of resources.
Tunnel
In tunnel monitoring, IoT networks offer safety and management of transport systems in tunnels. The condition of the air, температура, and structural health of the building are detected and transmitted in real time to the control centers. Этот makes it possible to address any concerns as and when they arise, например, inadequate ventilation or structural failure that may compromise the lives of the passengers and workers.
Больница
Hospitals use IoT networks to improve the quality of services they offer and to optimize their functioning. Smart wearables, например, health monitoring devices and smart beds, gather data on the patient’s vital signs and movements respectively, and this data is analyzed to identify any signs of health complications. This real-time monitoring helps in early intervention, and hence, the patients get better results while the burden on the health care staff is also reduced.
