The term “wireless” refers to technologies and methods that enable the transmission of data and voice through the air without physical cables or wires.

This type of communication uses electromagnetic waves such as radio frequencies, infrared, and satellite communication to connect devices and transmit information over long distances.

The term “wireless” therefore refers to a technology that enables the contactless and automatic identification and transfer of information between a marked object or living being using a reader, camera, or scanner. It is important that the object be marked or carry biometric recognition itself.

The concept of wireless technology dates back to the 19th century.

Pioneers and scientists such as Heinrich Hertz proved the existence of electromagnetic waves. Guglielmo Marconi succeeded in transmitting signals wirelessly over long distances.

Over the years, wireless radio technology has evolved and taken various forms, including mobile phones, Wi-Fi, Bluetooth and satellite communication. They are designed for different purposes and use different frequencies and transmission methods.

The term “Internet of Things” (IoT) is initially just a generic term for a digital infrastructure. In the IoT, physical and virtual objects can actively network and communicate with each other. The IoT is therefore about the active networking of people, things, machines, systems, devices, or even events. This is usually done with the intention of establishing a logical and semantic connection.

The information in the IoT can relate to the existence, location, speed, status, quantity, shape, and direction of an object.

The data can relate to the past, present, and future. The number of objects/actors involved and the amount of data exchanged is constantly increasing. Whether this number can be infinite is still under discussion.

The combination of “wireless” and “IoT” means automation, transparency, networking, connectivity, and speed. Identified objects communicate with each other or with systems and provide information about their status.

Processes are triggered based on this information. This includes maintenance processes, identification processes, logistics processes, production processes, security processes, and much more. Overall, this results in speed and transparency, as well as a forward-looking approach to decision-making. However, there is also a challenge: Security on the Internet!

The number of cybersecurity service providers for the IIoT is growing due to the very high demand. According to surveys, many medium-sized manufacturing companies have already fallen victim to cyberattacks on production and control systems.
