In the field of computer science and telecommunications, the term wireless indicates a communication between electronic devices that does not use cables. Instead, traditional system based on wired connections are called wired.
Generally the wireless technology uses low-power radio waves, but the definition also extends to less widespread devices, which use infrared radiation or laser.
Wireless communications are now used in many situations that characterize our everyday life. Just think of the revolution introduced by the Internet and the access point that have allowed the elimination of cables in both domestic and public environments such as airports or universities where it is now possible to connect to the wireless mobile network.
Today, in the “fourth industrial revolution era”, is changing the way of producing more and more oriented towards the use of wireless connections and low-cost sensors, a process that contributes to strengthening their growth trends.
This is seen in the automation of process, factory and buildings where the use of wireless solutions greatly simplifies plant management. The acquisition of operating data is thus much easier and at the same time faster, and allows refining the control and taking intervention decisions more quickly, automatically or not.
The Industry 4.0 relies on the Internet, more precisely the Internet of Things (IoT): that is connections that can be made between devices equipped with sensors, software and wireless functionality, along with an increasing ability to collect and store data.
This is why Wireless Technology fits perfectly with the mega trends of Industry 4.0 and with the consequent so called “digital factory”. Greater connectivity and data sharing play a significant role in alleviating a range of problems, including remote locations, widespread supply chains and potentially dangerous work environments.
