People – and animals – have been communicating wirelessly with each other since prehistoric times. And we’re not talking about burning wood to send smoke signals that Native Americans used to send to a tribe in another location, or by playing drums like one African tribe does to send a message to the other. No, wireless communication is what people always do when they talk to each other. After all, there is no wire between two faces at a short distance from one other. You can understand each other like that, even if, as is usual in times of corona, there is about a meter and a half distance between you and the other person.
Innovation Origins will focus on the increasing influence of wireless communication in society by means of data traffic using electromagnetic waves with increasingly higher frequencies such as 5G.
What we mean by wireless communication these days is that we can talk to each other via countless invisible electromagnetic waves. These are sent through the air from a transmitter in a base station to a receiver, in the form of a mobile phone or another device, that can receive the signal and convert it into information.
Nowadays we’re used to being able to organize everything from home. From a computer, cell phone or iPad we can make video calls, watch movies, send messages, call Australia for free via Whatsapp from the Netherlands or Germany, and so on. The possibilities that digitization has brought us seem to be infinite. And maybe they are.
However, the technology used by every generation of mobile telephony – and which is increasingly turning into mobile data communication – does have its limits. For example, the spectrum for the radio frequencies we use for fourth generation wireless communication is saturated. The technology used for this is called – not surprisingly – 4G. There are so many people and machines using these 4G frequencies that there are blockages in the network that slow down or weaken the signals reaching the receivers.
For this reason, a next generation is in the making, called 5G, which will enable us to communicate even more data via even higher radio frequencies in the coming years. And when the limits of that are reached, we will get 6G, which will make use of even higher frequencies and even visible light that will allow us to surf the internet via a lamp that we will have to sit under.
