Wireless: wireless data transmission

Wireless data transmission transmits data in the form of electromagnetic waves. These waves are sent and received via antennas. But how exactly does data transmission by radio work? Find out more here about how wireless data transmission works and various wireless systems.

 

How does wireless data transmission work?

Wireless data transmission is a process which, as the name suggests, no longer relies on a cable as a conductor for the transmission of data. Instead, the data is transmitted via air or a vacuum. Electromagnetic waves are transmitted in different frequency ranges. This makes data transmission much simpler and more effective.

 

Different wireless data transmission systems

Wireless data transmission systems, also known as wireless systems, differ primarily according to the use of different frequencies. The frequency indicates how often a wave is repeated per second. This is always specified with the unit Hetz. Basically, higher frequencies have a higher radiation energy. The size of the antenna also depends on the frequency used. The basic rule here is: the higher the frequency, the smaller the antenna.

 

Radio transmission via antennas

Radio transmissions can extend over a large distance. Antennas are indispensable for this. The type of antenna also plays a key role in data transmission. While rod antennas are used for both sending and receiving data, directional antennas only work in one of these directions.

 

Obstacles in the transmission

Of course, the radio range is best in direct line of sight. If obstacles get in the way, this can have a negative impact on the radio signal. This is the case, for example, when large buildings or sheds block the path. In addition, the reception of radio signals is influenced by other electrical devices in the vicinity.

 

Wireless data transmission: Advantages

As the name suggests, no cable is required for wireless data transmission. The annoying tangle of cables is therefore a thing of the past with wireless systems. Transmission takes place exclusively via directional or non-directional electromagnetic waves. This makes the world of digital communication more flexible than ever before. What's more, wireless data transmission systems are generally much more cost-effective.

 

Application areas of wireless systems

The best-known wireless system is probably the WLAN (Wireless Local Area Network). A WLAN router receives an Internet signal via cable and forwards the corresponding data to all connected devices via a wireless connection. However, wireless communication systems are also used daily in the areas of satellite communication and directional radio. Radio waves are directed to a defined point in time.

Wireless systems also play a key role in consumer electronics. Above all, Bluetooth technology is becoming increasingly important in this context. Bluetooth works in the same way as WLAN, but Bluetooth technology does not require a router. The corresponding devices are connected directly to each other wirelessly.

 

Wireless data transmission in the conference room

During the coronavirus pandemic, a lot has changed in the field of conference room technology. Digital communication has become even more relevant since then. Wireless systems are also increasingly being used in conference rooms.
