Radio in times of catastrophes

Warning System: Radio

Radio is an important source of information in times of events like flooding, storm warnings, terror attacks or blackouts. People can be quickly informed and warned about the dangers. In a blackout, it is not only important to have sufficient food and other necessities at home but also a battery-driven or a wind-up radio in order to stay informed. 

Digital Radio

The Radio, the Survivalist!

In spite of numerous competing media like TV, the internet, social media and gaming, the radio is still indispensable in our everyday life. Its decisive advantage is its use as a secondary media. Everyone can decide for themselves whether to consciously listen or not. Radio today is a multimedia platform that can play many different categories.

Everything about DAB+ Radio

What is DAB+?

DAB is the acronym for “Digital Audio Broadcasting”, the successor to ultra-short wave - or metic wave - radio. As opposed to metric wave, DAB+ uses a much higher frequency in which the signals are sent digitally in frames. This form of broadcasting is called “ensemble”. The area in which DAB+ signals can be received is much larger than with metric wave, and the sound is better. In addition to audio signals, and thanks to newer technology, text information can also be broadcast.

How does DAB+ work?

In order to listen to DAB+ radio, a DAB+- capable receiving device is necessary. After plugging it in, the receiver automatically searches for available broadcastings. The advantages of DAB+ are a very good audio quality and the omission of the irritating static in metric wave radio. Many different broadcasts - independent of location - can be received and DAB+ offers extra services like weather maps, news headlines, and the display of song titles and album covers.

What is 5G-Broadcast?

Besides metric wave and DAB+, a new name has appeared on the market: 5G-Broadcast. Many experts see this as the future of radio. Although most of us think of this as mobile sending technology, this can also transfer radio signals. With this, all of the contents of a broadcast can be consumed on a smart phone or tablet without using one’s own data volume or a SIM card. Server overload at live events could become a thing of the past.

Ultra short wave - metric wave - Broadcasting

What is metric wave ?

Ultra short wave or metric wave refers to the length of the electromagnetic waves. A metric wave device sends out electromagnetic waves - these contain audio information. With a radio these are exclusively music or speaking voice. The main function of a radio is to detach this audio information from its carrying frequency and transform them into acoustic waves. The built-in loud speaker or headset sends the acoustic waves directly to our ears.

Radio Mobile

The Comeback of Headsets
Walking with my Radio

After the introduction of transistor radios and before the first MP3-players conquered the market, the Walkman or Discman offered the possibility to enjoy radio and music on the go. If in the course of radio history, headsets were set aside, these celebrated a revival in the 1970s and listening again became an individual experience.

New Phenomena – new Format
Pod… Pod… Podcast

The term “podcast” is a creation from the word “iPod” of the Apple company and the English work for radio, which is “broadcast”. A podcast is an audio format that can either be listened too immediately or downloaded for later listening. The podcasts are received via smartphone, computer or a radio that has wireless LAN.

Frequency Distribution

Wave Regulation

In London in 1925, various European countries, including Austria, together founded the Radio Organization. In 1929, the organisation was re-named the “International Radio Union”. Its main function was the assignment and coordination of radio frequencies. After the war, the European Broadcasting Union (EBU) was created with its headquarters in Geneva. At present, 68 broadcasting entities in 56 countries of the world belong to the EBU. It is responsible for programming exchange, for broadcasting rights and it is concerned with assigning frequencies.
