The International Amateur Radio Union (IARU) is a federation of national associations of certified radio amateurs, representing over 150 countries and separate territories around the world.

The three IARU Regions are organised to broadly mirror the structure of the International Telecommunications Union (ITU) and its related regional telecommunications organisations. The Regions comprise:
- IARU Region 1: Europe, Africa, the Middle East and Northern Asia
- IARU Region 2: The Americas
- IARU Region 3: Asia-Pacific

The IARU represents the interests of the Amateur Radio Service worldwide to relevant international organisations, promoting the interests of amateur radio and seeking to protect and enhance its spectrum privileges.

The 472 kHz and 122,25 GHz bands available in Poland

As the National Table of Frequency Allocations has been amended, there are two new bands available to the Polish radio amateurs: the 472-479 kHz band (up to 1W e.i.r.p.), and the 122,25-123,00 GHz band - both allocated to the Amateur Service on a secondary basis.

According to the Regulation of the Council of Ministers of 27th December 2013 (Journal of Laws of the Republic of Poland of 3rd February 2014, item 161), the relevant amendments will enter into force on 18th February 2014.
