The T-DAB broadcasting service networks implementation plan in Europe and allocation of frequencies to each country was initially drawn and adopted at CEPT ERC planning conference in Wiesbaden, Germany in 1995 (Wiesbaden, 1995, Special Arrangement as subsequently revised in Bonn 1996). 73 frequency blocks were dedicated for the entire system. The range was allocated in the following way: 12 blocks in the VHF II band (87 MHz-108 MHz), 38 blocks in the VHF III band (174-240 MHz) and 9 lower in the L-band (1.452-1.467 GHz).
The ITU WARC conference, held in 1992 assigned the entire frequency band of the L-band (1452-1492 MHz) to regions 1 and 3 of the ITU for the purpose of broadcasting of digital radio to terrestrial and satellite (S-DAB) systems according to the common rights. During the T-DAB frequency planning conference of the CEPT countries, held in 2002 in Maastricht, the Netherlands additional 7 blocks were used for the T-DAB purposes. Special Arrangement and Allotment Plan for T-DAB was adopted. All the conditions of the Wiesbaden agreement, relating to the 1452-1492 MHz band were transposed to the Maastricht Special Arrangement as actually revised in Constanta 2007.
In the Wiesbaden plan the 13C horizontal polarization block in the 230-240 MHz frequency band was assigned to Lithuania’s national coverage. Later on, due to the possible interferences to the aeronautical services of the neighboring countries said block was modified to 13A (230.784 MHz). In addition L-band blocks were assigned to five regional allotments around the major cities of Lithuania. In the Maastricht Special Arrangement (rev. Constanta 2007) Lithuania’s plan of 40 allotments was drawn including 5 newly allocated frequencies and the conditions for coordination of the said frequencies between the administrations were established.
The Regional Radiocommunication Conference for the planning of the digital terrestrial broadcasting service in Region 1 (parts of Region 1 situated to the west of meridian 170° E and to the north of parallel 40° S, except the territories of Mongolia) and in the Islamic Republic of Iran, in the frequency bands 174-230 MHz and 470-862 MHz, was held in Geneva, 2006 (RRC-06). Regional Agreement and associated frequency plans were drawn up by the Conference. The digital frequency plan of Lithuania in the range of 174-230 MHz consists of three T-DAB and of one DVB‑T nationwide networks.
