History of C.C.R.M.

Under Construction


International coordination in radiocommunication is assured by the International Telecommunication Union (I.T.U.), based in Geneva.

Radio related actrivities of I.T.U. were nearly born within the last century. First conferences were held in Berlin in 1903 then in 1906, where focuses were held on mobile radiomaritime services on 1000 kHz, 500 kHz and under. Followings conferences (Washington in 1927 then Madrid in 1932) worked out the first radiocommunication regulations wich included a frequency assignation table from 10 kHz to 23 MHz, and for the first time a frequency accuracy table. The Cairo international conference in broaded those tables to 200 MHz. After second world war, a giant leap was done at the Atlantic City conference which broaded from 200 MHz to 10.5 GHz the table, and then to 400 GHz in Geneva (1959).

The radiocommunciation regulations from Atlantic City conference are much more complex than before, because it considers important technological developments done during the war. Even with the extension of the radio spectrum to higher frequencies, the spectrum congestion becomes a more difficult and sensitive problem.

For the first time (1947-Atlantic City) in the radiocommunication regulations, we hear about control of transmissions. Article 18 of Atlantic City regulation implements an international control of transmissions where national control stations (adiminstrations or private) can take part in.

This is where Belgium pioneered... In 1930, Brussels saw the birth of the first international control station belonging to the International Broadcasting Union U.I.R. (being now EBU/UER). Later, mobile maritime services form the norht sea, took into consideration the needs and advantages of an international control service. The belgian minister of telecomunication saw the same consideration for Aeronautics in 1946, and hence created, one year before Atlantic City, a specific monitoring center for mobile communications... C.C.R.M. was born.
