ARM regulates water, energy and transportation in addition to telecommunications. It was created as part of the process of liberalizing the telecom sector.
DRPT's response to the ITU survey of national spectrum management in 2002 says that the legal bases for spectrum management in Niger are Ordonnance N° 99-045 ["du 26 octobre 1999 portant réglementation des télécommunications" (conveying the regulation of telecommunication)], Décret N° 2000-370/PRN/MC ["du 12 octobre 2000 portant organisation des spectres radioélectriques" (Conveying the organization of the radio spectrum)], and Arrêté N° 0006/MC/DRPT ["du 15 Janvier 2001 - Portant fixation des redevances de gestion du spectre de Fréquences et de contrôle des Réseaux et stations de Radiocommunications au Niger" (Setting fees for the management and control of the frequency spectrum for radiocommunication networks and stations in Niger)]
According to Wireless Networks for the Developing World: The Regulation and Use of Licence-Exempt Radio Bands in Africa by Isabel Neto (June 2004), use of the 2.4 GHz band was licensed but the licenses were issued automatically. There were no unlicensed bands. However, there also was no set power limit, and exclusive channels were available. Only data could be transmitted (no voice or images). The registration form now on ARM's website suggests a similar approach is still being used, but with more band choices and a wider range of allowed content (voice and images).
