Why should digital radio DRM be used for distance education when radio has been used for it for many years?
DRM can bring a vast selection of new, exciting content and more channels on one single frequency. These new radio programmes transmitted by national and international broadcasters, together with additional multimedia content, can be made available in several languages or dialects, if needed.
DRM can offer distance learning and education to people wherever they are in their country or even further afield, even in remote areas, when distance learning is required. The educational programmes are free-to-air to everybody without the need for internet. The DRM receivers are also capable of caching the information (like schooling documents) for convenient access and study at any time. Distance education via DRM is not dependent on internet or electricity. In DRM up to three audio channels and one data channel can be broadcast on one current frequency. So, you could have three parallel lessons broadcast digitally or in DRM you could allocate two channels for regular radio programmes, while using the third for distance education. Thus, the difference to analogue and the advantages of digital are vast and obvious.
