The Radio Sector of the ITU (ITU-R) has been involved in two aspects of personal mobile communication systems, namely defining the standards and identifying frequency bands related to these systems under the label of the International Mobile Telecommunication (IMT). This paper has investigated...

There have been substantial technical and policy discussions about the spectrum needs of 5G and the necessity of expanding access to the higher frequency spectrum, including in the millimeter wave bands from 30 to 300 GHz. The focus, however, has been on bands below 60GHz, or at most 90GHz,...

Industrial agriculture and its technological package (intensive farming, mechanization, use of chemicals) are no longer in position to ensure food security (Altieri et al., 2012). To overcome the strongly negative externalities produced by this model, agroecological transition may be considered...

The article addresses the lack of focus, in the literature on work and communications technology, on the role played by communities of practice (CoPs) in mediating the impacts of technology change on work. It is argued that the particular characteristics of CoPs, the fact that they are regarded...

The last two decades have seen a lot research devoted to understanding the economic impact of telecoms infrastructure; however, the explosion of mobile technology, especially in the last decade, has received much less attention. This study addresses important evidence gaps by considering the...

Since its introduction in the late seventies of the last century, mobile wireless communication has undergone significant stages of development, from analogue voice calls to nowadays latest state-of- the-art digital technology. The intense development of mobile communications networks, the...
