MOOC as a way of dissemination, training and learning of telecommunication engineering

In this chapter, the use of massive open online courses (MOOCs) for the dissemination, training capabilities and learning of telecommunication engineering is described taking as example the successful MOOC ``Ultra-Dense Networks for 5G and its Evolution'' developed under the European innovative training network (ITN) TeamUp5G. MOOCs are usually understood as a way of teaching or learning for massive potential students. Indeed, this is the main goal of any MOOC. However, we also propose its use for training and dissemination. The ITN TeamUp5G is a training network for 15 PhD students of 7 different institutions (universities and companies) where the students make research on different interconnected topics for the common goal of Ultra dense networks for 5G. At the same time they researched, they prepared a MOOC to disseminate their most recent advances and their challenges. In order to do this, general background and specific scenarios must be addressed, creating an organized structure. In this way, they needed to collect their thoughts, organize their knowledge and establish a common vision of the whole system. The cooperative work, the cross-related meetings, the preparation of all the materials for the MOOC were very interesting and useful in their training process, so the MOOC could be considered as a tool for these purposes too. The whole experience of designing and creating the MOOC is described in detail along with the challenges and the lessons learned.
