 Well it's fundamental because it's such a complex word, 5G, it means so many different things, so many different technologies that need to be brought together and to cooperate the technologies in its large cooperation in the specialists that work at them. Well actually that's a bit the part that needs to be sorted because at the beginning of a new trend, a new wave of change in the world of technology, everyone focuses on everything basically, so one of the things to do is to sort the items each group works on according to the best skills they have and then establishing good cooperation between the groups is what follows and can bring results. Well technical packages are a way to group the production we have in terms of recommendations according to certain technology areas that are the most important, the most urgent and what this is a help for the users first off which will, who will be able to find the things that they want to know about in the area that the technical package individuates and for other groups as well because they will know what the SG-13, what working party one have done in that specific area and what they didn't do because the skills were not matching certain topics. Well it's essentially to move from the situation in which you have many many different devices that are managed individually or network areas that are managed individually, mobile, fixed, IoT, where we have a very tight separation between what they are called silos, each of them focusing on a single aspect, on a single service, all that will have to be managed in an integrated way and that's a huge change which can come only through softwareization which is one of the keys for our work. Well softwareization is an extension let's say of virtualization, in virtualization you just make what was a physical piece of equipment become something software running on a simple piece of equipment and very standard off the shelf. With softwareization you extend the concept to also the management and all the control of the network and all the layers of the network. So it's a global change in the way communication networks work.
