5G – “Mädchen für Alles?”

Listening to Sara Mazur (head of Ericsson Research) at last years Johannesberg Summit really puts the spotligth on the main dilemma in 5G: I should do this, and that, and also this etc, in an almost endless “wishlist”. Other constraints are lower cost, lower energy and that it creates (more) new business for the existing operators. The discussions seems to have matured somewhat now and at this years edition of the Summit we should make it beyond the wishlist. Is 5G a “Mädchen für alles”, solving all problems with “more of the same”, an improved “4G” (cloud-servers and best-effort IP-capacity), or are some of the applications so demanding (e.g. the ultra-reliable machine communication) that they require separate technical solutions. Does the latter bring us back to the days of the hated “killer app”, i.e. the single application that will pay for these infrastructures? In any case, at the end of the day, it’s the one that “foots the bill” that will have a final say on what’s important on the wishlist, and what is not.
