Scientific Director Jens Zander gives invited talk at ETSI Future Mobile Summit Nov 21, (Cannes-Mandelieu, France) The talk was entitled “Spectrum for 5G – a big deal?”, and addressed the divided world where we have a ”coverage world” (evolution of traditional cellular) where coverage, any-time any-where is premium, and the capacity world (indoor short-range), where high data rates are provided for a dense user population at low cost. The spectrum solution has very different solutions in these two cases. Indoor there is plenty of potential spectrum above 3 GHz allowing for huge traffic capacities. In the coverage world, there will be continued demand for spectrum, mainly to make the wide-area services more affordable as traffic grows.

A little belated, but the slides from Alf Ericsson’s, Edgeware, seminar on Challenges with building high capacity Internet streaming networks are now available.
In September, Wireless@kth Assisting Center Director Mats Nilson was approached by a student – Annica Heldt – at Medborgarskolan, studying to be a qualified researcher. As part of her studies she was assigned to do an interview-based article on some contemporary topic.

Abstract: Energy efficiency in mobile radio networks has recently gained great interest due to escalating energy cost and environmental concerns. Rapidly growing demand for capacity will require denser and denser networks which further increase the energy consumption. In this regard, the deployment of small cells under macro-cellular umbrella coverage appears a promising solution to cope with the explosive demand in an energy efficient manner.

Abstract: The large expected increase in the capacity requirements raises not only technical issues but also regulatory and business challenges. One of the key methods to increase the capacity of mobile networks in a cost efficient way is to find additional frequency spectrum.

Abstract: Unlicensed spectrum indeed initiates high-data rate wireless services with thecombination of the great success of Wi-Fi technology. Interestingly, the local high datarate services are deployed and invested by non-traditional local actors, e.g., facility owners who have local fixed line infrastructure.
