9 New traffic types from potential new fields Urgent: Fixed Cope and with Mobile enormously communications increasing Traffic traffic in (on Japan going story in 4G networks) Foreseen: Handling of genuine mobile specific traffic. (New type traffic) X 10 within 7 years! X 100 within 14 years? X 1000 in 21 years??? Depending on Cost vs. Value provided Mobile specific traffic (Mobile specific applications) Mobile specific traffic Genuine new Fixed comm.

10 A case study Basic exercises on demographics of Japan and Tokyo 10

11 An exercise to see practical 5G deployment: The ways to cope with demanding communication traffic 1. Improvement of spectral efficiency 1. Improvement of spectral efficiency Applying Applying OFDM OFDM based based efficient efficient radio radio access access technologies technologies as as in in LTE. LTE. 2. Utilization of wider frequency spectrum Development of higher spectrum in EHF or SHF. 3. Higher spatial reuse factor Deployment of smaller cells How many small cells do we need? Dynamics of the traffic? A macro-scopic simple exercises follow: (Note: The following exercises do not intent to provide actual deployment scenarios.) 11
