It is expected that by 2050 about 86% of the world's population shall be urbanized. Even though most people will concentrate around city centres, they will have to commute substantially. Not just going to work can require several hours a day but also every errand, every event people want to participate it. These hours of travelling can be unproductive but once wireless connections to the internet are available, lots of activities can be fulfilled. No matter if public transportation by bus or train, or individual automobile transportation, lots of wireless connections are required. But not only commuting people are causing high data traffic, also the busses, cars and trains themselves will participate in data traffic generation and finally even dominate due to many desireable features in security, safety and fleet control.
The wireless internet today is based on a nomadic use for its participants. In this talk the challenges for future wireless networks to deal with such mass of high mobile users are being set and first ideas to overcome such hurdles with existing and future networks are being proposed. The limitations of the current physical layer are explained, potential solutions such as Hetnets, distributed antennas and eMBMS services are explained in such context. Only few of the recent ideas proposed for 5G networks appear as feasable solutions.
