  1. Mobile CommunicationsChapter 11 : Outlook The future of mobile and wireless networks – Is it 5G? All IP? Licensed? Public? Private? Prof. Dr.-Ing. Jochen H. Schiller www.jochenschiller.de MC - 2016

  2. Mobile and wireless services – Always Best Connected LTE, UMTS 2 Mbit/s LAN 100 Mbit/s, WLAN 54 Mbit/s GSM 53 kbit/s Bluetooth 500 kbit/s LAN, WLAN 100 Mbit/s UMTS 2 Mbit/s GSM/EDGE 384 kbit/s, WLAN 5 Mbit/s LTE 10 Mbit/s GSM 115 kbit/s, WLAN 11 Mbit/s Prof. Dr.-Ing. Jochen H. Schiller www.jochenschiller.de MC - 2016

  7. Key features of future mobile and wireless networks • Improved radio technology and antennas • smart antennas, beam forming, multiple-input multiple-output (MIMO) – see LTE, 802.11ac • space division multiplex to increase capacity, benefit from multipath • software defined radios (SDR) • use of different air interfaces, download new modulation/coding/... • requires a lot of processing power (UMTS RF 10000 GIPS) • dynamic spectrum allocation • spectrum on demand results in higher overall capacity • Core network convergence • IP-based, quality of service, mobile IP • Ad-hoc technologies • spontaneous communication, power saving, redundancy • Simple and open service platform • intelligence at the edge, not in the network (as with IN) • more service providers, not network operators only Prof. Dr.-Ing. Jochen H. Schiller www.jochenschiller.de MC - 2016

  11. Potential problems • Quality of service • Today‘s Internet is best-effort • Integrated services did not work out • Differentiated services have to prove scalability and manageability • What about the simplicity of the Internet? DoS attacks on QoS? • Internet protocols are well known… • …also to attackers, hackers, intruders • security by obscurity does not really work, however, closed systems provide some protection • Reliability, maintenance • Open question if Internet technology is really cheaper as soon as high reliability (99.9999%) is required plus all features are integrated • Missing charging models • Charging by technical parameters (volume, time) is not reasonable • Pay-per-application may make much more sense • Killer application? There is no single killer application! • Choice of services and (almost) seamless access to networks determine the success Prof. Dr.-Ing. Jochen H. Schiller www.jochenschiller.de MC - 2016
