8 Smart Cities Applications General requirements: Integration of security and privacy-preserving mechanisms, to achieve user consent, trust and acceptance Inclusion of mechanisms to deal with complex systems, e.g., interoperability Consideration of a coherent integration of related authorities, businesses, and administrative structures, for sustained development and sound business model. 8

9 Smart Cities Applications Common Technical requirements : Service discovery, scalability and survivability, and interworking with other networks Flexible, redundant and self-optimised networks; Heterogeneous systems and networks (e.g., different sensor and actuator technologies, and radio interfaces); 9

10 Broadband Communications Big Question Mobile Internet IMT-A What is Next and Why?

11 Mobile Broadband challenges Users perspective Ubiquitous broadband Internet services, On-The- Move, particularly video-based services Simplicity in accessing device (s), and services irrespective of network technologies and media (wireless and wired) Long time between re-charging and new and ubiquitous mechanisms for charging of devices Unnoticeable latency in service access and service continuity Dependable and reliable networks; Trusted services and networks; Trust in aggregate level of exposure to Electro-Magnetic fields

12 Enabled by smart phones and broadband mobile Trends and Drivers The Internet!

13 Internet Services Trend Web pages getting more complex o Avgweb page size has tripled in past 5 years o +75% HTTP requests from images, up from 20% in 03 o +90% of web pages have images today Video and HD are here o Average file size on the web = 10 MBytes o Video accounts for ~99% of all bytes transferred o And they are growing in size and length; 90% of videos are +3min, up from under 1 min in 97

14 No of Mobile Phones Market Trends and Drivers compared with Bn 1 Petabyte 100 Libraries of Congress by 2015 by 2020 Every person with a phone Mobile traffic 26 fold (CISCO) 1000fold Mobile to Mobile traffic; 295 Petabytes per (DOCOMO and month Huawei) Expenditure (mobile Services alone) Video 2/3 of Traffic One Second of video uploads on Net takes Two Years to watch $1.7 Tn(Generator an Industry insight) $2.89 Tn

15 Challenges in Broadband Radio Access Provision of 50Mbps (throughput) per user even up to 100Mbps Ubiquitously available (not only hotspots) 1000 times more capacity Questions: Will there be sufficient spectrum? NO If not, how to meet such challenges? At what cost?

16 Telecom Industry Challenges Capacity crunch and provision of 1000-fold capacity relative to 3GHSPA in 2010 Wide-area and long-range; at least 10 times more throughput than HSPA Short-range; 10 times higher throughput than in the wide-area; Scarcity and high fragmentation of suitable spectrum and lack of global harmonisation; Wireless Backhaul spectrum shortage; Need for faster service creation, test and deployment Need for multi-service and evolvable networks; Inter-operability between different standards and technologies; Support of machine to machine (M2M) traffic and cost of associated signalling; Increasing demand in processing power and storage; Ever-increasing complexity in management of systems, number of networks and increasing traffic. Leading in turn to escalation of costs associated with system operation, maintenance, and overall energy requirements; Cost-effective solutions for migration of legacy services and networking to new networking solutions; Cost of long-term research and global competition

17 Spectrum Crunch WRC 16, Twice more spectrum at best- leaving 500 times Offloading, Twice at best- leaving 250 times Rest should come from: 1. Intelligent cooperation between different RATS 2. Intelligent cooperation between cells 3. New solutions for higher cell throughput 4. Higher Frequency reuse 5. Cognitive use of spectrum 6. Interference Management (a prior knowledge) 7. Technology-independent spectrum allocations 8. New spectrum

18 Are we using the spectrum efficiently? Current practice Cell dimensioning and operation on per cell basis Excellent Adaptive techniques at link level but NOT at the system level Low utilisation of available Capacity Unstable capacity over time and over cells

19 Capacity Increase factors since 1950

20 New Architectures Cooperation converts the distributed cellular system into a MIMO system with distributed antennas

21 Radio Access Architecture Types of cells based on dimension Mobile device== smallest cells Distributed antenna systems Fixed relay Small cell Macro cell Base stations cluster cell BS cooperation at radio access BS cooperation at wireless Backhaul

22 Backhaul architectures Fiber optics What point transform from Electrical to optical signals Wireless Adaptive Mesh architecture for high spectral efficiency and adaptive to temporal and spatial traffic variations Joint Processing and Resource Management of multi-cells (Cloud) Co-design between radio access and backhaul

23 Sum Up on Broadband Radio Beyond 2020 System level research Small cell technologies Joint design of Radio access with wireless Backhaul Multi-cell operation and cooperative techniques Intelligent Combination of Small and Large cells Opportunistic use of spectrum (Liberate technology from Spectrum) licensed and licensed- exempt bands and systems

24 Challenges of Fixed Networking and Management Different Radio access technologies are operated and managed separately Radio access specific Service specific Every 10 years new architecture Management cost escalating
