    • Broadband services 5
    • Future Networks and Services  Broadband “Wireless internet interface« and “RJ45” connector have become similar to 230 V electrical plugs  Net connectivity has become commodity, expected to be everywhere  Today applications (i.e. VoIP, HSI, IPTV/HDTV) are with broadband internet becoming ubiquitous – convergence is happening  However, users always find ways to “fill the pipes”  Billing/Charging  Flat rate for majority of users (free and fully unlimited ?)  Some users willing to pay premium for “classical telco services”  Additional ways to colect money - Advertisements  New protocols - IPv6/IPv4 – the toothpaste effect  You squeeze the toothpaste until to a certain point, then you give up (too much effort for the giver results) and buy new one 6
    • Transition to Future Networks  Coherent transition to Future networks  Interoperability with existing systems + new services  Number of terminals x5, x10, x100 7
    • What Services – a future look ...  Social-networking, location, presence  Video, multimedia content & interactivity  Services that are integrated into private and business processes/life  Communications, traffic, health, learning, entertainment, energy sustainability, eInclusion, local activities, ... 8

SLO < 175 inh./km2 < 150 inh./km2 < 125 inh./km2 < 100 inh./km2 < 75 inh./km2 < 50 inh./km2 < 25 inh./km2 /km2 population density 97 67 66 61 57 51 41 30 16 households density 34 23 22 20 19 17 14 10 6 13
    • Fixed Wireless Broadband  Rural area definition is crucial  population density, GDP  < 10 households/km2 = capacity is not a problem …  Reach, not capacity, constrained constrined planninng,  Considering “1 Mbit/s like” downlink capacities  WiMAX at 3,5 GHz = ~ LOS PHY channel  poor rural coverage in hilly “type A” terrain (IEEE 802.16-20004 standard)  < 1 GHz frequencies for WiMAX at 450 MHz => digital dividend policy  < 1 GHz frequencies for UMTS/HSPA/LTE at 450 MHz => digital dividend policy (?) 14
    • Combination of Technologies  To deliver “broadband for all as soon as possible” the optimal solution is a combination of broadband access technologies  Step by step broadband capacity upgrading:  Urban areas: from “xDSL speed” To “FTTH speed”  Rural areas: “modem speed” To basic “xDSL speed” (with xDSL/FTTx access network combination) or “WiMAX speed” To “FTTH speed”  Broadband access planning optimization tools CO  with various technologies consideration (not only one)  with techno-economical extensions 15
    • Optimisation planning tools  Considers real copper network topology  Calculates optimal remote access network elements placement  Calculates techno-economic outputs  Net present value, rate of return  Comparison with FWB sistems is “in progres” 16

    • Abstract  Next generation broadband technologies evolution and consequently much higher user bandwidth demands are the main drivers for deployment of high speed broadband access networks. In urban areas with high population densities, broadband services are already well assured. In low-populated rural areas the return of investment is the main disadvantage for faster broadband rollout, thus leading to digital divide. Deployment of broadband access networks with the mix of xDSL, FTTx, and wireless technologies also below 1 GHz may be optimal solution, considering decreasing range of xDSL technologies and vast investments needed for fibre to the home solution.  Based on the pure broadband networks, converged platforms and services are gaining momentum, integrating communication, mobility, collaboration, education, communities and content. These are typically based on new technologies, e.g. Web 2.0, P2P, Grid and IMS. Network and service openness based on open interfaces is important to continue fast development of future networks, thus enabling many companies and individuals to become the drivers of development, thus decreasing the digital divide in the converged services area. 26
