Future Networks and ServicesFuture 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

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 (?)

CombinationCombination of Technologies 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”

Had very positive influence on the development of broadband Slovenia is in size and population perfect for country wide pilot
projects (infrastructure and services) ... IPTV, UMTS/HSPA, MPEG4, local portals
Networks Urban: up to 3 optical connections (already) Rural: from “modem/xDSL” to optimal mix of fiber/copper/radio Tehno-economic optimisations in order to bring broadband to as
many user as possible
Open issues Digital divide (gap), growing? Universal broadband service/connection obligation? How to stimulate operators to build in rural areas

AbstractAbstract 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.
