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

7
Transition to Future Networks

• Coherent transition to Future networks
• Interoperability with existing systems new
  services
• Number of terminals x5, x10, x100

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, ...

Is the broadband gap growing ?

12
Where are the users in Slovenia

• 96 of households within xDSL technologies reach
• 98 of xDSL households with more than 1 Mbit/s
  possible downlink capacity
• 15 of households with inappropriate copper local
  loop connection for xDSL deployment

13
Technology solutions

• FTTx/xDSL deployment
• Optimal remote broadband network elements
  placementproblem
• Optimal timing for migrationscenario is market
  driven
• Inappropriate return of investment (ROI) in rural
  areas

14
Fixed Wireless Broadband

• Rural area definition is crucial
• population density, GDP
• lt 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)
• lt 1 GHz frequencies for WiMAX at 450 MHz gt
  digital dividend policy
• lt 1 GHz frequencies for UMTS/HSPA/LTE at 450 MHz
  gt digital dividend policy (?)

15
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
• with various technologies consideration (not only
  one)
• with techno-economical extensions

16
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

Conclusion

• Generic research critical mass of companies
  knowledge
• 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

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.
