Innovation in the IP Environment
Two overall effects:
Changes in Technology
- Separation between network technology and services
- Intelligence moved from the core to the edge of a
network
- Scalability
- Distributed design and decentralised control
Changes in products/ markets
- access to multimedia applications regardless of the
device used or the type of network connected to

The Internet
In the beginning primarily used for
- data services, E-mail and World Wide Web (WWW)
Today:
- a variety of audio/video services like Internet radio
and TV, B-logs, computer games, etc
Future:
- ‘Internet of things’: RFID and ‘sensor networks’
Internet Protocol (IP) design principles
- Distributed design and decentralized control

Internet services
- Examples of Internet’s impacts on media servcies

Next Generation Networks (NGN):
A specific network architecture and related equipments, with one
common IP core network deployed for the entire legacy. Relates to
the transition of current dedicated voice (and radio/TV) networks to
the IP based networks:
- Next Generation Core Network (NGCN)
the new switching, gateways and transmission equipments in the core
network, enabling several access networks to use the same core network
- Next Generation Access Network (NGAN)
new access networks, as deployment of optical fibers, and the associated
challenges

NGAN: Fixed networks
Main access technologies are xDSL and cable modem.
- Main development tendencies for these technologies:
Extension of coverage
Increase in capacity per connection.
Unbundling
Bitstream access
Other technologies
- FTTx
Capacity is almost a ‘non-issue’ but of course high capacity has high cost
In the current provisions of FTTH from energy firms, figures of 2 – 10 Mbps
and up to 100 Mbps can be identified
The main deployment of fibre is in the backbone network of the
new/alternative broadband operators
- PLC
Availability of infrastructure in the households, No need for wireing
High bandwidth: started around 1 Mbitps but know 45 Mbps modems are
available

NGAN Technologies
- Wireless
WiFi
- Unlicensed Industrial, Science and Medical (ISM) band (The
IEEE 802.11b standard). Absence of licensing barriers, the
simplicity of the technology and cost effectiveness
WiMAX
- the IEEE802.16 standard for fixed wireless access; it is
expected to go mobile in 2008.
Digital broadcast infrastructures
- Not worldwide standards and different markets apply to different
standards: European DAB &DVB, US ATSC or Japanese ISDB
standards.

VoIP Scenario
Calls from PSTN to IP & from IP to PSTN, using a gateway
Characteristics:
•IP terminals are computers, mobile phones PDA’s and dedicated IP phones.
•Calls can be placed both to and from a traditional PSTN telephone.
•Advanced signaling systems are being used

Conclusion: Impact on the Telecom Market
Vertical Separation of Networks and Services
Service and Network Convergence
Death of distance and cheaper bandwidth
Low cost wireless access in rural areas
Change of the fundamental cost structures and
investment patterns in the ICT/ telecom sector
Infrastructure as well as applications, services and
content oriented technology are changed
Market Convergence
New business models
Direct implications for developing countries.
