telephony• Low capacity• Limited local

and regional coverage

Second Generation

• Digital• Circuit switched• Voice plus basic

data applications• Low data speed• Enhancements

towards• packet switching

• higher data rates

• Trans-national and global roaming

• Digital• Packet and circuit

switched• Data and

multimedia applications

• Medium data rates• Global coverage• Global roaming

Third Generation Beyond IMT 2000

• Digital• Packet switched• All IP based (IPv6)• More advanced

multimedia applications

• User in control• Flexible platform

of complementary access systems

• High speed data• Improved QoS• Global coverage• Global roaming

BEYOND IMT 2000: PROTOCOL ISSUES

New opportunity for DVB-T?

unspecific information to all users in a given area broadcasting

Large memories introduce paradigm shift:– - ‘live services’ are already becoming the exception– - mass storage in receivers decouples consumption

from production (c.f. TV-Anytime) filter & store in user terminal local interactivity on stored content reaction by mobile communication (e.g. order a

product)

Integrating a 512 MB flash in the User Terminal should not be an issue in 2006; today prices of Flash EEPROM is around 0,3 €/MB

Capacity increase exceeds Moore’s law: factor 2 every year, at constant price

Based on present trends, a 0,01 €/ Mbytes could be reached in 2008

THE EU APPROACH TO>IMT 2000

CONCLUSIONS

EU fully committed to support the development of Systems beyond IMT 2000;

Approach based on interoperability and co-operative inter working of heterogeneous networks;

Standards will be critical to the overall success;

Standardisation requirements likely to move towards higher layers;

Standards time frame around 2007 ?;

Co operation between a multiplicity of fora may become critical
