Standards and interoperability – Do they matter for ETPs?

If so, how far can we/should we go?

AAS position wrt ETP

Alcatel Alenia Space is part of the Integral Satcom Initiative http://www.isi-initiative.eu.org/

Strategic position of ISI is to develop applications integrating satellite communications inside telecom infrastructures

ISI gathers numerous partners (149 institutions/ 24 countries)Reaching a Critical mass is an issue

Benefits of standards for Satellite applications

Standards for Satellite systems In Europe, very few launch of satellite services from a single

operator Multiple partnerships, over nations and time Concatenation of niche markets Long-term applications (>10 years)

Standards are a must to get Team-building between partners Reliable return on investment Future-proof solutions

Example of standard-initiated project : MOWGLY (DVB-RCS)

Key issues

Standards for Satellite systems Future Satellite systems will be embedded into operators

offers Even broadcast TV becomes hybrid

Seamless integration is a targetUse of standards at all layers

Interoperability is a mustInteroperability testsFine tuning Typical example of mandatory integration

is for emergency services Offer a quick restitution of (reduced)

terrestrial services (Broadband, mobile) No particular training or test phase is allowed

Producer or Consumer ?

Standards Producers Low layers are specific to satellite

Specific antenna systems/ regulatory constraints Link budgets Propagation channel

Standards Consumers No (or few) link layer or application is dedicated to satellite

usage Integration with satellite links constraints should be tested if not

considered by design
