6. Potentially available spectrum for beyond 3G systems may require infrastructure sharing
Sharing between different systems for different applications under discussion
Depending on available spectrum from candidate bands potentially infrastructure sharing required to support

Implementation and Deployment
The implementation and deployment of systems
based on global specifications and standards is
following a value chain from
basic research
national, European and general research activities towards
research in the industry
in the pre-competitive domain.
These research results influence significantly the
global standardisation and regulatory process and
contribute to consensus building and harmonisation
of specifications and standards.
This allows the economic exploitation of research
results in the competitive domain with
economy of scale
inter-operable systems and the
support of global user and terminal roaming

Increased maturity makes consensus building difficult
Increasing IPRs portfolios make consensus building difficult
Increasing investment in solutions
Increasing IPR portfolios
Chance for consensus
building
Chance for consensus building decreasing
Early cooperation in the research phase is the key for international consensus building and harmonisation to prepare future specifications and standards.
In the early stage system concepts are immature and IPR-portfolios are not built-up.
This is the time window for successful cooperation and the joint development of new systems.
If cooperation is starting in the standardisation phase, harmonisation is becoming more difficult due to the transition from the pre-competitive to the competitive domain.
In the final competitive phase of product development harmonisation is becoming very difficult, if no common standards are available.
Therefore, let’s start cooperation early in research on global basis in the interest of the community.
