Wireless Access Systems

This team aims to maximize the vitality of the mobile ecosystem in the long-term by developing technologies for future business and regulatory models.

Among the research targets are:

• The development of new radio access technologies from the basis of underlying regulatory and business assumptions.
• Compose new regulatory models and influence Nokia's future regulatory vision and its implementation.
• Verify techno-economical feasibility of assumed technology-business-regulation combinations.
• Complement and challenge the main cellular standardization tracks in 3GPP and IEEE.
• Develop component technologies for radio systems of IMT-A era in a system neutral way.
• Transfer of developed component technologies to later use in other activities.

Research topics

• IMT-A/LTE-A activities in 3GPP
• Flexible Spectrum (Resource) Use
• Device-to-device communications
• Techno-economical modeling
• Celtic/WINNER+ project
