Towards 5G...

• Radio channel modeling and experimental research
  focusing on spectral efficiency improvement by
  employing spatial radio signal modulation.
• Influence of environmental factors on
  heterogeneous network design and performance.
• Impact of LTE 800MHz signal on digital
  terrestrial television services (DVB-T)
• Participation in Horizon 2020 program, Advanced
  5G Network Infrastructure for Future Internet.
• What is 5G? 3D/Massive MIMO (Multiple Antennas),
  network densification, non-orthogonal multiple
  access.
