  • Radio Network Evolution & Spectrum
  • 5G
  • Core  Networks
  • Services
  • M2M
  • India Languages
  • Optical Access & Transport
  • Backhaul
  • Security
  • Energy Efficiency

Issues currently being studied include 5G & related technologies (mmwave, massive MIMO, new waveform techniques), NFV/SDN, 4G evolution, dynamic RAN, embedded SIM, spectrum issues, security and energy efficiency, support for Indian languages on devices (user terminals, mobile network equipment & applications)

TSDSI has initiated a multi-year cooperation project with European Union focussing on the areas of 5G, NFV/SDN and Intelligent Transportation Systems (ITS)
