CTL is in the process of developing a roadmap that identifies key gaps and R&D opportunities related to future generation communication systems. This effort can prove valuable to informing and planning future R&D activities.
Following an initial market research and over two dozen stakeholder interviews, a number of key wireless technology areas have been identified including waveform, antenna, spectrum, millimeter wave, architecture, and protocols. NIST is convening a multidisciplinary stakeholder working group in July 2016 to further characterize the gaps and challenges related to these areas.
The project wiki features NIST's research early findings and contact information for stakeholders to get involved with this process: https://sites.google.com/a/corneralliance.com/future-generation-wireless-roadmap/home
