IEEE published a white paper summarizing the challenges and opportunities in building and sustaining a 5G and beyond ecosystem.

“5G consolidates the trend in convergence of technologies and underlying standards with emerging solutions offering exciting possibilities not only to consumers but also to industries,” said Mischa Dohler, co-chair, IEEE 5G and Beyond Technology Roadmap Working Group. “Disruption will happen at many levels, most importantly through changes in the value chain, adoption of flexible systems management and orchestration, as well as emergence of innovative mobile connectivity technologies.”
