As many as 13 simultaneous sessions. Many of the world's best engineers are coming to the IEEE International Conference on Communications, from the most advanced academics to the slickest salesmen. Hundreds of presentations, far more than anyone can absorb. Alcatel, Ericsson, Huawei, Nokia, Samsung & ZTE will each explain why they and they alone have the right path to 5G. Of course, none of them can even provide an agreed definition of what 5G is or are even close to delivering relevant equipment. (Marketing is like that.) In particular, experts like NTT are saying one much discussed "5G' technology - high GHz millimeter waves - is unlikely before 2022-2023. http://5gwnews.com/90-r/211-2022-or-later-for-high-ghz-5g This will be a conference where I can learn just how far along each technology is in 2015.
Lajos Hanzo's "A Stroll with Shannon to Next-Generation Plaza: Large-Scale MIMOs, Single versus Multiple RF Chains and All That..." promises to be particularly interesting. Filming Stanford Professor Andrea Goldsmith, I asked "What are the most interesting problems in communications? What would you include if you were creating a list after Hilbert's?" Her first answer was "Extending the notion of a limit from Shannon's single wire to today's multiple channels."
