Millimeter Wave vs. Below 5GHz Massive MIMO: Which Technology Can Give Greater Value?

The purpose of this panel is to discuss and debate the inherent technical merits of the two most prominent fifth-generation (5G) wireless physical layer technologies: millimeter wave, and below 5 GHz Massive MIMO. Despite the fact that the efficacy of wireless technology is thoroughly testable by controlled, reproducible experiments, there is apparently little consensus within the wireless industry as to the best direction future technology should take. Too often technical discussions are diluted by the introduction of extraneous nontechnical factors, such as spectrum licensing policy, the reluctance of service providers to replace wireless infrastructure ahead of its projected lifespan, entrenched thinking that has the force of dogma, and the pressure of "not invented here." Attaching excessive importance to merely subsidiary considerations ignores that fact that the wireless industry is exceedingly wealthy (service providers spent more than $40 billion on 65 MHz of spectrum in the 2015 FCC AWS-3 auction) and that advanced communications are of ever increasing importance to young people for which they can be expected to pay increasing fractions of their income.
