Mobile World Congress was back in full session for the first time in three years. Barcelona’s premier technology show hosted over 61,000 physical attendees, but with an experience that was markedly different than in years past. The exhibition floors, keynote auditoriums, and meeting rooms had all been reorganized. The revised format inevitably featured fewer exhibitors and wider stands, allowing participants to focus more on substance than style. Many attendees noticed the absence of “bells and whistles,” so demo kits and prototypes were left behind.
