In November, about 400 smartphone users finally got a chance to do so — in Beijing, China. The next big public demonstration of what's confusingly referred to as both Hotspot 2.0 and Next Generation Hotspot will be in February: an estimated 75,000 attendees at the next Mobile World Congress in Barcelona will be able to take part."
