Thanks, Rich, for reminding us of the vuvuzela from the 2010 World Cup. It doesn't seem prevalent this time. That's a blessing. Maybe the engineers figured out how to block the sound from the broadcast, as mentioned in this story: Buenos notches - the Filter Wizard vs. the vuvuzela
I'm very curious to see what Brazil does with all of this fiber line, antennae, and small cells post-Olympics (not to mention the stadiums). I think the country will need to severly decrease its import tax on foreign phones or increase its manufacturing power to create higher-tier devices.
