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.

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

And it's not the first time the World Cup created technology challenges:

Audio awareness - a winner at the 2010 FIFA World Cup

Buenos notches - the Filter Wizard vs. the vuvuzela

Interesting portrait of how hosting a big sports competition can push a country forward.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
