Brazil World Cup Stadiums to offer 50 Gbps fibre networks
Friday 03 May 2013 09:13:29 by Andrew Ferguson

People are used to using WiFi hotspots and getting speeds that are acceptable but nothing to be proud of, and there is a chance that with each of the 12 stadiums that will host the 2014 World Cup in Brazil having two 50 Gbps connections people will be able to share all their amazing thoughts on the matches.

While access to two 50 Gbps connections sounds incredible, if you consider that a stadium may hold 100,000 people, this actually works out at 50 Kbps each, assuming one of the links is reserved for official media use. So still will rely on not everyone trying to upload their photos of an amazing goal to the Internet at the same instant.

The Brazilian Communications Minister Paulo Bernardo makes a very sensible point, that fans attending the tournament next year may want to buy a local sim for their phone to avoid excessive roaming fees, and also that Brazil uses 2.5GHz for its newly launched 4G service. Brazil will in time move to what is going to be become a standard frequency for 4G which is 700MHz but this requires the transition to digital TV broadcasts to complete, in the UK while we are fully digital for TV now, the digital TV still occupies the 700MHz band and is not likely to be moved until 2018.

If I was at a World Cup final in Brazil - there is no way I'd be worrying about net access. I'd be drinking and partying.

Short of putting a cell in every few seats of every stand 50Gbps isn't going to be stressed.

What did London have?

50Gbps = 5 x 10^10 bps
100,000 people = 10^5 people
5 x 10^10 / 10^5 = 5 x 10^5 = 500kbps per person
Ten times faster through the power of O-level Maths?

The London Olympic Park had, apparently, WiFi infrastructure that totalled just under 2Gbps capacity.

That was 1500 separate WiFi access points.

The limiting factor in Brazil isn't going to be the speed of the fibre, but the number of access points.

I was in the technology section of the Royal Artillery Barracks. The site was fed with multiple fibre connections, as were all sites, but that was mostly for robustness/backup purposes, rather than capacity. I'm not sure it was close to 50Gbps though.

Yes, the media parts had their own capacity. As did the behind-the-scenes staff. Add in the backhaul for the additional 2G and 3G services, plus Airwave for on-site radios. And probably more for the additional radios for police and other emergency services.

The fibre has to support a lot more than just the crowds...
