    There are 884 APs, not 84 as the summary claims.

    84 APs would be pitiful. Cisco recommends no more than 35 users per AP radio. You can probably push that up to 50 for public access WiFi, maybe - if you're thin stretched - a little bit more as long as many clients are 5GHz devices. Given that many APs will be back of the house and not accessible to the public you wouldn't be able to serve more than one to two thousand users on 84.

    • Honestly 84 would most likely be enough for the superbowl, sure there are thousands of people there. But probably less then 1,000 of them 1. are geeky enough to want to be on their laptops at the superbowl. 2. Think it's a good idea to even bring a laptop into a heavily crowded chaotic area filled with screaming crazy people holding beverages, and who knows how many thieves wanting to take advantage of the situation. Sure smart phone usage is way up, but considering most all of them have a data plan anyway

        If you read the article, "ATT WiFi is everywhere in the building". That is referring to ATT augmenting their 3G network via WiFi. All their WiFi enabled smart phones look for an SSID named attwifi. The layer three gateway of that network triggers the phones to submit their phone number to that gateway, which looks it up in the ATT subscriber database and grants access if you have a data contract with them. That alone will account for many, many thousands of users. Doing that is significantly cheaper for ATT

          Wait, so if I just set my SSID to "attwifi" and mess around with some no-op challenge/response stuff when phones connect, I can pretend to be an official AP for AT&T cell phones? I sure hope all of the data flowing over that network is encrypted...

          • by zn0k (1082797)

            Don't know how hard it is to become a gateway. But it's distributed via unencrypted, public WiFi. The SSID is active at any Starbucks - go to one for a half hour and play with a packet sniffer.

          They're at the Superbowl. The fucking SUPERBOWL. Have they nothing more important to do than fuck with their iPhones, wait in huge lines for bad and expensive food, and then wait in huger lines to recycle the food, while wasting similarly huge amounts of time shuffling to and from their designated seat?

            In my experience, you might go for food/restroom breaks ONCE throughout the 3.5-4 hours you're there. That doesn't seem unreasonable to me. And usually you do it during one of the breaks in the game. Last game I was at that's exactly what happened - at halftime, we went to the restroom and grabbed some food. The rest of the time we were in our seats watching the game.

        I think you're underestimating smart phone saturation. My wife and I go to hockey games at Verizon Center in DC, and we both have iPhones (and yes I am aware of the irony of using an AT&T phone in a place named "Verizon Center"). Before this season, the 3G network was basically unusable between the periods, and not very good the rest of the time. This year, the arena installed free Wifi for attendees, and that, while cool, is still pretty limited - we usually can't connect to either network they set

          Most of the data is probably video. They have a gazillion cameras, recording in HD and 3D, and they may well need to store it raw/uncompressed, compressed, before and after editing. I do not have any intuition about how much space one game's video might take up, but they probably have seasons-worth of footage stored there, probably from thousands of games where commentators might refer during play.

      • Same network, not the same network.It depends on how you define "network".

        40,000 ports, PLUS 884 Access points each capable of 20-50 connections each all on the same configurable network infrastructure = one network. OR you can look at collision(broadcast) domains and understand that 40,000 connections alone would be impossible, and realize that they use VLANS and other routing protocols to segment the collision domains logically (routing, security, public, private, command/control etc).

    One thing I found interesting is that the Cleveland Indians are a big user of storage. When the player is in the hole (second next to bat) they can bring up any and every pitch they have ever received from the current pitcher and likely relievers. That means the metadata has to be fast enough to find the pitches and then the streaming media server has to be able to serve it up basically instantly if they want to view a couple of different at bats in the time they are in the hole, pretty cool IMHO.
    • by swb (14022)

      There was an article in the NY Times about Major League Baseball doing this for EVERY CAMERA ANGLE for EVERY PLAY, with full metadata for everything happening, including what crazy shit people write on signs.

      Apparently it was all in queryable database so that you could find out, say, what happened when Batter X faced Pitcher Y on Team Z in Stadium 2.

      I have a friend who runs the booth equipment that does titles on sports events, with the NFL games being the biggest gig.
      The thing that strikes me about it is how low-tech the process really is. The stats data is available for pretty much the entire history of the league, and they can pull up whatever they want, but beyond that it's really simple, a director says what they want in the headset and the operator looks it up, and it gets displayed in whatever format was defined in the couple of hours they have

    A friend of mine from high school was a sociology major at Tulane. However, he did work in the computer labs as his work-study job. Senior year rolls around, and the Super Bowl comes to New Orleans. The NFL asked the Tulane computer labs for a few student assistants who they could hire to help out. He ends up impressing the guys enough that they offer him a job doing some basic IT work for them - at NFL headquarters in Manhattan.

    He ended up parlaying that into a job with the WHO, and then moved to Geneva, where he's been ever since. Probably the most successful sociology grad they've had in a long time.

    I, for one, would love to see the UI that the techs use to run the queries on obscure NFL statistics during games.

    "This is only the second time 3 consecutive 3rd down conversions have occurred between 11-3 rated AFC teams in outdoor stadiums with 2nd string quarterbacks using a QB option play"

    And they are able to run these queries quickly...usually within the time of the next play. How do they do that? Is it raw TSQL styled queries or do they have some kind of UI for that?

    • by Metrathon (311607)

      I have wondered about that too. The way I would do it would be to have a number of canned queries that become relevant as the game progresses, each able to flag itself if something "unusual" should occur. Surely they are able to query on the spot but there has to be a somewhat large pool of "interesting" things preprogrammed - just waiting to happen.

    • by drinkypoo (153816)

      I'll bet you money that the system just spits out stats like that for the benefit of the announcers. I'm sure they have one or more people doing realtime reporting as well. If the database is put together worth a damn then the queries won't even take long.

    • I have no doubt in my mind that there are staticians conjuring up stats for the announcers to talk about. My question is, do they have specific staticians that they work with? Like a good producer or something like that. Like do they announcers just use the local stadiums guy, or do they bring in there man that they know can kick out the craziest stats?

        True. I'm not an expert in how the HD cameras transfer the data to the storage but I'd imagine its done somewhat cheaply with COTS equipment. Streaming raw HD video is heavy duty but I'd be surprised if those cameras don't put it in a much more efficient format.

        1080p H.264 only needs a 20mbit pipe to stream right?

          That was my thought. If the NIC is the limiting factor (likely if you are streaming video) then there is no need for faster, hotter, less efficient hard drives (which is very similar to the Cobra vs Camry comparison:).

Most likely the camera's are connected with at least a gigabit connection for the low res and FibreChannel, 10GbE or some proprietary link for the rest and there are a LOT of camera's. To stream random input like that at a 2K uncompressed already exceeds 1 Gbps per stream and then you have the database, statistics crunching, parity or mirroring overhead, disk failures and repairs etc. etc. Your 50 SATA hard drives are not going to pull that.

Nothing illegal about driving down the street backwards, e-brake u-turns are another, which requires a little skill to not look "reckless" , just a little break in u-turn can save you the extry 2 points in the in the 3-point turn.
