Up until the last four or five games of the 2007/08 promotion season we where only getting about 17,000. I've never had any problems with the scanning my season pass.
The new card system is better quicker and easier. My turnstile has been a lot faster this season in the absence of people trying to find the right number and holding everything up. 100mbps is far more than enough for everyone in the stadium to scan their ticket at the same time as Mel U says. The data being transferred to say the tickets been used will be bytes, not even kilobytes. A 100mbps line would be enough for 10 million people to scan their tickets simultaneously and be accepted instantly. If it runs slow I'd bet my anal virginity that the line won't be holding it up. No most people don't have at least 300mbps, most people have somewhere between 10-50. To put into perspective my home line is 16mbps and gets download speeds usually around 1mbps but sometimes up to 2, it can download a full 1080p movie in around half an hour/hour. A 100mbps line is over 6x faster so could do a full 1080p movie in 5-10 minutes, there's no way it will get held up transferring a data file that is probably as small and simple as just a few letters/numbers, even if everyone decided to do it at once.
You're on about your internet connection now. Most people have networks within their home of 300Mbps. As in between all your devices and your router, that's what standard network cables and routers generally support. I don't know where you got the number 16-50 from by the way. If you're talking about ADSL rather than fibre-optic it's anywhere up to 24Mbps, never above that unless you've got a fibre line. Furthermore, 100Mbps is not the same as 100MBps. The second one with a capital B is Megabytes p/s. The one we're talking about at the KC (and in your own internet connection) is Megabits p/s. A megabit is an eighth of a megabyte so it's 8 times slower than you think so remember that if you want to do the maths like Mel did. And lastly, in terms of working out how much the data is delayed by simultaneous swiping of cards you'd need to know how much cabling there actually is. If all the turnstiles are linked to separate cables which join up as one before they reach the control centre thing then the overall speed of that cable restricts everything and if its 100Mbps that isn't brilliant. However if they each have a separate cable all the way to the control centre then they won't delay each other at all and it shouldn't be a big problem.
The problem with the card system is still having useless turnstile operators who take your card off you then cannot actually use the system themselves. This results in them giving me my pass back for me to scan the card myself ("which is what I wanted to do before you took my card off me!")
I was comparing to explain, the system at the kc is probably a LAN connection which is virtually the same as Internet. If its getting held up anywhere from technical issues it will be the server processing it on the other end. 100 megabits/second is still way more than enough for each turnstile to be used at the same time. And don't know about you in the big city but round here the fibre lines are limited somewhat if they run that fast, definitely not 300mbps. Don't know for sure though til they install it I'm in a brand new housing development and on a copper wire at the minute.
You're still misunderstanding me when I talk about 300Mbps. That's the speed the router communicates with your devices. I'm not talking about anything going outside your house at all. Fibre connections are jolly fast, they can go up to 3 or 4 hundred and even 1Gbps in some situations. However the household ones being rolled out now are limited to 100Mbps because no one needs more than that yet and it makes it future-proof for the ISPs to easily raise everyone's speeds again in a few years' time. That applies to BT and KC. LAN isn't the same as internet. LAN is what you have in your own home and it's much faster than an internet connection; that's what I'm saying is usually around 300Mbps. I don't know whether the cabling at 100Mbps would slow it down and cause a problem but it certainly surprises me that it's that slow because most people have faster than that in a home LAN.
LAN is practically the same, it's the same sort of wiring, they key difference being LAN is a direct connection that runs as fast as the cable can handle (or the ports on either device) where as Internet depends on the signal coming from the exchange or ISP, which is obviously a lot lot slower than LAN.
