I saw an ad on TV showing Comcast's speeds. They showed 3 people downloading a 2 GB file on a tablet at once. It finished in seconds. I don't know if I did it right, but if they somehow had a gigabit connection, it would take 16 seconds to download the 2 GB file. On the other hand, they were using tablets with three people downloading at once. Which at best would give them a max link rate of 433 or 866 if they were using AC as the best case scenario.
The best base scenario for 3x3 AC devices are speeds of about 380ish Mbps. Considering it was only 2x2(not sure if they have 2x2 AC in tablets yet, or just 1x1), they top out at 280-300 Mbps at best right next to it. Which in other terms, it would take them at best maybe probably at least 50 seconds to download it as a best case scenario. Yet, they download it in like 3-4 seconds lol.
They were doing the whole invite people on camera thing to show them the speed of Comcast's internet. Since when did Comcast offer over 3 Gbps or higher to customers and have some sort of 24 stream AC gateway and 8 stream AC tablet?
My calculations are probably all messed up lol. But I assume you get the point. It's falsely showing speeds and the devices are probably running some type of program that just emulates a fake download to make people believe it's actually downloading 2 GB in seconds lol.
