File sizes and download speeds of 56k, 3G, 4G, and High speed wireless internet

Here is a chart I made comparing speeds of various internet connections and showing how fast/slow one would expect their files to download. Remember that these are really hypothetical and depend so much on where you are, what kind of device you have, etc. You should also remember that equipment you are using should be regularly maintained (visit BoostPoorSignal.com for more info). Theoretically 4G and high speed internet should be nearly the same but realistically this is not the case. So please do not take these as fact, rather, use this chart as a guide to consider when developing for both web and mobile devices.

100kb 250kb 500kb 1mb 1gb
56k Modem 15 seconds 36 seconds 1 minute 2.5 minutes 1 day 18 hours
3G <1 second 6 seconds 12 seconds 25 seconds 7 hours
High Speed/Wireless/4G <1 second 1 second 3 seconds 5 seconds 1.5 hours

*note – these speeds assume best case scenario. More than likely all speeds will be
Slower. Both 3G and 4G speeds will probably be significantly slower, especially as 4G max.

Your PC behaving strangely? Is it very slow? Does it crash very often? Doesn’t it boot at all? Well, these are common problems, that everybody have met in their life – to be honest, I’ve got these problems several times – and this comes from several reasons, but the first is: tech devices ages very fast. Xtra-PC is a small USB device that you plug into an old, slow or dead computer (Windows or Mac) to give it new life. Basically, it’s a custom operating system, based on the proven foundation of Linux, that runs directly from the Xtra-PC USB device, and it even works on computers with a missing or crashed hard drive.

Speeds are not even available yet.
