AutoUpdater: 56K dialup connection, what normally is the upload speed?

Question

Hi,

I'm building a auto updater and I need to know what kind of upload speeds people get on a 56K modem?

Answer 1

Theoretically 33.6 kbit/s upload = 4.2 kB/s[1].

From own experience, I would say half of that :)

Answer 2

According to Wikipedia, the top (theoretical) speed is 48kbit/s. This is assuming v.92, which a large percentage of users will not have.

Answer 3

About 28.8K I believe (source).

Answer 4

Modems are generally not asymmetrical in their speeds, but I seem to remember that 56k was a special mode and upload was only @ 33k.

Wikipedia states the following in its article about 56k Modems

"The upload speed is 33.6 kbit/s if an analog voiceband modem is used (V.90), or 48.0 kbit/s using a digital modem (V.92)."

Answer 5

From my own experience I'll say about half the download speed. For example I typically see 48k download speed at home and about 24k upload.
