Have seen some USB modems online with 56k connection. Does anyone make them with higher speeds How would current browsers handle such connection speeds

56k is the maximum theoretical speed achievable on a phone line through its 4kHz audio bandwidth. Actual connection speeds not counting compression are usually 48kbps since the performance ceiling is capped off by transmission power limits.

Higher speeds on dial-up are not possible due to the way the dial-up system works: your phone line is sampled and converted into 8bits 8000 samples/second PCM audio and routed over the switched telephone network... so your audio signal itself is crammed in a 64kbps bitstream.

I don't think that they can make it any higher coz I believe that its at its limit. if a broadband connection is not an option for you, I'm afraid your stuck with that speed.
