Web21 apr. 2015 · Today, the average download speed is 35Mbps, while the final iteration of modem technology supported transfer speeds of 56Kbps. That makes today's networks about 625 times faster than the old modem connections. Yet modem technology itself came a long way; those 56Kbps modems are more than 500 times faster than their early … WebFrom 1960 to 1980 most modems only had a speed of 300 bps (which was also 300 baud). This is only 0.3kbps. Modern modems are over 100 times faster. Some old-slow modems are still in use so they are not really "antique" quite yet. 29.4 Proprietary protocols, etc. These did not conform to the ITU V-series standards.
