What 56k Connect Rate Should You Expect?
56k Modems rarely connect close to 56k. In the US, FCC-imposed power give most 56k modems a maximum potential for a 53.3k connection.
But, what happens in the real world? These are my estimates of 56k connections. You can see actual results from thousands of entries in Modemsite's 56k Modem Survey section.
|About 60-70% of 56k modem owners are getting 56k connects (rates higher than 33.6k). 30-40% get rates of 33.6k or less.|
|Of those getting 56k rates, 80-90% are getting 40k or higher. About 75% get rates between 44-49.3k. About 10% get rates of 50k or higher, and about 15% get rates between 34.6 - 38.6k. However, the throughput achieved by a substantial portion of the connections doesn't match the connect rate.|
|Of the 30-40% of 56k modem owners not getting 56k connects, about 15% are connecting at 31.6 - 33.6k, 70% at 26.4-28.8k, and 15% at 24k or lower.|
The rate achieved depends upon a number of factors including:
The Modem (sometimes the one you have won't work with your line conditions/ISP)
The Modem Firmware/driver (sometimes a firmware upgrade/downgrade will yield improvement)
Your line conditions (sometimes the facilities provided by the phone company prevent 56k connects)
The ISP's Modems (sometimes your modem won't achieve 56k-interoperability with your ISP's 56k modems)
The ISP's Modem Firmware (sometimes an ISP modem firmware upgrade will yield improvement)
