In fact, much of the 20-25 Mbps (or whatever) pt-to-pt traffic graphs I see often presuppose a certain mix of traffic (e.g. X% http, Y% streaming, Z% ftp, etc). Some tweaks increase latency, but help throughput (and vise versa), so it's always good to know what type of traffic was pushed through the system to generate those numbers. WISPA Wants You!

Speed is by powers of 10 and quantity is by powers of 2. So Mbps is 1,000,000 bits per second, while a megabyte is 1,048,576 bytes.

If we're picking nits, don't forget the fact that most users are more concerned with how fast does my Web page load, so you have to account for wireless (or Ethernet) overhead, IP overhead, and TCP overhead, which can eat up several percent of the link's raw capacity :P Unless you can know in advance exactly what kind of traffic the link will be handling (which is rare but not impossible) it's all guesswork anyway :D David Smith MVN.net WISPA Wants You!

[WISPA] How much data
Ok silly question that has probably been asked a million times. But if a user had a 1M connection how much data in Megs could he transfer if it ran at maximum capacity for 24 hours?

Here is another one (written by a friend of mine) it will calculate the missing value (time, speed, or size) http://therub.org/calc/ another good option is google calc: http://www.google.com/search?hl=enclient=firefox-arls=org.mozilla%3Aen-US%3Aofficialhs=Cd7q=1+Mbps+*+24+hoursbtnG=Search 10.587 GB Ryan* * D.
