Transfer Bitrates

Created 20 August 2014

References: Wikipedia. (I know, I know; but this is more of a “quick thumbnail” to help people understand basic speeds of different technologies.

NOTE: Converting “megabits” or “Mbit/sec” to the more useful megabytes is done by dividing by 8.

Wi-Fi (802.11 systems)

802.11a (1999): 3.1~ MB/sec (approx) – significant penetration in the enterprise environment, little in consumer space due to expense.

802.11b (1999): 0.73 to 0.88 MB/sec (approx) – won out in consumer environment over 802.11a since it was much cheaper.

802.11g (2003): 2.75~ MB/sec (approx).

802.11n (2009): 6.75 to 75 MB/sec (depending on mode selected and antenna usage).

802.11ac (2013): 54 to 162.5 MB/sec (depending on antenna connections).

Ethernet

10 (1987): 1.25 MB/sec maximum, 1 MB/sec more likely

100 (1995): 12.5 MB/sec maximum, 10 MB/sec more likely.

1000 (1999): 125 MB/sec maximum, 100 MB/sec more likely.

USB

1.x (1998): 1.5 MB/sec maximum, 1.2 MB/sec more likely.

2.x (2001): 35 MB/sec maximum, 28 MB/sec more likely.

3.0 (2010): 500 MB/sec maximum, 400 MB/sec more likely.

3.1 (2013): 900 MB/sec maximum, 720 MB/sec more likely.
