This analysis illustrates the total global bandwidth and data storage needs for a given quantitiy of aircraft that might be in flight simultaneously

b) 64wps flight data recorder (black box) data which was the standard recording rate for many aircraft in the late 1980s and early 1990s

These bandwidth needs assume continuous transmission and not transmission of an accumulated amount of flight recording.
Total Global Bandwidth Required (Mbps) for 64wps data frame
Black Box Data Recording Rate = 1024 ARINC 717 words per second (wps) (New aircraft are increasingly using this data rate)

a) 1024wps flight data recorder (black box) data which is the most common recording rate on new aircraft in 2015
This rate would be 16x less if only 64wps data is sent (768 bps); or 170x less if only lat/long/alt is sent (72 bps).

Transmission rate to send 5.4 MB / Hour continuously without including overhead = 12.3 Kbps
