## Detailed Description

gsmtap header, pseudo-header in front of the actua GSM payload.

GSMTAP is a generic header format for GSM protocol captures, it uses the IANA-assigned UDP port number 4729 and carries payload in various formats of GSM interfaces such as Um MAC blocks or Um bursts.

Example programs generating GSMTAP data are airprobe (http://airprobe.org/) or OsmocomBB (http://bb.osmocom.org/)
