28 /* GSMTAP is a generic header format for GSM protocol captures,
29 * it uses the IANA-assigned UDP port number 4729 and carries
30 * payload in various formats of GSM interfaces such as Um MAC
31 * blocks or Um bursts.
32 *
33 * Example programs generating GSMTAP data are airprobe
34 * (http://airprobe.org/) or OsmocomBB (http://bb.osmocom.org/)
35 *
36 * It has also been used for Tetra by the OsmocomTETRA project.
37 * (http://tetra.osmocom.org/)
38 *
39 * GSMTAP also carries payload in various formats of WiMAX interfaces.
40 * It uses the wimax plugin to decode the WiMAX bursts.
