Almost everyone uses the packet oriented transmission modes of cellular networks. However, unlike TCP/IP, Ethernet and Wifi, not many members of the hacker commnunity are familiar with the actual protocol stack for those services. This talk is aimed to give an in-depth explanation how the lower layer protocols on the air and wired interfaces for packet data services in cellular networks are structured. For 2.5/2.75G, this includes RLC/MAC, NS, BSSGP, LLC, SNDCP, GTP For 3G/3.5G, this includes RRC, RLC, PDCP, NBAP, RANAP
