Cellular protocol stacks for Internet
GPRS, EDGE, UMTS, HSPA demystified
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.
