In the second version of our LDACS IETF document, we explain characteristics of LDACS in even greater detail, explain the LDACS Sub-Network concept, give details on the Medium Access (MAC), mobility and LDACS incremental deployment concept (chapter 5). Protocol stack and services of each protocol layer are presented in a more precise way (chapter 6) than in the previous version.

This is the first draft for the LDACS IETF project. Here we reduce the official LDACS specification to the important details for the IETF and its relevance for RAW. We explain the motivation of digital aeronautical datalinks (chapter 3), present the characteristics of LDACS (chapter 5), the architecture of the LDACS protocol stack (chapter 6) and gibe an overview of foreseen security features of LDACS (chapter 7).
