Technical Summary
This document provides an overview of the architecture of the L-band Digital Aeronautical Communications System (LDACS), which is a wireless communication standard defined outside of the IETF and relevant to the work at the RAW WG. LDACS provides a secure, scalable and spectrum efficient terrestrial data link for civil aviation, based on a scheduled, reliable multi-application cellular broadband system with support for IPv6.
It is expected to become a data link of choice for IP network-based aircraft guidance for which the RAW properties of high reliability and availability are essential.
Working Group Summary
The process was as smooth as possible, with no contradiction over the mailing list or during meetings. The document is really the description by matter specialists of an externally-defined link-layer. It is a useful base for the RAW work and good information for the rest of us.
Document Quality
LDACS is an emerging technology; prototypes were presented, see https://ieeexplore.ieee.org/document/9397802. The draft was written by the technology specialists. It is very readable and quite thorough.
