The Project focuses on the implementation of the VDL (Very High Frequency Datalink) Mode 2 multi-frequency capability that will enable to optimise the load of the radio frequency channel ensuring the best performance ratio to support the air traffic flows increasing and avoiding frequency congestion.

This project will deploy multi-frequency VDL networks according to ELSA (Enhanced Large Scale ATN deployment) recommendations at country/region level by a group of operational stakeholders and has been divided into two streams: Stream 1 for the upgrade of existing "Model A" networks to "Model B", and Stream 2 for the implementation/upgrade of "'Model C" networks to "Model C with Multi-frequency".

This Implementation Project aims at identifying the deployment activities needed to meet EU (IR) 2015/310 and ELSA' s recommendations, focusing on the envisaged transitional solutions (Model B or Model C with Multi-frequency (MF)). This IP will pay special attention to the recommendations coming from ELSA study, namely, GroundOl - Ground04, Ground06, Ground OS - Ground 11.
