2 Papers for WG B 18TH Meeting, 17-25 February 2005 Bangkok, Thailand Working Paper 9, Report of VDL Mode 3 Voice Quality Tests With Radio Interference, by Yasuyoshi Nakatani, Japan
3 VDL Frequency Planning WGB/17 completed the frequency assignment planning material, including relevant guidance material, for VHF digital link (VDL) Modes 2VDL Mode 3 could operate on the fourth adjacent 25 kHz channel from a DSB-AM assignment and on the second adjacent 25 kHz channel from a VDL Mode 3 assignment.Test planning for VDL Mode 4, including the need for an assignment in the MHz band is on-going.Excerpt From ACP-Memo/02, 14/01/05, from ACP Secretary to Members, Aeronautical Communications Panel (ACP)

6 Status Frequency Planning Criteria VDL Mode 4 Test Plan Presented to WG BTesting according to the test plan is planned for early next year.Reference: ACP (WG B), 17th Meeting, 20 – 25th of October 2004, Montreal, Canada Signalling Channels for VDL Mode 4, F. Lindblom, Swedish CAA, Sweden
7 VDL Band implementation target plan agreed by the EANPG FMG. Reference: ACP (WG B), 17th Meeting, 20 – 25th of October 2004, Montreal, Canada Signalling Channels for VDL Mode 4, F. Lindblom, Swedish CAA, Sweden
8 Future Work VDL Mode 4 Global Signaling Channel Further work was needed to complete the the work on Frequency Planning Criteria.VDL Mode 3 to VDL Mode 2VDL Mode 4 to VDL Mode 2Guidance material on 8.33 kHz and 50 kHz radios.There are currently no plans to provide further guidance material on 50 kHz radios, unless required.Note: 1.
