LDACS1 vs LDACS2-Difference between LDACS1 and LDACS2
This page on LDACS1 vs LDACS2 describes difference between LDACS1 and LDACS2. LDACS stands for L band Digital Aeronautical Communication System. It is the communication mechanism between ASs (Aircraft Stations) and GS (Ground Station) to provide better Air Traffic Management.
| Specification | LDACS1 | LDACS2 |
|---|---|---|
| Modulation | Broadband system based on OFDM; combining B-AMC and P34 | Narrowband system based on single-carrier technology (GMSK); combining LDL and AMACS |
| Duplexing scheme | FDD | TDD |
| Capacity(Data Rate) | Forward link-291kbps to 1.3MBPS Reverse link-220KBPS to 1.04 MBPS |
270.833 kbit/s per channel |
| Frequency of operation | Operate in 960 to 1164 MHz frequency range | operate in 960-975 MHz frequency range |
| maximum coverage range | 200nm | 200nm |
| Effective RF Channel bandwidth | 498.05 KHz | 200 kHz for a single channel |
| Frame Structure | Refer LDACS1 frame structure | Refer LDACS2 frame structure |
| Physical Layer | Refer LDACS1 physical layer | Refer LDACS2 physical layer |
To understand difference between LDACS1 and LDACS2 one need to understand physical layer and frame structure of these systems as mentioned below.
