LDACS is a wideband terrestrial system with line-of-sight coverage intended to work along VDL2 for new and more demanding services. It operates in the L-band (around 1 GHz), which has excellent propagation characteristics. The operational compatibility (spectrum interference) with existing L-band systems (Navigation DME, GNSS, Military JTIDS/LINK16, mobile telephony) remains an important subject, and desirable technology features were identified that could make LDACS spectrally compatible.
