Next Generation Air-toGround VHF Communications

N ext Generation Air-to-Ground VHF Communications provides for the replacement of the existing analog radios used in the National Airspace System (NAS) with new state-of-the-art digital radios. These digital radios employ a TDMA (Time Division Multiple Access) MAC (Media Access Control) capable of multiplexing both voice and data on the same channel.

BCI supported the NEXCOM program through SARPs validation and a testbed development effort. BCI is currently supporting efforts aimed at the upcoming NEXCOM Demonstration/Validation (DEMVAL). BCI is developing software for the ground infrastructure to be used in the DEMVAL.
