If by Mesh Network you mean Meshtastic, they have very different use-cases.
Meshtastic is requires regular nodes/repeaters within its somewhat smaller effective range to be effective (putting repeater stations atop hills or mountains can drastically extend that effective range), it also exclusively operates via text, not audio.
NVIS is just a small long-range portable radio that bounces radio waves directly off the ionosphere which is reflected in a circular radius from the antenna of 150 to 300 miles, and is not reliant on being atop mountains to attain that range due to the reflected bouncing. The video gives details on how it is generally used.
