If you are in the business of maritime services, such as engine/equipment maintenance or weather forecasting, you are often challenged by connectivity problems when ships are crossing an ocean or sailing along remote coastlines.
VDES, the extension of AIS, can be seen as a maritime internet-of-things (IoT) technology which is both very cheap and extremely secure. VDES adds real data channels to AIS and it combines coastal VHF radio and satellite connectivity into one global system working over the VHF antenna. This means that service providers can easily push information to ships or retrieve data from ships anywhere in the world.
