  This paper presents ideas and concepts for interconnected off-road vehicles,
like harvesters or tandem rollers, which span a mobile network by themselves to
be, to some extent, independent from the network infrastructure. Multiple RATs
are used to cover a variety of use cases, including mmW technology for short
range high bandwidth communication and ranging. The AMMCOA Project aims at
providing connectivity in areas where the infrastructure network is either at
long range distances or out off range entirely. In this case, for certain
network services, like authentication of UEs, to be available, some of the core
network functionalities have to be instantiated locally. This effectively turns
the local network into a light version of a core network. In this paper we give
an overview of the project's use cases, their requirements, the architectural
idea of a local autonomous network (Trust Zone, 5G Island, 5G Private Networks)
and the AMMCOA network architecture envisioned so far.
