COMMET is a Spanish funded project which focuses on the development of an improved railway communication system by means of 5G technologies.

The goal of the present project is to address an deal with one of the main limitations of the current broadband connectivity in high mobility proposed by 5G, which in fact is not tailored to transport scenarios with high density of vehicles and high speed.
To deal with these topics, a novel integral architecture to manage the connectivity in mobile 5G scenarios is proposed. This architecture is based on a mobile network solution that uses novel Relay Nodes, consisting of transceivers that work simultaneously in the LTE and millimetre bands and with the management of the radio resources through Virtualised and Software Defined Radio Access networks. The proposal also includes the integration and management of communications associated with services related to operations and safety in transport, mainly in the railway environment.
