Cellular V2X

The Cellular V2X (C-V2X) is an IEEE standard describing a technology to achieve the V2X requirements. C-V2X is an alternative to V2V communications[1].

History

Cellular V2X was developed within the 3rd Generation Partnership Project (3GPP)[1], to replace the US promoted Dedicated short-range communications (DSRC) and the Europe originated Cooperative Intelligent Transport Systems (C-ITS) As such standards are decisive steps towards the target autonomous driving[2] and clues to market influence, especially as the National Highway Traffic Safety Administration (NHTSA) plans to propose the compulsory introduction of Vehicle-to-everything technology off 2020 for all US vehicles.

Modes

The modes, Cellular V2X may be implemented, are:

Device-to-network i.e. Vehicle-to-Network (V2N) communication using the conventional cellular links to enable cloud services to be part of the end-to-end solution.

Device-to-device, which includes Vehicle-to-vehicle (V2V) [3], Vehicle-to road and infrastructure (V2I) [3] also including the use with toll systems and the direct communication and Vehicle-to-pedestrian (V2P) – also without use of network involvement for scheduling – for the protection of the most vulnerable road users, the pedestrians[4].

Problems

All the communications systems based on wireless communication suffer from the drawbacks, inherent to |wireless communication, which are the limited capacities in various areas:

  • Limited data rates[6], considering, that just one autonomous car will use 4,000 GB of data per day.
  • The fact, that wireless communication is prone to external influences, which may be hostile[7]
  • In metropolitan areas, limits of data propagation due to surroundings such as buildings, tunnels[8] and also Doppler effects, causing propagation speed reduction by repetitive transmissions required.
  • The costs to provide a comprehensive appropriate network such as LTE or 5G are enormous [9].

Outlook

The solution to handle the flow of data is expected to come from artificial intelligence[10][11]. Doubts in artificial intelligence (AI) and decision making by AI exist[12].
