LTE support for the connected car

3GPP launches a new Study Item on “V2x” to address the use of LTE to ensure connectivity between vehicles, roadside infrastructure and the people inside and around connected vehicles.

3GPP has launched a new Study Item on “V2x” to address the use of LTE mobile networks to ensure connectivity between vehicles, roadside infrastructure and the people inside and around the connected car. The Study Item will particularly consider the usefulness of new LTE features to the automotive industry – including Proximity Service (ProSe) and LTE-based broadcast services such as Public Warning Systems (PWS) and eMBMS. It is expected the Study Item will lead to the publication of a “Study on service aspects for LTE-based V2X” by the end of 2015. The 3GPP Service and System Aspects Group has also issued liaison statements to other interested parties about the start of work in the following areas:

  • V2V: covering LTE-based communication between vehicles.
  • V2P: covering LTE-based communication between a vehicle and a device carried by an individual (e.g. handheld terminal carried by a pedestrian, cyclist, driver or passenger).
  • V2I: covering LTE-based communication between a vehicle and a roadside unit. A roadside unit (RSU) is a transportation infrastructure entity (e.g. an entity transmitting speed notifications).

The 3GPP Study Item proposes to document these V2X use cases and to assess how LTE can meet the needs of service providers, the automotive industry, drivers-passengers-pedestrians and the roadway authorities.
