Road telecommunications system

1 . A road telecommunications system, comprising:

a plurality of wireless access stations distributed along a plurality of road segments that make up a road path, the access stations comprising:

first communication modules, configured for wireless communication with user mobile devices, on board of vehicles travelling along the road path and located within respective first coverage areas, and

second communication modules, configured for wireless communication with vehicular communication modules, integrated in vehicles travelling along the road path and located within respective second coverage areas,

wherein, for each road segment, the arrangement of the respective first and second communication modules is such that the respective first coverage areas, adjacent to each other, entirely cover the road segment, and the respective second coverage areas, adjacent to each other, entirely cover the road segment,

a local control centre for each road segment, each local control centre comprising at least one local server system, in wired signal communication with the first and second communication modules of the access stations distributed along the respective road segment, so as to exchange data with the user mobile devices and vehicular communication modules via the first and second communication modules,

wherein, the system comprises a wired segment data network for each road segment connecting the local server system of the local control centre of the respective road segment to the first and second communication modules of the access stations distributed along the respective road segment,

a wired data backbone connecting the local server systems of all the local control centres to each other and to the central server system,

a remote control centre, comprising at least one central server system in wired signal communication with the local server systems of all the local control centres, the central server system being configured to monitor an operating state of the local server systems,

wherein each segment data network forms one or more connection loops, such that each access station is connected to the local server system of the local control centre of the respective road segment via at least two independent data connection lines, and

the data backbone forms one or more connection loops, so that each local server system is connected to the central server system via at least two independent data connection lines.

2 . The system according to claim 1 , wherein the first communication modules are configured for wireless communication with user mobile devices, which are mobile computers of which at least one is selected from a mobile phone, a palmtop, a smartphone, a tablet, a smart watch and smart glasses.

3 . The system according to claim 1 , wherein:

the first communication modules are configured to provide, to the user mobile devices, access to an Intranet of road services, preferably via Wi-Fi in Motion technology,

the second communication modules are configured to exchange semi-autonomous or autonomous driving data with the vehicle communication modules, preferably via dedicated short-range communication (DSRC), or Cellular-Vehicle to Everything (C-V2X) technology.

4 . The system according to claim 1 , wherein each local server system is configured to:

receive from the first communication modules wireless signal power values exchanged with the user mobile devices, and

select and dynamically change according to said signal power values, for each user mobile device, first communication modules, one at a time, as access points to establish a Wi-Fi connection.

5 . The system according to claim 1 , wherein each local server system is configured to locate the user mobile devices along the respective road segment.

6 . The system according to claim 1 ,

wherein the

wired segment data network and the wired data backbone are made of optical fibre.

7 . The system according to claim 1 , wherein:

each local control centre comprises an electrical delivery point for connection to an electrical distribution network, and one or more electric power generators, preferably including at least one engine-generator set and a renewable source-based plant,

the system comprises a wired segment power network for each road segment, each segment power network connecting the delivery point, and each generator of the local control centre of the respective road segment, to the access stations distributed along the respective road segment, so as to power supply the access stations.

8 . The system according to claim 1 , wherein:

each local server system is configured for stand-alone operation when disconnected from the central server system, and

each access station is configured for wireless communication with at least one adjacent access station in the event of an interruption of the wired connection to the local server system of the respective local control centre.

9 . The system according to claim 1 , wherein each local control centre comprises two local routers in redundant operation, each configured to connect the respective local server system with the first and second communication modules of the access stations distributed along the respective road segment.

10 . The system according to claim 1 , wherein the access stations comprise cameras configured to identify vehicles on the road path.
