D he traffic with Autonomous cars in networked cities, in which traffic lights and parking spaces are also intelligently controlled, relies primarily on smooth digital communication.
The availability of a comprehensive broadband communication network is essential. The current 4G cellular standard is not sufficient due to the amount of data and the required transmission speed.
Data transmission with up to 10 Gbit /s
The example value for the download rate illustrates this. While with 4G ( LTE) up to 300 Mbit or with LTE + up to 4 Gbit per second and thus significantly more than can be achieved with most landline internet connections, with 5G it is already 10 Gbit. However, it will take a few years before the 5G network is set up. A nationwide coverage is unlikely to be guaranteed, even with 4G there are currently still large gaps in nationwide coverage.
In addition to mobile communications, other communication options between cars and the Internet of Things should also be used in smart cities will. V2X is the technical term, vehicle-to-everything. With WLAN and WLANp, the traffic light switching can be controlled at intersections depending on the traffic situation and pedestrian volume, with passers-by movement and presence data is also recorded anonymously via the 4G network or NFC (Near Field Communication) CES 2019
The automotive supplier Continental will present a global 5G hybrid V2X network at the CES (Consumer Electronics Show, January 8-11, 2019) in Las Vegas. This should enable communication between the individual traffic modules at various levels and be combined in a data package for the software in the vehicle or in a traffic control center.
While V2X systems work over short distances, the combination with 4G and 5G, a flow of information over longer distances can also be added. The end of a traffic jam is not only announced to reduce speed, vehicles further away can start planning the bypass route straight away. According to the company, an unnamed customer, presumably a Chinese automaker, has already awarded a 5G hybrid V2X order to Continental.
The contract for a first 5G project based on our hybrid V2X platform is one not only for us, but for the entire industrygreat news. The fact that 5G appears so early on the development roadmap clearly shows that the automotive industry has its finger on the pulse of digitization, 'says Johan Hiebl, head of the Body & Security and Infotainment & Connectivity business unit at Continental.
