TE Connectivity Trend Paper /// Connectivity for Next-Generation Mobility Page 12 Connectivity for Next-Generation Mobility bandwidth requirements of which EMC performance is a key factor. Therefore, TE Connectivity contin- ues to develop new solutions, push- ing transmission technology ever forward. Our offerings include a differential connector system with a complete shielding interface that will be able to support data rates up to 20Gbps, as well as solutions that use vertical lasers (VCSEL) and multimode glass fiber to achieve speeds of 10Gbps to 20Gbps. 4.4. Wireless Data Connectivity In the same way that connectors and wires exchange information inside the car, antennas connect next-gen- eration vehicles to the outside world, receiving and transmitting data that can be analyzed and acted upon. With its newly acquired antenna technology, TE has more solutions to offer the automotive industry for the V2X communications that will enable fully autonomous driving. 4.4.2 Global Navigation Satellite System A prerequisite for fully automated next-generation vehicles is constant situational awareness, which helps fuel self-driving algorithms. Require- ments for position accuracy have been increasing as OEMs introduce more ADAS features into vehicles. Today, vehicle systems only need to evaluate which lane they are in. In the future, fully automated cars will need to provide positioning awareness down to the centimeter. GPS anten- nas have evolved into GNSS (Global Navigation Satellite System) anten- nas, meaning they are required to receive several positioning systems such as GPS, GLONASS, Beidou, and Galileo. TE is following this trend closely and offers GNSS antennas which provide the high level of position accuracy needed in self-driving cars. 4.4.3 V2X and Cell Fully autonomous cars will need large amounts of information to make the right decisions in traffic. In addition, to sensors that capture environmental data, information will soon be exchanged between cars themselves. The objective is to ex- change information beyond the line of sight that sensors cannot capture. For example, cars will need to com- municate with other cars around a corner. This process will involve V2X technologies that communicate with other vehicles and the road infra- structure. Today there are currently two com- peting standards for the underlying technology: IEEE 802.11p, which is based on the WLAN standard, and C-V2X, which is based on the cellular standard. It remains to be seen which standard will be adopted by the au- tomotive industry. Today, TE offers antennas for both standards and is therefore able to support V2X, inde- pendent of the final standard deci- sion. The cellular network standard LTE is used today to connect cars to the infrastructure or to each other. However, LTE's inherent latency is too high for time-critical applica- tions. 5G, which is currently being specified, will offer low latency and high bandwidth in the cellular world. TE has already developed an early prototype for the 5G antenna. 4.4.4 WLAN and Bluetooth Bluetooth and Wireless LAN (WLAN) also have a place in vehicle networks. Bluetooth is being used for remote access and allows smart phones to communicate with infotainment sys- tems. It will soon replace a key fob, enabling remote locking and unlock- ing. TE has developed integrated Blue- tooth antennas and transceivers in rooftop applications to provide the interface for such use cases. In ad- dition, these solutions can support remote parking applications, where the car is controlled via a smart phone while it 'self-parks.' WLAN is a good choice when high data throughput is required to con- nect consumer devices to the car. Cars already offer WLAN hotspots, which allow passengers to access the internet via a built-in LTE mo- dem. Furthermore, WLAN may be used to connect the car to the Inter- net while it is stored in the garage at home, so that critical software updates can be rolled out overnight via FOTA (Firmware Over the Air) or the driver's music library can be synchronized.
