Recently, the EU Member States on the use of a Wi-Fi network communication standard for future vehicle plans to vote. 21 EU countries have voted against - which occupy 28
The vast majority of EU member states.
The planned vote, the proposed short-range communication standard car Wifi as a future networking technology, and prohibit the use of 5G cellular network connection. This program is whether the majority of the Member States
Never, in fact paved the way for the EU's future 5G car networking communications standards.
Over the years, the automotive industry in the end to use Wi-Fi or 5G in car networking technology has been divided, General Motors, NXP, Toyota, Volkswagen and Volvo support Wi-Fi
, BMW, Daimler, Ford, Huawei, Intel, Kwai Fong Yun, Qualcomm and Samsung supports 5G.
Whether using Wi-Fi or 5G, V2X (vehicle-to- everything) the basic concept is still the same: cars on the outside world, such as automobiles and other local infrastructure (
Roads, traffic lights, and control systems) to exchange information, coordinate and implement security have full autonomy.
For a long period of time, Wi-Fi camp with low latency, mature technology and so has certain advantages. While the opposite, cellular network technology is behind many. but
This situation will be broken after the popular 5G, 5G only delay is not inferior to Wi-Fi, but also provide more technical advantages.
Generally, Wi-Fi is 802.11p standard for vehicles, which uses a low bandwidth 5.9GHz radio channel, at a distance of 150 to 1 m in the 3-27Mbps
Speed data transmission, the transmission speed of the vehicle up to 260 km / h. Due to a number of practical factors, the actual transmission distance of Wi-Fi and data bandwidth may be in this
Some low-end range values.
The EU offered to Wi-Fi as a major cause of car networking communications technology, it is because Wi-Fi camp believes it has already achieved deployed in 2016, while the 5G is not. although
Wi-Fi standard proposed for many years, but did not develop smoothly, except locally deployed outside Japan, up to now no global commercial system.
But different 5G, currently many countries launched 5G networks, 5G popularity around the corner. Compared to Wi-Fi, 5G can not only provide greater bandwidth and lower upload
Downlink delay, theoretically 5G C-V2X support lossless data transfer between the maximum vehicle speed of 500 km, even more can be done at a distance of 450 meters, but also
Benefit from many of the 5G base station.
Bloomberg reported that, in view of the dominant position and performance of 5G, European companies have recently begun to feel concern about the investment "will be outdated" Wi-Fi technology.
