The era of unification of Internet of vehicles is coming!

According to foreign media reports, recently,The Federal Communications Commission (FCC) officially voted to allocate the 5.9 GHz band (5.850-5.925ghz) to Wi Fi and c-v2x.

According to the newly approved frequency division plan, the lower 45mhz spectrum in the frequency band will be allocated to Wi Fi unlicensed equipment, and the higher 30MHz spectrum will be allocated to c-v2x technology to improve vehicle safety.

This marks that the United States officially announced to abandon the DSRC standard for Internet of vehicles and turn to c-v2x.After the U.S. shift, it means that c-v2x, which is mainly promoted by China, will become a widely recognized industry de facto standard in the world.

Notably, more than 20 years ago, GHz 5.9 was designated for another automotive communications technology

However, with the rapid growth of the demand for Wi Fi spectrum, the progress of DSRC technology is very little.

The FCC Chairman Ajit Pai at the voting meeting that:

Compared with DSRC, China's c-v2x has many advantages,such as supporting longer communication distances, better non-horizon performance, stronger reliability, higher capacity, and better congestion control.

In addition, c-v2x is based on cellular network, which can be reused with current 4G and 5g networks, with wide network coverage and low deployment cost.On the contrary, the DSRC technology based on 802.11p needs to build a large number of RSUs in the network, and the deployment cost is high.
