Huawei's 5G technology has achieved great success in communication. 5G is 20 times faster than 4G in signal transmission speed. However, the 5G signal is still transmitted using needle antenna, so the transmitted signal is the same as the past radio signal, and it is still not accurate enough to be used for traffic target positioning.
Now, in military, phased array antenna has been widely used, so the positioning of traffic targets is much more accurate than before. Therefore, using 5G technology of phased array antenna to transmit signals will be faster and more accurate.
