First, I will say the current state about mmW.
In the field of mmW, the United States developed very early, especially in the term of Satellite Communication. So He has accumulated too much knowledge and technologies about the Ka-band. His Ka-band satellite communication verticals are very mature. Many important materials, components and technologies in this field are developed by military institutes many years ago and put into engineering, such as Ka-band RFIC, Ka-band TR Component, Ka-band Wire, Ka-band amplifier, Ka-band receiver, Ka-band connector, Ka-band antenna, Ka-band phased array and Ka-band Instrument, as well as the application system and experience. Many of them are also prohibited to output China. Japan is so.
Also, there are many military companies in USA developing the equipments with relation to base station in 4G and 5G.
I want to say, if we also select the mmW as the main direction of 5G, we have not much too edge because we will depend on US more than before in the term of hardware.
Maybe I am wrong..... |
