The spectrum allocation for global wireless communications has been redefined or redefined by relevant authorities. From a historical point of view, spectrum allocation has always been dominated by various countries, so it is not consistent in the world, because they are usually controlled by local governments. Unfortunately, the adjustment of spectrum is driven by the economies of scale of the industry, not by foresight in the field or cooperation between relevant institutions around the world. Without spectrum comparison, it is difficult to realize equipment standardization. As the wireless communication industry continues to allocate spectrum, it is foreseeable that different frequency bands will still follow localization requirements in the future instead of being optimized for global needs.
