I have yet to receive a good answer to the question of why regulators require specific spectrum bands to be used for specific modes of “last mile” technologies. The most persuasive reasons have been tied to revenue maximization for government. The technical reasons are not very persuasive. It appears the Myanmar government is going to make USD 80 million x 3 (or 4) by giving this authorization. But anyway, it is good that 4G is being rolled out in this country where most phones are smartphones and are thus likely to be able to use 4G with just a change in settings.
