      本丸はUHF帯。T-mobileは600MHz帯で「独自5G」のサービスを開始した。ITUの標準化を待たなくても、テレビ局さえ協力すれば周波数はあけられる。 http://news.livedoor.com/article/detail/14901921/ …https://twitter.com/euroseller/status/1114527769424089089 …

      そしてHuaweiが先行しているのは5GHz以下なので，本格的に5Gが普及するころにHuaweiが先端を行っているかどうかは現時点では全く不明。 https://twitter.com/ikedanob/status/1114524966496526336 …

      今「5G携帯」といっているのは、4Gと5Gの半導体を入れて、5Gの基地局のある所（ごくせまいエリア）だけ5Gを使っているので、切り替えに失敗すると切れる。そんな携帯をあわてて買う必要はない。

      総務省はITUが標準化しないと動かないが、アメリカはITUなんか無視して5Gサービスを始めている。EUでも標準化が始まった。日本は技術的にはいちばん進んでいるのに、最後尾になりそうだ。

      同じ話を繰り返すのも面倒なので、2017年の規制改革推進会議の議事録。総務省も事実関係は認めた。 https://www8.cao.go.jp/kisei-kaikaku/suishin/meeting/wg/toushi/20171024/gijiroku1024.pdf …
