サマリー

5Gがやっと標準化された。しかしすでに、すべてのスペクトル帯域において非常に高いデータレートをどこでも提供することのできる新しい周波数帯を模索し始める5Gネットワークもある。2015年の世界無線通信会議(WRC-15)において、IMT(第4世代移動通信システム等)利用のための周波数帯が割り当てられた。欧州での最初のバンドは700メガヘルツと3.4-3.8ギガヘルツとなるだろう。ミリ波周波数は、現在は学術や工業レベルの互換性研究目的とされている。バンド選択の地域間の競争が過熱している。世界中で5Gは、より広い周波数帯の1ギガヘルツ以下、6ギガヘルツ以下、6ギガヘルツ以上の3つのバンドタイプに集約していくだろう。そのため、ほとんどは技術的な実現性と伝搬特性に基づいた消費者や利用事例のニーズとで折り合っていくだろう。

フランスの調査会社イダテ社(IDATE)の調査レポート「5Gスペクトラム:いつどのバンドが?」は、5Gスペクトラムに関する法規制の現状と5G利用の今後のバンドについて記載している。6ギガヘルツ以下の5Gネットワークやミリ波バンドに使用されるバンドについても記載している。

Summary

5G has yet to be standardised. However, some 5G networks are already seeking new frequencies to provide very high data rates everywhere, in all spectrum ranges.

A set of frequencies were allocated to IMT use at WRC-15. The first bands in Europe will be the 700 MHz band and the 3.4-3.8 GHz bands. Millimetre frequencies are currently the object of compatibility studies at academic and industrial levels.

Competition is heating up between regions on which bands to select. Globally, 5G will aggregate more spectrum in the three types of bands i.e. sub-1 GHz, sub-6 GHz and above 6 GHz.

It will mostly result in a trade-off between technical feasibility and consumer/use case needs based on propagation characteristics.

This report presents the regulatory status associated to 5G spectrum and presents the future bands for 5G use. It also analyses the bands likely to be used by 5G networks below 6 GHz and in millimetre bands.
