Summary

米国調査会社ABIリサーチの調査レポート「【分析レポート：アプリケーション】5Gミリ波の採用」は、最新のミリ波の進化について明示し、動画監視、ベニュー、製造業、専用屋内ネットワークなどの主要な利用ケースについて記載している。固定無線接続（FWA）の3つのタイプ（家庭への無線、ビルとWi-Fi AC、スモールセルのバックホール）と今後について広範に査定している。23か国の高周波数帯の割当とEバンドの長期的な可能性についても記載している。広帯域周波数帯がもはやP2Pバックホールによって奪われないこと、ミリ波がセルラー接続の一部となること、長期的にはさらに高い帯域を征服することなどについても記載している。

The demand for connectivity in the 5G era is more fragmented than ever before, and the currently used spectrum is simply not enough to satisfy the huge variety of connectivity needs. The experienced bandwidth shortage has motivated the wireless ecosystem to start using the relatively under-utilized spectrum over 24 GHz, which are referred to as millimeter waves (mmWaves). This set of higher spectrum bands promises to unleash a large bandwidth opportunity for cellular mobile communications. The report examines why the use of these high-band frequencies not only open doors to a vast amount of network capacity, but how its lower cost-per-bit attribution and fiber-like speed will also bring enhanced mobile experiences to a huge variety of different end users. In the first phrase, mainly with Fixed Wireless Access (FWA) and Point-to-Point connectivity, and later on Point-to-Multipoint connectivity to stadiums, concert halls, airports, venues, train stations, and dense urban areas are expected to be the first locations to use mmWave technology.

This report explores the upcoming mmWave related developments and presents leading use cases such as video surveillance, venues, manufacturing, and private indoor networks. The report also extensively examines FWA, its three main types (Wireless to the Home, Wireless to the Building and Wi-Fi AC and Small cell backhauling) and future prospects. The report also presents the expected high-band spectrum allocation for 23 countries and the long-term potential of the E Band. Overall, this report helps to understand why high-band spectrum is no longer usurped by P2P backhaul and how mmWaves will become part of cellular connectivity, and in the long term will conquer even higher bands.
