みなさま、お元気でお過ごしでしょうか?

今回は5Gについての記事を一部選抜し解説を行いたいと思います。

“5G” is the next generation – the fifth generation – of wireless networks. 5G is a technology you’ll probably want, or eventually have to adopt, depending on your appetite for innovation versus wireless bugs and growing pains. 5G networks will bring us much more than a simple bandwidth or “speed” improvement on phones: Critical improvements like low latency, intelligent power consumption, high device density and network slicing make it a breakthrough — and a technical, confusing bore for many consumers who just want to know what it will do for them.

(1) In a nutshell, 5G will dramatically improve the responsiveness of all the current technologies on your phone, as well as make it possible for your home internet to come over the air rather than a telephone wire, cable or satellite dish. Later it will make possible new experiences that are still fringe, like augmented reality that works well anywhere, smart cities that are safer, cleaner and more efficient, and a truly connected car.

5G does emit “microwave” radiation, but so does anything using 4G, Wi-Fi and Bluetooth. The point of contention is whether 5G’s number of antennas, proximity of antennas and the power levels coming from them make it hazardous. Conventional scientific wisdom has long held that radio waves don’t become dangerous to our bodies’ cells, or “ionizing,” until they reach frequencies found in X-rays, gamma rays and light from the sun. Even the highest 5G frequencies sit far below those types of radiation and are, therefore, considered safe or “nonionizing.”

(2) The bottom line on 5G safety is that the safety of cellular networks in general has been in dispute since at least the early ’90s, as well as that of radiation from power lines, which are of extremely low frequency. Anything with the word “radiation” attached to it is going to come in for fearsome speculation.

(1) In a nutshell, 5G will dramatically improve the responsiveness of all the current technologies on your phone, as well as make it possible for your home internet to come over the air rather than a telephone wire, cable or satellite dish.

簡潔に言うと、5Gはスマホなどの端末がもっと早く反応する様になり、自宅でインターネットに接続するときに従来のケーブルなどに頼らず接続出来るようになります。

話を簡単にまとめたい時、英語では「In a nutshell」という表現を使います。

NutshellはNut=木の実、Shell=殻

In a nutshell の語源は「話を木の実の殻に詰める」から来ています。

 

(2) The bottom line on 5G safety is that the safety of cellular networks in general has been in dispute since at least the early ’90s, as well as that of radiation from power lines, which are of extremely low frequency.

結論から言うと5Gの安全性は90年代初期から論争されていました。送電線の放射線量も低いにも関わらず、安全性を心配する人たちがいました。

Bottom line はネイティブがよく使うフレーズのひとつで、「要するに」と言う意味合いを持ちます。

例)What is the bottom line?

要するに何が言いたいの?

 

いかがでしたか?今回は話をまとめたい時に使うフレーズを紹介しました。

Gでどんな世の中になるか楽しみですね!
