5Gには、Low Band(600MHz~850MHz)、Mid Band(1GHz-6GHz)、High band(24GHz-40GHz)の3つの周波数帯があります。

米国では、High BandのmmWave戦略を取っていたので、Mid bandは、長らく国が占有していたため、民間への開放(オークション)が遅くなったという経緯があります(その影響により、中国企業に技術開発を先行されてしまい、企業の締め出し政策となります)。

そして、2021年2月(図①)と2022年2月(図②)のオークションにより、Mid Bandの一部分が民間に開放されました。すでに①に関しては、現在利用できるブロックが制限されていますが、VerizonとAT&Tがサービスを開始しており、順次広がっている状態です。2023年末にブロック制限が解除されるため、2024年から本格的な5G利用となるというのが大方の予想です。

As organizations accelerate digitally, their attack surface expands and network complexity rises. Simultaneously, cyber threats are becoming more automated and innovative. To deliver the expected secure, high-performance user-to-application connection, today’s organizations require a new approach.

According to Gartner, cybersecurity mesh architecture (CSMA) is one of the top strategic technology trends for 2022. It claims that incorporating cybersecurity mesh into collaborative ecosystems will reduce financial losses from cybersecurity attacks by 90%.
