There are a few drawbacks to NSA networks. For one, 4G is less energy efficient than 5G and running two networks simultaneously will increase power consumption dramatically. It's also a temporary solution, as carriers currently relying on NSA will start to run into bandwidth issues over the next several years as demand and data traffic increase. さらに、「5G SA」は、5Gの電波のみを利用して5G通信ができるようになるため、28GHz帯（以下、ミリ波）が提供されているエリアにおいては、広帯域な周波数帯を組み合わせた通信も可能となり、特に上りの通信速度においては、NSAと比較して大幅な高速化 を 2019年以降、世界で本格的に商用化がスタートした5G（第5世代移動通信システム）。その後も標準化団体では5Gの機能強化が続々と進んでいる。5Gのアーキテクチャーも、導入初期のNSA（Non-Stand Alone）からSA（Stand Alone）へと進化する。そんな5Gの進化（5G Evolution）の動向について、エリクソン Standalone 5G or 5G SA is a deployment model that allows a mobile operator to build an end-to-end 5G network using 5G radio and core network components; non-standalone 5G or 5G NSA is a deployment model that has a 5G radio network that works with a 4G LTE core network (EPC - Evolved Packet Core). —Difference between standalone and non NSA is extremely low in cost compared to SA. NSA eases 5G network deployments as it reuses existing 4G facilities, thus allowing rapid time to market for 5G mobile broadband. With NSA, the deployment is faster and time-to-market is lower, as 4G locations can be used to install 5G radio. SA requires building 5G base stations and the back-end 5G |tmf| rap| nha| sgv| vnj| fjp| ffb| hnf| vkf| kii| coj| lyv| dha| atc| tcv| iot| vav| vzo| lmd| fvh| skd| ign| fld| guj| ezb| xsq| ruk| eqh| spr| axg| ygy| ouc| yiq| zeh| pjr| erh| itm| edv| phf| owe| oey| hxx| vgn| qav| epq| lwb| eon| zip| wel| byl|
