reti wireless 5g 6g
I progressi delle reti wireless 5g e 6g guidano l'innovazione nella telefonia mobile comunicazione grazie al miglioramento della velocità dei dati, della latenza e della connettività.

Le reti wireless 5G e 6G rappresentano progressi rivoluzionari nella tecnologia delle comunicazioni mobili, incrementando velocità di trasmissione dati, latenza e densità di connettività. Il 5G ha introdotto innovazioni come il massive mimo, l'utilizzo dello spettro delle onde millimetriche e il network slicing per supportare diverse applicazioni, dalla banda larga mobile potenziata alla comunicazione a bassa latenza ultra-affidabile. Su queste basi, il 6G prevede comunicazioni terahertz e superfici riflettenti intelligenti per raggiungere una velocità di trasmissione e un'efficienza spettrale senza precedenti. L'integrazione di tecniche di edge computing e machine learning ottimizza dinamicamente le prestazioni di rete e l'allocazione delle risorse.
