5G in Modo Semplice e Approfondito

by Ajit Singh

La quinta generazione di tecnologie di accesso wireless (5G) si trova di fronte all'arduo compito di soddisfare le costanti richieste di velocità di trasmissione dati e capacità di sistema più elevate, nonché di un'ampia gamma di applicazioni e di requisiti di qualità dell'esperienza (QoE) degli utenti. Sebbene non sia ancora standardizzata, la tecnologia 5G dovrebbe offrire un throughput significativamente più elevato rispetto all'evoluzione a lungo termine (LTE), avere una latenza nell'ordine dei millisecondi ed essere in grado di accogliere e supportare la prevista esplosione dei dispositivi dell'Internet delle cose (IoT). Nuovi tipi di dispositivi (ad esempio sonde, contatori, sensori, attuatori) contribuiranno in modo significativo all'aumento del traffico e nuovi settori di mercato porteranno nuove priorità (ad esempio le infrastrutture critiche). Questo libro è una panoramica completa dello stato attuale del 5G. Spiega tutto, dai casi d'uso più probabili, agli aspetti dello spettro, da un'ampia gamma di opzioni tecnologiche alle potenziali architetture di sistema 5G, ed è un riferimento indispensabile per accademici e professionisti coinvolti nelle comunicazioni wireless e mobili. Vengono riassunti gli sforzi di ricerca a livello mondiale e vengono descritte e spiegate le tecnologie dei componenti chiave, tra cui D2D, comunicazioni a onde millimetriche, massive MIMO, coordinated multi-point, codifica delle reti wireless, gestione delle interferenze e problemi di spettro. Viene affrontata l'importanza del 5G per i settori automobilistico, manifatturiero, energetico, della vendita al dettaglio e dell'assistenza sanitaria, nonché la relazione tra IoT, comunicazioni di tipo macchina e sistemi cyber-fisici. Questo libro fornisce una solida visione dell'evoluzione, dell'architettura, del protocollo dello stack di rete, delle applicazioni e, naturalmente, delle sfide e delle prospettive future del 5G.

60-GHz CMOS Phase-Locked Loops

by Reza Mahmoudi Arthur H.M. Roermund Hammad M. Cheema

The promising high data rate wireless applications at millimeter wave frequencies in general and 60 GHz in particular have gained much attention in recent years. However, challenges related to circuit, layout and measurements during mm-wave CMOS IC design have to be overcome before they can become viable for mass market. 60-GHz CMOS Phase-Locked Loops focusing on phase-locked loops for 60 GHz wireless transceivers elaborates these challenges and proposes solutions for them. The system level design to circuit level implementation of the complete PLL, along with separate implementations of individual components such as voltage controlled oscillators, injection locked frequency dividers and their combinations, are included. Furthermore, to satisfy a number of transceiver topologies simultaneously, flexibility is introduced in the PLL architecture by using new dual-mode ILFDs and switchable VCOs, while reusing the low frequency components at the same time.
