Il nuovo standard di comunicazione wireless 6G dovrà affrontare sfide significative per migliorare le prestazioni di comunicazione e raggiungere nuovi obiettivi. Questi obiettivi includono sia la densificazione della rete e una solida connettività a banda larga nelle aree urbane, che l'espansione della rete per raggiungere e connettere dispositivi attualmente esclusi a causa della posizione geografica, dei limiti di consumo energetico, o altri ostacoli. In linea con le ultime tendenze della ricerca LoRa, il nostro studio si concentra sullo sviluppo di uno scenario di rete non terrestre (NTN) basato su satelliti LEO e architettura LPWAN. LoRaWAN è una rete ampiamente diffusa per dispositivi IoT, opera attraverso la cooperazione device-gateway-server. Questa ricerca inizia studiando dal livello fisico al link-layer di LoRa per la comunicazione dispositivo-gateway per poi concentrarsi sull'identificazione e l'implementazione delle modifiche necessarie per adattare l'architettura di rete ed il server LoRaWAN a uno scenario NTN, in cui i satelliti LEO vengono utilizzati come gateway per raccogliere dati da sensori LoRa. Attraverso i nostri test e simulazioni, dimostriamo l'applicabilità dello scenario NTN proposto sull'architettura Lora e sui satelliti LEO.

Abstract
The upcoming sixth-generation wireless communication standard, will face significant challenges in improving communication performance and achieving new objectives. These objectives include network densification and robust broadband connectivity in urban areas, as well as the expansion of networks to reach and connect devices that are currently excluded due to geographical location, power consumption constraints, or any kind of obstacle. In line with the latest LoRa research trends, our study focuses on developing a Non-Terrestrial Network (NTN) scenario on LEO satellites and LPWAN architecture. LoRaWAN is a widely spread network for IoT devices, it operates through device-gateway-server cooperation. This research starts by studying the physical and link layers of LoRa on device-gateway communication to then focus on identifying and implementing the modifications required to adapt the LoRaWAN network architecture and server to a NTN scenario, where a LEO satellites are used as Gateways to collect data from the LoRa sensors. Through our tests and simulations, we demonstrate the applicability of the proposed NTN scenario on Lora architecture and LEO satellites.File | Dimensione | Formato | |
