QRmap: executable QR codes for Navigation in Industrial Environments and Beyond
Stefano Scanzio, Paolo Campagnale, Pietro Chiavassa +1
QR codes are nowadays customarily used for embedding static data such as web hyperlinks or plain text. The sQRy technology (executable QR codes) permits to embed executable program…
Performance Evaluation of Parallel Wi-Fi Redundancy with Deferral Techniques
Gianluca Cena, Pietro Chiavassa, Stefano Scanzio
Wireless communication is increasingly used in industrial environments, since it supports mobility of interconnected devices. Among the transmission technologies operating in unlic…
Wi-Fi Rate Adaptation for Moving Equipment in Industrial Environments
Pietro Chiavassa, Stefano Scanzio, Gianluca Cena
Wi-Fi is currently considered one of the most promising solutions for interconnecting mobile equipment (e.g., autonomous mobile robots and active exoskeletons) in industrial enviro…
Widening the Coverage of Reference Broadcast Infrastructure Synchronization in Wi-Fi Networks
Gianluca Cena, Pietro Chiavassa, Gabriele Formis +1
Precise clock synchronization protocols are increasingly used to ensure that all the nodes in a network share the very same time base. They enable several mechanisms aimed at impro…
Analysis of the operation of a TSN switch and other devices using executable QR codes
Stefano Scanzio, Pietro Chiavassa, Gianluca Cena
Executable QR codes, also known as sQRy, are a technology aimed at inserting executable programs in a QR code. Through a concrete example, in this paper, we demonstrate their usage…
Compression of executable QR codes or sQRy for Industry: an example for Wi-Fi access points
Stefano Scanzio, Gabriele Formis, Pietro Chiavassa +2
Executable QR codes, or sQRy, is a technology dated 2022 that permits to include a runnable program inside a QR code, enabling interaction with the user even in the absence of an I…
