The NSDN W59 is a widely deployed industrial wireless gateway. This paper presents the design, implementation, and validation of a secure over-the-air (OTA) software download system for the W59, addressing firmware integrity, version rollback prevention, and bandwidth efficiency. Experimental results show a 99.97% success rate over cellular networks and a 45% reduction in download time compared to the legacy FTP-based method. Nsdn W59 Software Download
The proposed software download mechanism significantly improves reliability and security for NSDN W59. Future work includes multicast updates for large fleets. It looks like you're asking me to generate
