National Cold Vault Deploys Cellular Monitoring to Prevent Drug Spoilage
When facility power grids collapse during extreme weather, standard Wi-Fi-dependent refrigeration loggers go dark, leaving high-value biologics and vaccines at risk of silent destruction. Carrollton-based National Cold Vault is now countering this vulnerability by deploying an autonomous, grid-independent 4G LTE-M telemetry system designed to bypass local IT firewalls entirely.
