How does Radio Over IP Technology Maintain Communication During a Major Cellular Network Blackout?

When a major cellular network blackout strikes, modern reliance on data-driven mobile devices often collapses instantly. Connectivity that professionals depend on for coordination vanishes, leaving important operations in the dark. Radio over IP (RoIP) bypasses these fragile public infrastructures by digitizing voice signals and transmitting them across private, hardened networks.

How network change management could've prevented a costly switch misconfiguration

Unplanned outages often trace back to a simple but overlooked cause: an untracked configuration change. In many organizations, network device configurations are updated manually without approvals, documentation, or rollback plans. This lack of structure can lead to performance issues, downtime, and compliance risks. In this blog, we'll see how a core switch misconfiguration exposed the risks of unmanaged changes.
