backbone of edge connectivityThey serve as the , forming the critical bridge between field devices, cloud systems, and central control platforms.

Understanding Edge Connectivity and Its Importance

Edge connectivityedge computing refers to the ability of edge devices — such as sensors, controllers, and gateways — to exchange data efficiently with other devices or the cloud. Instead of sending all data to centralized data centers, processes information locally to reduce latency and bandwidth usage.

For edge systems to function effectively, connectivity must be:

Reliable: No data loss during transmission
Low-latency: Real-time decision-making at the edge
Secure: Protected from cyber vulnerabilities
Redundant: Capable of switching networks if one fails

Without such robust connectivity, edge networks risk delays, communication breakdowns, and inaccurate analytics — all of which can affect production efficiency, safety, and business continuity.
