What is the primary function of the local gateway/edge device in telemetry data flow?

• A. Renders dashboards at the edge for clinicians.
• B. Performs bulk data analytics at the edge.
• C. Transfers data only when network is available.
• D. Timestamps and buffers data before transmission to central server

Answer: (B)

The key idea is that the edge gateway brings processing closer to the data source, so raw telemetry can be analyzed locally rather than sent in full to a central server. By performing analytics at the edge, the gateway can extract meaningful insights, run anomaly detection, summarize data, and determine which results or alerts are important enough to forward. This reduces bandwidth needs and enables faster response, especially when network connectivity is limited or intermittent.

Visual dashboards for clinicians are typically generated from processed data or centralized systems, not solely the gateway’s job. Transferring data only when the network is available and simply timestamping or buffering before sending are important supporting functions, but the primary role of the edge device is the analytics it performs locally to produce actionable information.
