What is a telemetry performance metric?

• A. Network topology diagrams
• B. Data rate, latency, jitter, packet loss, BER, availability, reliability, and power consumption
• C. Only data rate
• D. User satisfaction scores

Answer: (C)

Telemetry performance is captured by a set of metrics that describe how well the data gets from remote sensors to the receiver in a timely, reliable way. Data rate alone doesn't tell whether the data arrives on time or intact; you also need latency, jitter, packet loss, BER, availability, reliability, and even power consumption to fully evaluate how the telemetry link behaves under real conditions. These metrics together reflect throughput, timing, data integrity, uptime, and energy efficiency, which are all crucial for making timely decisions in telemetry systems. Other options miss important aspects: diagrams describe structure, not performance; user satisfaction is about perception, not transport quality.
