Question: In Telecommunication Performance Management, what is the unit of measurement for the 'Energy' performance measurement, as defined for BTS (Base Transceiver Station) Measurement Functions?
Option 1: Degree Celsius (C°)
Option 2: Watt (W)
Option 3: kilo Watt hour (kWh)
Option 4: Joule (J)
Explanation: The correct unit for measuring energy consumption in the context of telecommunication performance management, specifically for BTS Measurement Functions, is kilo Watt hour (kWh). This unit accurately reflects the energy consumed over a period, which is crucial for assessing and optimizing the power efficiency of telecom infrastructure. In contrast, Degree Celsius (C°) measures temperature, Watt (W) measures power at a single point in time, and Joule (J) measures energy but is not the specified unit for this particular measurement.
