• BTS configuration
• ambient temperature
• direction of the temperature change
The power consumption is higher when the ambient temperature is decreasing
and the heating power of the BTS is increasing. When the ambient temperature
rises, the heating power reduces. Consequently, the power consumption of the
Nokia MetroSite EDGE Base Station at a given temperature varies according to
the direction of temperature change. Figure 4 presents the power consumption
values at different ambient temperatures for three BTS configurations.
