Street lighting pole base

A street lighting pole base, comprising:

• at least one upright outer wall defining an enclosed space of the street lighting pole base;
• a divider dividing the enclosed space into at least two bays arranged side by side, the at least two bays including a first bay and a second bay;
• an individual air inlet for the first bay provided at the bottom of the divider;
• first mounting means for mounting a first heat dissipating device used for wireless telecommunication in a first position in the first bay;
• second mounting means for mounting a second heat dissipating device used for wireless telecommunication in a second position in the first bay, which second position is vertically higher than the first position;
• and
• a sub-divider arranged in the first bay and adapted to split an airflow from the individual air inlet for the first bay into a first sub-airflow into a first sub-bay and intended to mainly cool the first heat dissipating device used for wireless telecommunication when mounted in the first position in the first sub-bay but substantially not the second heat dissipating device used for wireless telecommunication when mounted in the second position and a second sub-airflow into a second sub-bay and intended to mainly cool the second heat dissipating device used for wireless telecommunication when mounted in the second position in the second sub-bay but substantially not the first heat dissipating device used for wireless telecommunication when mounted in the first position.
