An outdoor wireless base station having a housing and a circuit pack extending upwards in the housing with electronic components extending into a forward air flow passage. The forward air flow passage is interconnected for air circulation with a rearward air flow passage and a heat conductive rear wall of the housing partly defines the rearward flow passage. Air in the forward air flow passage flows upwards and into the rearward air flow passage for heat removal through the rear wall. The cooling air flows downwards in the rearward air flow passage to return to the bottom of the forward air flow passage.

Wireless base station-having cooling passages

An outdoor wireless base station with a circuit pack within a housing. A printed circuit board of the pack has opposite edges formed with spaced projections and the housing has spaced guide elements to receive the projections for mounting purposes. To mount the circuit pack, the circuit board is moved to pass the projections laterally between the guide elements to enable the projections to become aligned with and then to move along the guide elements.
