For example, two ventilation openings 211 may be disposed on the side walls of the cabinet body 210, specifically, two ventilation openings 211 may be disposed on two opposite side walls, or two ventilation openings 211 may also be disposed on two adjacent side walls, but a certain distance should be provided between the two ventilation openings 211, so as to ensure the ventilation and heat dissipation effects.

To further enhance the ventilation and heat dissipation effects, at least one fan 510 may be disposed inside the cabinet 210, and the fan 510 is disposed near the ventilation opening 211 to enhance the air circulation inside the cabinet 210. When two ventilation openings 211 are formed in the cabinet 210, two fans 510 may be disposed in the cabinet 210, wherein one fan 510 may be an exhaust fan 510, and the other fan 510 may be an exhaust fan 510.

Specifically, as shown in fig. 1, the vent 211 for air outlet may be disposed above the vent 211 for air inlet, and since the hot air is lighter in weight and is collected above the cabinet body 200, the vent 211 for air outlet may be disposed above the vent 211 for air inlet to discharge more hot air out of the cabinet body 210, so as to enhance the heat dissipation effect.

It should be understood that the ventilation openings 211 may be disposed on the left, right, and bottom sides of the cabinet body 210 as shown in fig. 1, but should not be disposed on the side wall of the top side of the cabinet body 210, so as to prevent rainwater from flowing into the cabinet body 200, causing a safety hazard and causing damage to the components such as the base band unit 300 in the cabinet body 200.

In addition, a photosensitive device 520 may be further disposed in the cabinet 210, and the photosensitive device 520 is electrically connected to the fan 510. When the cabinet door 220 is opened, ventilation does not need to be enhanced at the moment, the photosensitive device 520 senses light and controls the fan 510 to stop running so as to save electricity; when the cabinet door 220 is closed, the light sensing device 520 does not sense light, and the fan 510 is controlled to be started to achieve the effects of ventilation and heat dissipation.

To avoid the sensing error of the photosensitive device 520, a baffle 2111 may be disposed at the vent 211 to prevent the too strong light from entering the cabinet body 200 through the vent 211. Besides blocking light, the baffle 2111 also has a function of rain shielding, so that rainwater can be further prevented from flowing into the cabinet body 200, and potential safety hazards are avoided.

In other embodiments of the present application, the baseband unit cabinet may include more or fewer components than shown, or combine certain components, or split certain components, or a different arrangement of components. For example, the area of the side wall located at the top side of the base band unit cabinet may extend beyond the side walls and/or the cabinet door 220 at the left and right sides to block rain.
