A thermal management system and process for use in a wireless access point antenna housing. The access point typically includes two or more stacked antenna housings or bays. Each bay includes an upper end, a lower end spaced from the upper end, and at least one sidewall surface extending between the upper end the lower end to define an enclosed interior area of the bay. Each bay typically includes a plurality of antennas. In an arrangement, the upper end, lower end and a one or more partitions between the upper and lower ends in conjunction with one or more sidewall surfaces form the antenna bays. In an arrangement, divider panels form the partitions and/or the upper and lower ends. Each partition panel includes one or more airflow channels that provide an air inlet and/or outlet for at least one adjacent antenna bay.

The invention relates to a light element of a vehicle with at least one light source configured to emit light rays, a reflective layer. With a pattern made wholly or partly in the reflective layer. The light element further including an optical element configured to project the light rays from the at least one light source towards the reflective layer. With a dark layer extending along the optical element on the side opposite the reflective layer.

An antenna housing that is generally ovular such that a sidewall of the housing has two curved surfaces (e.g., rounded ends) on opposing ends of the housing. The ovular shape of the housing allows a center of curvature of each rounded end to be disposed within an interior of an antenna bay(s) within the housing. In such an arrangement, the placement of the centers of curvature within the antenna bays allows for pivotally mounting individual antennas at or near the center of curvature. This allows pivoting the antennas within the antenna bay while maintaining a normal vector (e.g., extending normal to an emitting surface of the antenna) nearly perpendicular with an inside surface of shroud surrounding the antenna housing thereby reducing RF reflection and/or scatter.

Access points can be mounted in a variety of locations or orientations and can support multiple communications protocols. In some embodiments, an access point includes a main housing and a front housing. The main and front housing are connected by a hinge. A Wi-Fi antenna is included in the front housing in some embodiments. The access point is configured for use in either an open or closed position. When mounted in a vertical position, the front housing can be lowered into a horizontal position, which facilitates a preferred orientation of an antenna with respect to the ground. A first set of cooling fins serves to maintain components of the access point offset from a wall to which the access point is mounted. This facilitates airflow. Additional fins act as a spacer between the main housing and the front housing when the access point is used in a closed position. This facilitates air flow around both sides of the main housing.
