Abstract:
An enclosure device of a wireless communication apparatus, which has a tubular structure with increased heat dissipation not unknown heretofore. A section of the enclosure device has a polygonal or circular shape, such as a substantially cylindrical structure, and the enclosure, which has a plurality of radiation fins arranged on an outer surface of the enclosure in a vertical direction, is formed integrally with the radiation fins by using a compression method. Various communication devices of the wire communication apparatus are mounted on the interior of the enclosure. The structure is preferably formed by the radiation fins and exhibits an increased radiation effect than that of a structure where radiation fins are arranged side by side on a flat plane.
Abstract:
The present invention discloses a base station, the size of which is reduced and which is to be adopted in a mobile communication system. The disclosed small base station includes: a polyhedral housing; an antenna unit disposed on the widest surface of the outer surface of the housing; a first board arranged on any outer surface of the housing; and two or more boards which are arranged in an upright state with the first board and which are arranged to face three or more outer side surfaces of the housing, respectively.
Abstract:
Various embodiments of the present invention comprise: an antenna module; and at least one RRH which is arranged to face the outer surface of the antenna module, is coupled by being directly connected to the antenna module and arranged along the longitudinal direction of the antenna module, wherein a plurality of cooling air gaps are provided between the outer surface of the antenna module and the RRH.
Abstract:
A small-sized base station employed in a mobile communication system is disclosed. To this end, the small-sized base station in a mobile communication system, according to one embodiment of the present invention, is a base station device in a mobile communication system comprising: a case which has the shape of a polyhedron and is hollow inside; a housing accommodated inside the case and having the same polyhedron shape as the case; and at least one board which is positioned between the case and the housing.
Abstract:
The present invention is an apparatus for dissipating heat through a heat sink, the apparatus comprising: a heat transfer member having one end with a contact surface contacting a heating element arranged on a substrate and the other end with a contact surface contacting the heat sink, the heat transfer member transferring the heat generated from the heating element to the heat sink; an elastic member for providing elastic force for pushing the heat transfer member toward the heating element; a guide member arranged in the heat sink to form a contact surface contacting the heat transfer member, the guide member mechanically guiding the heat transfer member such that the heat transfer member may slide and move toward the heating element; and a spacing member inserted between the substrate and the heat sink so as to maintain a preset spacing when the substrate and the heat sink are fixed and attached with each other.
Abstract:
The invention relates to a base station antenna, comprising: two or more reflector plates, each provided with a radiating element; a ray dome defining an inner cavity therein and housing the reflector plates; a first and second cap coupled so as to cover each of openings defined in upper and lower portions of the ray dome; a reflector plate connecting member connected to each reflector plate and to the first and second caps, for enabling the rotation of the reflector plates; a reflector plate rotating driver including an actuator for providing rotational force, and a power-transmitting mechanism for transmitting the rotational force provided by the actuator to the reflector plates and controlling the rotational angles of the reflector pates, and the other is coupled to the first cap; a reflector plate fixing of the reflector plates; and a reflector plate controller providing, to the reflector plate rotating driver and the reflector plate fixing unit, control signals for controlling the rotation and stoppage of the reflector plates.
Abstract:
A multi-band antenna apparatus according to one of various embodiments of the present invention may comprise: an antenna housing in which an antenna module having two or more frequency bands is mounted; a plurality of repeaters detachably coupled to the antenna housing according to slide movement thereof; connector parts which protrude from the antenna housing and are connected to the plurality of repeaters, respectively; and a bracket which fixes the antenna housing to an outer wall and couples the plurality of repeaters to the antenna housing in an individually detachable manner.
