Technical Field
The present disclosure relates to the field of base station antennas, and more particularly, to a mounting apparatus for mounting a remote radio unit to a base station antenna, and a base station antenna system.
Background
In a wireless communication network, a base station antenna may be provided with a Radio Remote Unit (RRU), and the two may be electrically connected to each other through a jumper. Typically, the base station antenna and the remote radio unit may be separately mounted on different poles, and thus, separate mounting spaces are required for not only the base station antenna but also the remote radio unit. The relative positions of the base station antenna and the remote radio unit can only be determined at the installation site, and therefore, the length of a jumper wire for electrically connecting the base station antenna and the remote radio unit to each other cannot be determined in advance.
For some base station antennas, they may be first mounted to a pole and then a remote radio unit, which is mated to the base station antenna, may be attached to the base station antenna, where the remote radio unit is suspended and transported to a predetermined mounting location during installation. However, the orientation of the bulky remote radio unit under gravity when suspended may be different from the orientation required for installation, and the tether used to suspend the remote radio unit may interfere with surrounding structures during installation, both of which may make installation of the remote radio unit difficult.

Detailed Description
A base station antenna system and a mounting device 3 for mounting a remote radio unit 2 to a base station antenna 1 according to an embodiment of the present invention are described below with reference to fig. 1 to 5.
Fig. 1 is a perspective view of a base station antenna system according to an embodiment of the present invention, and fig. 2 is an exploded view of the base station antenna system of fig. 1. As shown in fig. 1 and 2, the base station antenna system includes a base station antenna 1 and a remote radio unit 2, wherein the remote radio unit 2 is mounted to the base station antenna 1 by means of a mounting device 3. The base station antenna 1 and the remote radio unit 2 can be preassembled by means of the mounting device 3 and then mounted on a mast, likewise not shown, by means of the connecting element 7 and a clamping device, not shown, connected to the connecting element 7. It is also possible that the base station antenna 1 is first mounted to the mast and then the remote radio unit 2 is mounted to the base station antenna 1 by means of the mounting device 3. For this purpose, first of all, the individual guide rails 4 can be mounted to the base station antenna 1 and the guide elements 8 can be mounted to the remote radio unit 2, then the remote radio unit 2 can be pushed into the guide rails 4 by means of the guide elements 8 from the side until a predetermined mounting position relative to the base station antenna 1 is reached, and finally the remote radio unit 2 is fixed to the base station antenna 1 by means of the fixing device. In the mounted state of the guide 4 on the base station antenna 1, the guide 4 extends laterally. The guide element 8 is movable along said guide rail 4. When maintenance of the base station antenna system is required, the remote radio unit 2 can also be detached from the base station antenna 1, wherein the fastening device can first be released and the remote radio unit 2 can then be removed from the guide rail 4 by means of the guide element 8.
The mounting device 3 may comprise a mounting frame 5, which mounting frame 5 is configured for mounting to the base station antenna 1, for example may be fixed on an antenna cover of the base station antenna 1 by means of a bolt connection device. The mounting frame 5 can comprise two longitudinal beams 6 which are parallel to one another and two connecting elements 7 which connect the two longitudinal beams to one another at the respective ends of the two longitudinal beams, the two connecting elements 7 can each be connected to a clamping device, not shown, which can be fastened to a holding pole, also not shown.
The mounting means 3 may comprise an adapter plate 9, the adapter plate 9 being configured for mounting to the RRU 2, and the guiding element 8 may be an integral part of the adapter plate 9. It is also contemplated that the guide element 8 and the adaptor plate 9 may be separate components and separately mounted to the remote radio unit 2.
Fig. 3 is a perspective view of the guide rail 4 of the mounting device 3 of the base station antenna system of fig. 1. The guide rail 4 can have side walls 11 lying opposite one another, which side walls 11 extend transversely in the mounted state of the guide rail 4 on the base station antenna 1 and are designed to receive and guide the guide element 8 between the side walls 11. The side walls 11 can be flared in order to make it easier to place the guide element 8 into the guide rail 4. The guide rail 4 may have a row of pulleys 12 defining a guide path for the guide element 8. Only one of the pulleys is provided with reference numeral 12 in fig. 3. The guide rail 4 can be fixed directly to the antenna housing of the base station antenna 1. However, in the embodiment shown in fig. 3, the guide rail 4 can also be fixed to the two longitudinal beams 6 of the mounting frame 5 by means of bolts 13 and thus indirectly to the base station antenna 1. In the state of mounting the remote radio unit 2 on the base station antenna 1, the guide rail 4 may be located below the remote radio unit 2. The guide element 8 may have a recess which, in the predetermined mounting position of the radio-frequency unit 2, may be above one of the pulleys, so that the guide element 8 may be lowered slightly, which pulley is partially received in the recess. The predetermined installation position of the remote radio unit 2 can be clearly sensed.
When the remote radio unit 2 is in a predetermined mounting position relative to the base station antenna 1, the remote radio unit 2 can be fixed to the base station antenna 1 by means of a fixing device. Fig. 4 is a top view of a portion of the base station antenna system of fig. 1, and fig. 5 is a cross-sectional view along section line a-a of fig. 4. One embodiment of the securing device is shown in fig. 4 and 5. The fastening device comprises four snap lock means 10, which snap lock means 10 are configured for locking the adapter plate 9 on the longitudinal beams 6, wherein each longitudinal beam 6 is associated with two snap lock means 10 spaced apart from each other. For example, the longitudinal beam 6 and the adapter plate 9 can have non-circular mounting holes, the quick-lock device 10 can be inserted into and pulled out of the mounting holes in a first orientation relative to the mounting holes, the quick-lock device 10 can be held in the mounting holes in a second orientation relative to the mounting holes, which is different from the first orientation (for example, rotated by 90 ° relative to the first orientation), and the locking of the quick-lock device 10 can be achieved by pressing down on a handle of the quick-lock device 10. It is also possible to fasten the adapter plate 9 to the longitudinal beam 6 and thus to fasten the remote radio unit 2 indirectly to the base station antenna 1 by means of screw connections.
Fig. 6A to 6C are schematic diagrams describing an installation process of the remote radio unit 2, in which the base station antenna 1 has been installed to a boom, not shown, and the remote radio unit 2 is to be installed to the base station antenna 1. As shown in fig. 6A, the remote radio unit 2 may be lifted to the side of the predetermined installation position. The guide element 8 may then be placed into the rail 4 and the radio-frequency unit 2 may be pushed along the rail 4 until the predetermined mounting position is reached. Fig. 6B shows the remote radio unit 2 moved along the guide rail 4 in the lateral direction to approach the predetermined mounting position, and fig. 6C shows the remote radio unit 2 moved along the guide rail 4 in the lateral direction to the predetermined mounting position. The radio remote unit 2 can then be rotated towards the base station antenna 1 so that the adapter plate 9 rests on the two longitudinal beams 6 of the mounting frame 5. Finally, the adapter plate 9 can be locked to the longitudinal beam by means of the quick-locking device 10 and thus the radio remote unit 2 can be fixed to the base station antenna 1 in the predetermined installation position.
