Abstract

A mounting base ( 14 ) is fixed to an antenna ( 13 ) or an antenna bracket ( 15 ) for supporting the antenna ( 13 ). A baseband unit ( 11 ) and an RF unit ( 12 ) are fixed to the mounting base ( 14 ). The baseband unit ( 11 ) fixed to the mounting base ( 14 ) is disposed to face a back part ( 132 ) of the antenna ( 13 ) and to form a space between the back part ( 132 ) and the first enclosure ( 111 ). The RF unit ( 12 ) fixed to the mounting base ( 14 ) is disposed in the space formed between the back part ( 132 ) of the antenna ( 13 ) and the baseband unit ( 11 ) and is coupled to a waveguide flange ( 132 ) of the antenna ( 13 ). Thus, for example, in a configuration of a point-to-point wireless apparatus in which an RF unit and a baseband unit are separated, restrictions on installation space of the apparatus can be facilitated.

Claims (37)

1 . A wireless outdoor communication apparatus comprising:

a first device comprising a first enclosure;

a second device comprising a second enclosure separate from the first enclosure,

wherein the first enclosure is configured to accommodate a baseband circuit configured to perform digital baseband signal processing,

wherein the first device is protected according to a first degree of protection from water and dust ingress,

wherein the first enclosure includes a first surface that faces toward a back part of an antenna,

wherein the first surface includes a recessed region surrounded by a peripheral region provided with heat-dissipation fins,

wherein the first enclosure includes a first interface for communication with an external apparatus and a second interface for communication with the second device,

wherein the second enclosure is configured to accommodate an RF (Radio Frequency) circuit configured to perform RF signal processing,

wherein the second device is protected according to a second degree of protection from water and dust ingress; and

a mounting bracket configured to support the first device to be arranged adjacently to the second device with a space between the first enclosure and the second enclosure within the recessed region,

wherein the second device is supported by the mounting bracket within the recessed region so as to be disposed between the first enclosure and the back part of the antenna.

2 . The apparatus according to claim 1 , wherein the mounting bracket comprises a plate, a first stay member rising from one end of the plate, and a second stay member rising from another end of the plate.

3 . The apparatus according to claim 1 , wherein the first device and the second device each provides a degree of ingress protection of at least IP66 according to IEC 60529 defined by International Electro technical Commission (IEC).

4 . The apparatus according to claim 1 , wherein the mounting bracket is configured so that the second device is positioned between the first device and the mounting bracket.

5 . The apparatus according to claim 1 , wherein the mounting bracket is configured to support the first device in a manner such that the first device is arranged next to the second device.

6 . The apparatus according to claim 1 , wherein a communication cable is connected to the first interface.

7 . The apparatus according to claim 1 , wherein at least one of the first device and the second device is directly coupled to the mounting bracket.

8 . The apparatus according to claim 1 , wherein the first enclosure is configured to protect the first device according to the first degree of protection from water and dust ingress, and the second enclosure is configured to protect the second device according to the second degree of protection from water and dust ingress.

9 . An installation method of a wireless outdoor communication apparatus, the method comprising:

connecting a communication cable for communication with an external apparatus to a first interface of a first device; and

supporting, by a mounting bracket, the first device to be arranged adjacently to a second device,

wherein the first device comprises a first enclosure,

wherein the first enclosure is configured to accommodate a baseband circuit configured to perform digital baseband signal processing,

wherein the first device is configured to be protected according to a first degree of protection from water and dust ingress,

wherein the first enclosure includes a first surface that faces toward a back part of an antenna,

wherein the first surface includes a recessed region surrounded by a peripheral region provided with heat-dissipation fins,

wherein the first enclosure includes the first interface and a second interface for communication with the second device

wherein the second device comprises a second enclosure separate from the first enclosure, the second enclosure is configured to accommodate an RF (Radio Frequency) circuit configured to perform RF signal processing, the second device is configured to be protected according to a second degree of protection from water and dust ingress,

wherein the mounting bracket is configured to support the first device to be arranged adjacently to the second device with a space between the first enclosure and the second enclosure within the recessed region, and

wherein the second device is supported by the mounting bracket within the recessed region so as to be disposed between the first enclosure and the back part of the antenna.

10 . The method according to claim 9 , wherein the mounting bracket comprises a plate, a first stay member rising from one end of the plate, and a second stay member rising from another end of the plate.

11 . The method according to claim 9 , wherein the mounting bracket supports the first device in a manner such that a surface of the first device faces toward a surface of the second device.

12 . The method according to claim 9 , wherein the mounting bracket supports the first device in a manner such that the first device is arranged next to the second device.

13 . The method according to claim 9 , wherein the mounting bracket supports the first device and the second device so that the second device is positioned between the first device and the mounting bracket.

14 . The method according to claim 9 , wherein at least one of the first device and the second device is directly coupled to the mounting bracket.

15 . The method according to claim 9 , wherein the first enclosure is configured to protect the first device according to the first degree of protection from water and dust ingress, and wherein the second enclosure is configured to protect the second device according to the second degree of protection from water and dust ingress.
