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

1. A wireless communication apparatus comprising:

a first unit configured to be replaceable and comprising a first outdoor enclosure, the first outdoor enclosure being configured to accommodate a first electronic circuit module including a FEC (Forward Error Correction) encoder and a controller for performing digital signal processing, and to protect the first electronic circuit module from ingress of at least one of water and dust when installed outdoors;

a second unit comprising a second outdoor enclosure, the second outdoor enclosure being configured to accommodate a second electronic circuit module including a signal circuit for performing RF (Radio Frequency) signal processing and to protect the second electronic circuit module from ingress of at least one of water and dust when installed outdoors; and

a first mounting base configured to support the first unit to be arranged adjacently to the second unit, wherein

the first outdoor enclosure is configured to be connected to an external apparatus via a first communication cable and to the second outdoor enclosure via a second communication cable.

2. The wireless communication apparatus of claim 1, further comprising a second mounting base configured to fix the second unit to a structure.

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

4. The wireless communication apparatus of claim 1, wherein the first outdoor enclosure comprises a handle.

5. The wireless communication apparatus of claim 1, the first outdoor enclosure further comprises heat-dissipation fins.

6. The wireless communication apparatus of claim 1, wherein the first mounting base is configured to support the first unit in a manner such that a surface of the first outdoor enclosure faces toward a surface of the second outdoor enclosure.

7. The wireless communication apparatus of claim 1, wherein the first mounting base is configured to support the first unit in a manner such that the first outdoor enclosure is arranged next to the second outdoor enclosure.

8. A method comprising:

disposing a first unit adjacent to a second unit via a first mounting base, the first unit configured to be replaceable and comprising a first outdoor enclosure,

the first outdoor enclosure being configured to accommodate a first electronic circuit module including a FEC (Forward Error Correction) encoder and a controller for performing digital signal processing, the first outdoor enclosure being configured to protect the first electronic circuit module from ingress of at least one of water and dust when installed outdoors,

the second unit comprising a second outdoor enclosure, the second outdoor enclosure being configured to accommodate a second electronic circuit module including a signal circuit for performing RF (Radio Frequency) signal processing and to protect the second electronic circuit module from ingress of at least one of water and dust when installed outdoors;

connecting the first outdoor enclosure to an external apparatus via a first communication cable; and

connecting the first outdoor enclosure to the second outdoor enclosure via a second communication cable.

9. The method of claim 8, further comprising fixing the second unit on a structure via a second mounting base.

10. The method of claim 8, wherein the disposing comprising disposing the first unit in a manner such that a surface of the first outdoor enclosure faces toward a surface of the second outdoor enclosure.

11. The method of claim 8, wherein the disposing comprising disposing the first unit in a manner such that the first outdoor enclosure is arranged next to the second outdoor enclosure.
