Abstract

An antenna-RRU module for a cellular base station includes first, second and third antenna-RRU assemblies mounted on a pole. Each of the first, second and third antenna-RRU assemblies includes: a pole mounting bracket; a subassembly mounting bracket mounted on the pole mounting bracket; an antenna-RRU unit fixed relative to the subassembly mounting bracket; and a shroud mounted to at least partially cover the antenna-RRU unit. The pole mounting brackets of the first, second and third antenna-RRU assemblies are mounted on the pole at approximately 120 degree intervals.

First claim

That which is claimed is:

1. An antenna-RRU assembly, comprising:
an antenna-RRU unit;
a subassembly mounting bracket fixed relative to the antenna-RRU unit, the subassembly mounting bracket having a plurality of hooks; and
a pole mounting bracket having a plurality of vertically-oriented slots;
wherein the hooks of the subassembly mounting bracket are inserted into the slots of the pole mounting bracket to mount the subassembly mounting bracket to the pole mounting bracket.

2. The assembly defined in claim 1 , further comprising a shroud that partially encloses the antenna-RRU unit, the shroud including a window through which the antenna-RRU unit can transmit signals.

3. The assembly defined in claim 1 , further comprising a spool having a pole, and wherein the pole mounting bracket is mounted to the pole.

4. The assembly defined in claim 1 , wherein the pole mounting bracket comprises a concave portion and first and second wings, and wherein the slots are located in the first and second wings.

5. The assembly defined in claim 4 , wherein the pole mounting bracket includes a second plurality of slots in the concave portion.

6. The assembly defined in claim 1 , wherein the pole mounting bracket includes tabs at a lower end thereof, and wherein the subassembly mounting bracket is secured to the tabs.

7. The assembly defined in claim 1 , wherein the subassembly mounting bracket is attached directly to the antenna-RRU unit.

8. The assembly defined in claim 1 , wherein the antenna-RRU unit is fixed directly to an antenna-RRU mounting bracket, and wherein the antenna-RRU mounting bracket is fixed directly to the subassembly mounting bracket.

9. An antenna-RRU module for a cellular base station, comprising first, second and third antenna-RRU assemblies mounted on a pole, each of the first, second and third antenna-RRU assemblies comprising:
a pole mounting bracket;
a subassembly mounting bracket mounted on the pole mounting bracket;
an antenna-RRU unit fixed relative to the subassembly mounting bracket; and
a shroud mounted to at least partially cover the antenna-RRU unit, wherein the shroud is configured so that a window of a desired size for a specific antenna-RRU unit is formed into the front wall of the shroud;
wherein the pole mounting brackets of the first, second and third antenna-RRU assemblies are mounted on the pole at approximately 120 degree intervals.

10. The module defined in claim 9 , wherein the pole is part of a spool having a base and a ceiling.

11. The module defined in claim 10 , wherein each of the shrouds is mounted to the spool.

12. The module defined in claim 11 , wherein the spool further comprises a mounting band, and wherein each of the shrouds is mounted to the mounting band.

13. The module defined in claim 9 , wherein the pole mounting brackets are mounted to the pole with at least one radial clamp.

14. The module defined in claim 9 , further comprising fastening members extending between adjacent pole mounting brackets to mount the pole mounting brackets to the pole.

15. The module defined in claim 9 , wherein an end cap overlies the ceiling of the spool.

16. The module defined in claim 9 , in combination with an antenna module mounted above the antenna-RRU module.

17. The module defined in claim 9 , wherein each of the subassembly mounting brackets includes a plurality of hooks, and each of the pole mounting brackets includes a plurality of slots that receive the hooks.

18. The module defined in claim 9 , wherein, in each of the first, second and third antenna-RRU assemblies, the subassembly mounting bracket is attached directly to the antenna-RRU unit.

19. The module defined in claim 9 , wherein, in each of the first, second and third antenna-RRU assemblies, the antenna-RRU unit is fixed directly to an antenna-RRU mounting bracket, and wherein the antenna-RRU mounting bracket is fixed directly to the subassembly mounting bracket.

20. The module defined in claim 9 , wherein the antenna-RRU units are 5G units.
