Abstract

A modular monopole for wireless communications includes: an antenna module having a floor, a ceiling and a side wall that form an antenna compartment, wherein at least one antenna resides within the antenna compartment; a radio module having a floor, a ceiling and a side wall that form a radio compartment, wherein at least one remote radio unit (RRU) resides within the radio compartment; and a base. The base, the radio module, and the antenna module are arranged in vertically stacked relationship, with the base below the radio module and the antenna module above the radio module.

Claims

1. A modular monopole for wireless communications, comprising:

an antenna module having a floor, a ceiling and a side wall that form an antenna compartment, wherein at least one antenna resides within the antenna compartment;

a radio module having a floor, a ceiling and a side wall that form a radio compartment, wherein at least one remote radio unit (RRU) resides within the radio compartment; and

a base;

wherein the base, the radio module, and the antenna module are arranged in vertically stacked relationship, with the base below the radio module and the antenna module above the radio module.

2. The modular monopole defined in claim 1, further comprising a distribution module having a distribution compartment, wherein at least one cable distribution unit resides within the distribution compartment, the cable distribution unit configured to receive power conductors and optical fibers from a trunk cable, and wherein the distribution module is in vertically stacked relationship with the base, the radio module and the antenna module.

3. The modular monopole defined in claim 1, wherein the antenna module includes a first hollow post that extends between the antenna module floor and the antenna module ceiling, and wherein the radio module includes a second hollow post that extends between the radio module floor and the radio module ceiling.

4. The monopole assembly defined in claim 1, further comprising a cooling module in the base.

5. The monopole assembly defined in claim 4, wherein the radio module includes a frame having a floor, a ceiling, and a hollow post connecting the floor and the ceiling, the hollow post including an opening, the opening in fluid communication with the cooling module.

6. The modular monopole defined in claim 1, wherein the radio module includes:

an intake section in the side wall;

an exit section in the side wall, the exit section being above the intake section; and

at least one baffle positioned within the radio compartment that directs air that enters the radio module through the intake section to exit the radio module through the exit section.

7. The modular monopole defined in claim 6, wherein the exit section is located on a side of the side wall opposite the intake section.

8. The modular monopole defined in claim 7, wherein the at least one RRU is first and second RRUs, the second RRU being positioned above the first RRU, the radio module further including:

a second intake section in the side wall of the radio module;

a second exit section in the side wall of the radio module, the second exit section being above the second intake section; and

at least one second baffle positioned within the radio compartment that directs air that enters the second radio module through the second intake section to exit the second radio module through the second exit section.

9. A modular monopole for wireless communications, comprising:

an antenna;

a power and equipment module having a floor, a ceiling and a side wall that form a cavity, wherein at least one remote radio unit (RRU) resides within the cavity;

wherein the power and equipment module serves as the base of the monopole, with the antenna module are arranged in vertically stacked relationship above the power and equipment module.

10. The modular monopole defined in claim 9, wherein the power and equipment module includes a plurality of access doors.

11. The modular monopole defined in claim 9, wherein the power and equipment module includes one or more of:

a power meter, a main disconnect, an AC/DC rectifier, an AC load center, a diplexer, and a cooling system.

12. The modular monopole defined in claim 10, further comprising a cooling unit mounted to one of the doors.

13. A module for a monopole, comprising:

a housing having a window and a door covering the window, the door including a perforated panel, the perforated panel including a frame and a detachable perforated section;

wherein the perforated panel is mounted to the door without fasteners exposed to an external surface of the housing.

14. The module defined in claim 13, wherein a bracket is mounted on the door, and a vent retainer is fastened to the bracket and includes a bearing edge that bears against an inner surface of the frame.

15. The module defined in claim 14, wherein the bearing edge is arcuate and conforms to the inner surface of the frame.

16. The module defined in claim 14, wherein the vent retainer is fastened to the bracket via a clip nut that sandwiches the bracket and a bolt inserted into the clip nut.

17. A modular monopole for wireless communications, comprising:

an antenna;

a pole having a side wall that defines an inner lumen, wherein at least one wireless communications device resides within the lumen and wherein the pole includes at least one door; and

at least one stiffening element affixed to the inside surface of the side wall of the power and equipment module, wherein at least one stiffening element is affixed proximate to at least one door.

18. The monopole defined in claim 17, wherein the at least one stiffening element is oriented in a vertical direction.

19. The monopole defined in claim 17, wherein the at least one stiffening element comprises a substantially rectangular base with a plurality of flanges extending outwardly from lateral edges of the base in a direction substantially perpendicular to the surface of the base.

20. The monopole defined in claim 17, wherein the at least one stiffening element is welded to the inside surface of the cavity of the power and equipment module.
