Abstract

A wireless communication system is provided. The system includes a common module, is shaped as a sector of a cylinder and has a power supply. A sector radio module is coupled to the power supply and includes an access radio and an access antenna. The access antenna is configured to serve a sector of not more than 180°, and is also shaped as a sector of a cylinder.

First claim

What is claimed is:

1. A wireless communications system comprising:
a common module including a power supply that converts utility power to a voltage and current suitable to power access radio operation, wherein the common module is shaped as a sector of a cylinder and configured to be mounted on an exterior of an antenna mounting pole with the common module spaced apart from a base of the antenna mounting pole; and
a sector radio module coupled to and powered by the power supply of the common module, the sector radio module comprising a housing and including an access radio and an access antenna in the housing, wherein the access antenna is configured to serve a sector of not more than 180°, wherein the housing of the sector radio module is shaped as a sector of a cylinder and configured to be mounted adjacent the common module on the exterior of the antenna mounting pole, and wherein the sector radio module comprises a radome comprising a dielectric portion tuned to a frequency band of the access antenna.

2. The wireless communications system of claim 1 wherein the common module comprises a plurality of common modules and the sector radio module comprises a plurality of sector radio modules, wherein a combination of the plurality of sector radio modules provides 360 degree access radio coverage.

3. The wireless communications system of claim 2 wherein the plurality of sector radio modules comprises three sector radio modules, each sector radio module being shaped as a 120° sector of a cylinder.

4. The wireless communications system of claim 3 wherein the access antenna is configured to have a half power beam width of approximately 65°.

5. The wireless communications system of claim 1 wherein the sector radio module comprises a plurality of sector radio modules coupled to the common module.

6. The wireless communications system of claim 5 wherein the plurality of sector radio modules comprise a first sector radio module associated with a first wireless network operator and a second sector radio module associated with a second wireless network operator and mounted adjacent the first sector radio module on the antenna mounting pole.

7. The wireless communications system of claim 1 wherein the sector radio module comprises a radome comprising a lightweight molded plastic cover having perforations allowing intake of cooling air such that the cooling air is directed onto heat sinks of the access radio.

8. A wireless communications system comprising:
a common module including a power supply that converts utility power to a voltage and current suitable to power access radio operation, wherein the common module is shaped as a sector of a cylinder and configured to be mounted on an exterior of an antenna mounting pole with the common module spaced apart from a base of the antenna mounting pole; and
a sector radio module coupled to and powered by the power supply of the common module, the sector radio module comprising a housing and including an access radio and an access antenna in the housing, wherein the access antenna is configured to serve a sector of not more than 180°, wherein the housing of the sector radio module is shaped as a sector of a cylinder and configured to be mounted adjacent the common module on the exterior of the
antenna mounting pole, and wherein the sector radio module comprises a radome comprising a handle for lifting and/or installation.

9. The wireless communications system of claim 1 wherein the common module comprises a concave recess at a rear portion thereof that is sized and configured to receive the antenna mounting pole.

10. The wireless communications system of claim 1 wherein the sector radio module comprises a concave recess at a rear portion thereof that is sized and configured to receive the antenna mounting pole.

11. The wireless communications system of claim 1 comprising three common modules, three sector radio modules associated with a first network operator, and three sector radio modules associated with a second network operator, wherein the common modules supply power to the sector radio modules of both network operators.

12. The wireless communications system of claim 1 wherein the common module is configured to be selectively mounted on the exterior of the antenna mounting pole at a plurality of different heights.

13. The wireless communications system of claim 1 wherein the common module is configured to be mounted directly beneath the sector radio module on the exterior of the antenna mounting pole.

14. The wireless communication system of claim 1 , wherein the common module comprises a housing, wherein the power supply is within the housing.

15. The wireless communication system of claim 14 , wherein the common module being shaped as a sector of a cylinder comprises the housing being shaped as the sector of the cylinder.

16. A wireless communications system comprising:
an antenna mounting pole;
a common module including a power supply that converts utility power to a voltage and current suitable to power access radio operation; and
a sector radio module coupled to and powered by the power supply of the common module, the sector radio module including a housing, an access radio, and an access antenna, the access radio and the access antenna arranged within the housing, the access antenna being configured to serve a sector of not more than 180°;
wherein: the housing of the sector radio module is shaped as a sector of a cylinder and is mounted on an exterior of the antenna mounting pole;
the common module is shaped as a sector of a cylinder and is mounted directly beneath the sector radio module on the exterior of the antenna mounting pole; and
the sector radio module comprises a radome comprising a dielectric portion tuned to a frequency band of the access antenna.

17. The wireless communication system of claim 16 , wherein the common module comprises a housing, wherein the power supply is within the housing, and wherein the housing of the common module is spaced apart from a base of the antenna mounting pole.
