Abstract

In one embodiment, an antenna assembly in a cellular network has a radome that houses a plurality of antenna arrays and an electronics module. The electronics module has a weatherproof housing that encloses electronics for processing signals received by and transmitted from a first of the antenna arrays. The electronics module is physically removeably connected to an outer surface of the radome and electrically removeably connected to the first antenna array, such that the electronics module can be removed without (i) disrupting service to other antenna arrays and (ii) removing the antenna assembly from the cell tower on which the antenna assembly is installed.

First claim

What is claimed is:

1. An apparatus comprising a radome and (2) an active electronics module, wherein:
the radome is configured to support mounting of at least one antenna array behind the radome;
the active electronics module is configured to process at least one of (i) downlink signals transmitted by the at least one antenna array and (ii) uplink signals received at the at least one antenna array, wherein the apparatus further comprises an electronics-module mounting structure including a first reusable fastener, the electronics-module mounting structure configured to support removable attachment of the active electronics module behind the radome, such that
if the radome is mounted to a cell tower with the active electronics module removably attached behind the radome, then the active electronics module can be removed from behind the radome without removing the radome from the cell tower.

2. The apparatus of claim 1 , wherein, after the active electronics module has been removed from behind the radome, another active electronics module can be removably attached behind the radome without removing the radome from the cell tower.

3. The apparatus of claim 1 , wherein:
the electronics-module mounting structure further comprises a second reusable fastener complementary to the first reusable fastener;
the radome comprises one of the first and second reusable fasteners; and
the active electronics module comprises the other of the first and second reusable fasteners.

4. The apparatus of claim 1 , wherein:
the active electronics module is slidably attached behind the radome.

5. The apparatus of claim 3 , wherein:
the first reusable fastener is an elongated protrusion and the second reusable fastener is a complementary channel; and
the channel is configured to receive the elongated protrusion.

6. The apparatus of claim 1 , wherein:
the apparatus comprises the at least one antenna array mounted behind the radome; and
the active electronics module is removable from behind the radome without exposing the at least one antenna array to an environment outside of the radome.

7. The apparatus of claim 6 , wherein the active electronics module comprises:
circuitry configured to process at least one of (i) the downlink signals and (ii) the uplink signals; and
a housing, separate from the radome, configured to house the circuitry.

8. The apparatus of claim 7 , wherein:
the housing is weatherproof; and
the active electronics module is configured to be removable from behind the radome without exposing the circuitry to an environment outside of the housing.

9. The apparatus of claim 1 , wherein:
the apparatus comprises
at least first and second antenna arrays mounted behind the radome;
the active electronics module is configured to process at least one of (i) downlink signals transmitted by the first antenna array and (ii) uplink signals received at the first antenna array; and
the active electronics module is configured to be removable from the apparatus without disturbing service to the second antenna array.

10. The apparatus of claim 9 ,
wherein:
the apparatus further comprises at least one other active electronics module;
the at least one other active electronics module is configured to process at least one of (i) downlink signals transmitted by the second antenna array and (ii) uplink signals received at the second antenna array;
the at least one other active electronics module is attached behind the radome; and
the active electronics module is configured to be removable from the apparatus without disturbing service provided by the at least one other active electronics module to the second antenna array.

11. The apparatus of claim 9 , wherein:
the second antenna array is served by at least one base-station electronics module configured to process at least one of (i) downlink signals transmitted by the second antenna array and (ii) uplink signals received at the second antenna array;
the at least one base-station electronics module is installed at a base of the cell tower; and
the active electronics module is configured to be removable from behind the radome without disturbing service provided by the at least one base-station electronics module to the second antenna array.

12. The apparatus of claim 1 , wherein:
the apparatus comprises
the at least one antenna array mounted behind the radome;
the apparatus is installed on the cell tower; and
the at least one antenna array is served by a base-station electronics module installed at a base of the cell tower.

13. The apparatus of claim 1 , wherein the apparatus comprises cell-tower mounting structure,comprising:
a pole; and
at least one bracket configured to attach the radome to the pole.

14. The apparatus of claim 1 , wherein:
the apparatus comprises the first antenna array and a second antenna array;
the active electronics module is configured to process at least one of (i) downlink signals transmitted by the first antenna array and (ii) uplink signals received at the first antenna array; and
the active electronics module comprises:
circuitry configured to process at least one of (i) the downlink signals and (ii) the uplink signals; and
a housing, separate from the radome, configured to house the circuitry, wherein:
the housing of the active electronics module is removeably attached to the radome using the electronics module mounting structure; and
the active electronics module is configured to be removed from behind the radome without disturbing service to the second antenna array.

15. The apparatus of claim 1 , wherein:
the apparatus has a radome side on which the radome is mounted; and
the apparatus is configured to provide access to the active electronics module from a side other than the radome side such that the active electronics module can be removed without disturbing the radome side.

16. An apparatus comprising (1) a radome and (2) an active electronics module, wherein:
the radome is configured to support mounting of at least one antenna array behind the radome;
